2000-12-11 Gary Thomas <gthomas@redhat.com> * cdl/hal_arm_ebsa285.cdl: Enable CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_GUARANTEED - required to fully support RedBoot networking I/O and ^C. 2000-12-08 Jonathan Larmour <jlarmour@redhat.com> * cdl/hal_arm_ebsa285.cdl: Build redboot_cmds.c in the right place. 2000-12-04 Hugo Tyson <hmt@redhat.com> * include/hal_cache.h: Consistently ensure that ARM registers used in MCR ops to cache-control coprocessors, where the data doesn't matter, all actually have data zero ("SBZ") as in the Jaggar book. This may well not be necessary, but for the sake of making sure... 2000-12-01 Gary Thomas <gthomas@redhat.com> * src/redboot_cmds.c: Add prototype to remove warning. 2000-11-30 Gary Thomas <gthomas@redhat.com> * src/redboot_cmds.c (do_exec): Complete support for loading Linux, including use of an initial ramdisk image. 2000-12-01 Hugo Tyson <hmt@redhat.com> * include/hal_cache.h: Define addressable cache line operations HAL_DCACHE_STORE(), HAL_DCACHE_INVALIDATE(), HAL_DCACHE_FLUSH() now that I have understood how come the test (kcache2) was failing. See kernel ChangeLog for details. Also tidied up a couple of other minor details. 2000-11-28 Drew Moseley <dmoseley@redhat.com> * misc/redboot_RAM.cfg: Implement CYGSEM_REDBOOT_BSP_SYSCALLS. * misc/redboot_ROM.cfg: Ditto. * src/ebsa285_misc.c (ebsa285_program_new_stack): New function for switching to an application stack when running a program under a ROM monitor. * cdl/hal_arm_sa11x0_ebsa285.cdl: Define HAL_ARCH_PROGRAM_NEW_STACK. 2000-11-19 Gary Thomas <gthomas@redhat.com> * cdl/hal_arm_ebsa285.cdl: Define CYGBLD_HAL_PLATFORM_IO_H. * src/redboot_cmds.c: Fix 'exec' command to handle Linux kernel. Includes support to relocate image before startup. * cdl/hal_arm_ebsa285.cdl: Fix some minor comments. 2000-11-14 <gthomas@laptop_local> * include/hal_ebsa285.h (EBSA285_RAM_BANK0_BASE): Correct for SA110/285. 2000-11-13 <gthomas@laptop_local> * cdl/hal_arm_ebsa285.cdl: Fix out of date ROM/RAM description. 2000-10-18 Gary Thomas <gthomas@redhat.com> * src/redboot_cmds.c: New file: only built in redboot, for a platform specific command to exec code with no MMU intervention. This is used to execute standard Linux kernels with as little change/perturbation as possible. * include/hal_ebsa285.h (EBSA285_RAM_BANK0_BASE): New symbol for redboot_cmds.c * cdl/hal_arm_ebsa285.cdl: Add build redboot_cmds.c -> libextras. 2000-09-17 Gary Thomas <gthomas@redhat.com> * cdl/hal_arm_ebsa285.cdl: Add platform/cpu identification strings. 2000-09-06 Hugo Tyson <hmt@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl (CYGHWR_HAL_ARM_EBSA285_PCI_MEM_MAP_BASE CYGHWR_HAL_ARM_EBSA285_PCI_MEM_MAP_SIZE): Add strong constraints to the alignment and size of the PCI window by means of legal_values lists so that runtime can check that the MLTs opinion of the memory usage is valid. [This is related to CR 902624-CR, "MLT needs to be configuration aware"] * include/pkgconf/mlt_arm_ebsa285_ram.h: * include/pkgconf/mlt_arm_ebsa285_ram.ldi: * include/pkgconf/mlt_arm_ebsa285_ram.mlt: * include/pkgconf/mlt_arm_ebsa285_rom.h: * include/pkgconf/mlt_arm_ebsa285_rom.ldi: * include/pkgconf/mlt_arm_ebsa285_rom.mlt: Regenerate these from the MLT featuring a "pci_window" section in order to prevent the greedy heap code comsuming all of memory. The pci_window section is from 0xf00000 of size 0x100000 i.e. Megabyte number 15, at the top of (default) memory. Unfortunately my previous quick fix (2000-08-15) for this had not in fact worked, because of the "clever" code which looks for add-in memory and consumes *that* too, unconditionally... [This is related to CR 902624-CR, "MLT needs to be configuration aware"] 2000-08-18 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_platform_setup.h: Initialize the world if you are blowing away previous state rather than only in ROM start. This makes it possible to create a standalone RAM app that will work with either RedBoot in ROM or old-style GDB stubs, or any other loader you might find. Incidentally I now understand why Gary found it necessary to force PCI reset (2000-08-07) - with RedBoot in ROM, the RAM app was unconditionally reinitializing the PCI bus when it was already initialized, without resetting it. We cannot play the same game here as with hal_platform_setup.h - I tried - because otherwise the net cannot re-initialize itself; the scan for devices fails. 2000-08-16 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_platform_setup.h (CYGHWR_LED_MACRO): Use an address that works for a customer's own not-quite-exactly-like an EBSA board. It works fine on a real EBSA too of course. [CASE 104355] 2000-08-15 Hugo Tyson <hmt@cygnus.co.uk> * include/pkgconf/mlt_arm_ebsa285_ram.h (CYGMEM_REGION_ram_SIZE): * include/pkgconf/mlt_arm_ebsa285_rom.h (CYGMEM_REGION_ram_SIZE): Do not "helpfully" consume all of memory for the heap, including PCI space, unconditionally; leave the PCI window alone. 2000-08-07 Gary Thomas <gthomas@redhat.com> * include/plf_io.h (HAL_PCI_INIT): Force PCI reset, just for good measure. 2000-08-03 Gary Thomas <gthomas@redhat.com> * src/ebsa285_misc.c (hal_delay_us): New routine, used for hardware delays when no kernel timers are available. * include/hal_platform_setup.h (PLATFORM_SETUP1): Don't re-init hardware for RAM startup. Doing so keeps network debugging from working (PCI gets shutdown, etc). 2000-07-25 Jonathan Larmour <jlarmour@redhat.co.uk> * include/pkgconf/mlt_arm_ebsa285_ram.mlt: Add heap1 section for malloc * include/pkgconf/mlt_arm_ebsa285_ram.ldi: Regenerate * include/pkgconf/mlt_arm_ebsa285_ram.h: Regenerate * include/pkgconf/mlt_arm_ebsa285_rom.mlt: Add heap1 section for malloc * include/pkgconf/mlt_arm_ebsa285_rom.ldi: Regenerate * include/pkgconf/mlt_arm_ebsa285_rom.h: Regenerate * src/ebsa285_misc.c (hal_arm_mem_real_region_top): Remove warnings 2000-07-17 Jesper Skov <jskov@redhat.com> * src/hal_diag.c (cyg_hal_plf_serial_isr): Return value was not always correct. 2000-07-04 Jesper Skov <jskov@redhat.com> * src/plf_stub.c: [deleted] * src/hal_diag.c: * src/ebsa285_misc.c: * include/plf_stub.h: * include/hal_platform_ints.h: * include/hal_diag.h: * cdl/hal_arm_ebsa285.cdl: Changed to use virtual vector table. 2000-07-04 Jonathan Larmour <jlarmour@redhat.co.uk> * cdl/hal_arm_ebsa285.cdl: This platform implements CYGINT_HAL_ARM_MEM_REAL_REGION_TOP * src/ebsa285_misc.c (hal_arm_mem_real_region_top): Add to allow true memory sizes to be reported, for the benefit of dynamic memory systems 2000-06-19 Gary Thomas <gthomas@redhat.com> * include/hal_platform_setup.h: 'hal_dram_size' is now a properly defined variable (no more fixed 0x40 stuff). 2000-06-18 Gary Thomas <gthomas@redhat.com> * include/pkgconf/mlt_arm_ebsa285_ram.ldi: * include/pkgconf/mlt_arm_ebsa285_ram.mlt: * include/pkgconf/mlt_arm_ebsa285_rom.ldi: * include/pkgconf/mlt_arm_ebsa285_rom.mlt: Incorporate new fixed vectors (used on all ARM platforms). 2000-02-29 Jonathan Larmour <jlarmour@redhat.co.uk> * include/pkgconf/mlt_arm_ebsa285_ram.h: * include/pkgconf/mlt_arm_ebsa285_ram.ldi: * include/pkgconf/mlt_arm_ebsa285_ram.mlt: * include/pkgconf/mlt_arm_ebsa285_rom.h: * include/pkgconf/mlt_arm_ebsa285_rom.ldi: * include/pkgconf/mlt_arm_ebsa285_rom.mlt: Align all sections on word boundaries 2000-02-24 Hugo Tyson <hmt@cygnus.co.uk> * src/mem285.S (__mem285_init): Re-do the SDRAM initialization until a consistent answer is acquired twice in a row. We have been seeing test failures with the SDRAM initialization in the board with 32Mb - the SDRAM setup is screwey; hope this fixes it. 2000-02-21 Gary Thomas <gthomas@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Remove -mstructure-size-boundary=8 option - no longer needed to build working network code. 2000-02-18 Jonathan Larmour <jlarmour@redhat.co.uk> * cdl/hal_arm_ebsa285.cdl (CYGBLD_BUILD_GDB_STUBS): When building stubs, define every dependency required here rather than in the template 2000-02-10 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_cache.h (HAL_ICACHE_INVALIDATE_ALL): (HAL_DCACHE_INVALIDATE_ALL): Also invalidate TLBs in case the reason for the cache invalidate is a MM table rewrite. 2000-02-10 Jesper Skov <jskov@redhat.com> * include/plf_stub.h: HAL_STUB_PLATFORM_STUBS_INIT->HAL_STUB_PLATFORM_INIT * src/hal_diag.c: * misc/stubrom.perm: [removed] * misc/STUBS_config: [added] * include/pkgconf/hal_arm_ebsa285.h: Removed stubs as a legal startup type. 2000-02-09 Hugo Tyson <hmt@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl (CYGBLD_GLOBAL_CFLAGS): Permanently set the -mstructure-size-boundary=8 compilation option, as required by the initial version of the OpenBSD network stack port, currently software under development. 2000-02-07 Jesper Skov <jskov@redhat.com> * cdl/hal_arm_ebsa285.cdl: Use cpu option when linking. 2000-02-04 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_platform_setup.h (INIT_XBUS_ACCESS): (CYGHWR_LED_MACRO): Fix a typo - "and" alone doesn't set conditions, so branch depending on "PCI arbiter enabled" was taken randomly. 2000-02-03 Jesper Skov <jskov@redhat.com> * cdl/hal_arm_ebsa285.cdl: Implements stubs. 2000-01-31 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_ebsa285.h: Correct misleading comment. 2000-01-27 Jesper Skov <jskov@redhat.com> * cdl/hal_arm_ebsa285.cdl: Moved part of stubs build rule to common HAL. Changed description. 2000-01-26 Jesper Skov <jskov@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Removed below. Target does not have CygMon support. 2000-01-25 Jesper Skov <jskov@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Added cygmon console device config. Added make rule for binary conversion of cygmon image. 2000-01-24 Jesper Skov <jskov@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Add stubs build rule. 2000-01-24 John Dallaway <jld@cygnus.co.uk> * cdl/*.cdl: Remove obsolete option CYGTST_TESTING_IDENTIFIER. 2000-01-19 Hugo Tyson <hmt@cygnus.co.uk> * cdl/*.cdl: Add descriptions to a number of options &c which were lacking same, also tidied up other typos as noticed en passant. 2000-01-10 Hugo Tyson <hmt@cygnus.co.uk> * src/ebsa285_misc.c (hal_IRQ_handler): Conditionally remove debugging check for FIQ sources being active at customer's request; they are now using FIQ via VSR so the warning message is unwanted. 1999-11-25 Jonathan Larmour <jlarmour@cygnus.co.uk> * src/hal_diag.c: Conditionalize def of diag_buffer for only when it's explicitly wanted and someone hacks the code (hal_diag_write_char): Likewise 1999-11-25 Gary Thomas <gthomas@cygnus.co.uk> * include/pkgconf/mlt_arm_ebsa285_rom.h: * include/pkgconf/mlt_arm_ebsa285_ram.h: Update 'do not edit' strings. 1999-11-16 Hugo Tyson <hmt@cygnus.co.uk> * tests/sdram0.cxx: New file to test SDRAM initialization. It is somewhat EBSA specific in that it sanity checks the control reg setup as well as testing memory per se. * cdl/hal_arm_ebsa285.cdl: build the new test. * tests/PKGconf.mak: New file: build the new test. 1999-11-16 Hugo Tyson <hmt@cygnus.co.uk> * src/mem285.S: Rewrite, essentially: it was the only way to get a good enough handle on what this nasty, trick stuff does. I'm very happy with it now. It's also callable for RAM startup too, to happily count up the RAMs as initialized: no guessing ever again! * include/hal_platform_setup.h: Delete some code! Now that mem285 initialization is sorted out, it's cool to do exactly the same thing for ROM and RAM startup; the mem init code differs, mind, to just add up the memory sizes in RAM start. 1999-11-10 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_platform_setup.h (PLATFORM_FLUSH_DISABLE_CACHES): Also flush TLBs - this is vital when changing cachability &c during startup. Also do that same flush in ROM start, for when we build to run in flash block #1 following POST executing, when "stuff" might be in an odd state. 1999-11-09 Gary Thomas <gthomas@cygnus.co.uk> * include/pkgconf/mlt_arm_ebsa285_ram.h: * include/pkgconf/mlt_arm_ebsa285_rom.h: New files. * include/pkgconf/mlt_arm_ebsa285_ram.ldi: * include/pkgconf/mlt_arm_ebsa285_ram.mlt: * include/pkgconf/mlt_arm_ebsa285_rom.ldi: * include/pkgconf/mlt_arm_ebsa285_rom.mlt: Update with correct memory layout. * src/hal_diag.c: Honor GDB_DISABLE option. 1999-11-09 Jesper Skov <jskov@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: * include/pkgconf/hal_arm_ebsa285.h: * src/ebsa285_misc.c: Remap PCI accessible memory as non-cachable. Changed default PCI mapped memory to the top 1MB of a 16MB system. 1999-11-01 Jesper Skov <jskov@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Remove define_proc comments. 1999-10-29 Jesper Skov <jskov@cygnus.co.uk> * include/pkgconf/mlt_arm_ebsa285_ram.ldi: * include/pkgconf/mlt_arm_ebsa285_rom.ldi: * include/pkgconf/mlt_arm_ebsa285_ram.mlt: * include/pkgconf/mlt_arm_ebsa285_rom.mlt: Increased memory size to 16MB. 1999-10-27 Jesper Skov <jskov@cygnus.co.uk> * src/hal_diag.c: Fixed conditional include. 1999-10-26 Hugo Tyson <hmt@cygnus.co.uk> * src/hal_diag.c (hal_diag_write_char): Use new macro CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION and its mate to control stepping through gdb $O packet output. 1999-10-26 Jesper Skov <jskov@cygnus.co.uk> * include/hal_platform_setup.h (CYGHWR_LED_MACRO): Define. 1999-10-26 John Dallaway <jld@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Rename CYGBLD_GLOBAL_PREFIX to CYGBLD_GLOBAL_COMMAND_PREFIX 1999-10-20 John Dallaway <jld@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Define build-related and memory layout-related CDL options. 1999-10-11 Jesper Skov <jskov@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: * include/plf_io.h: * include/pkgconf/hal_arm_ebsa285.h: Added configurability of EBSA memory accessible from PCI space. * src/ebsa285_misc.c (hal_bsp_mmu_init): Folded XBus into 21285 regs. * include/hal_platform_setup.h (PLATFORM_SETUP1): Disable cache first. 1999-10-06 John Dallaway <jld@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Define CYGTST_TESTING_IDENTIFIER. 1999-10-05 Hugo Tyson <hmt@cygnus.co.uk> * support/linux/safl_util/sa_flash.c: Add a lot of extra diagnostics and some new options; did this in the course of finding out whether a board really was dead or not, so may as well commit it. 1999-09-24 Jesper Skov <jskov@cygnus.co.uk> * include/plf_io.h (HAL_PCI_INIT): Fix rookie code bug. * include/hal_ebsa285.h (SA110_XBUS_XCS2): Fix typo. 1999-09-01 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_ebsa285.h (ARM_MMU_SECTION): Move these macros and memory-layout structure definitions here from ebsa285_misc.c so that others can use them. * src/ebsa285_misc.c (hal_IRQ_handler): Scan FIQ sources also and print a warning if any are active. (hal_hardware_init): Clear the FIQ enable mask at startup too; this was assumed to be cleared at reset, but just in case... (ARM_MMU_SECTION): Move these macros and memory-layout structure definitions from here to include/hal_ebsa285.h so that others can use them. * src/hal_diag.c (hal_diag_write_char): Do not unconditionally poke the XBUS LED location - XBUS may not be available if internal 21285 arbiter is in use. (hal_diag_write_char): Fix warnings for proto of cyg_hal_gdb_interrupt(). 1999-09-01 Jesper Skov <jskov@cygnus.co.uk> * include/plf_io.h (HAL_PCI_CONFIG_ADDRESS): Use alternate config space 0 addressing so all 32 devices can be scanned. 1999-08-27 Jesper Skov <jskov@cygnus.co.uk> * include/hal_ebsa285.h: Added some timer bits. 1999-08-24 Jesper Skov <jskov@cygnus.co.uk> * include/hal_ebsa285.h (SA110_XBUS_CYCLE_ARBITER_ENABLED): Added. * include/hal_platform_setup.h (INIT_XBUS_ACCESS): Check jumper settings and behave accordingly. * include/plf_io.h (HAL_PCI_TRANSLATE_INTERRUPT): Fixed interrupt vector table to match observed behavior. 1999-08-19 Jesper Skov <jskov@cygnus.co.uk> PR 20326 * include/hal_cache.h: Set MMU/align flag as well. 1999-08-19 Jesper Skov <jskov@cygnus.co.uk> * include/hal_platform_setup.h (BASIC_PCI_SETUP): [+untabified] * include/plf_io.h (HAL_PCI_INIT): Changed PCI enable comment to match actual behavior. 1999-08-17 Jesper Skov <jskov@cygnus.co.uk> * include/plf_io.h: Rename HAL_PCI_CONFIG_INTERRUPT to HAL_PCI_TRANSLATE_INTERRUPT. Read _PIN instead of _LINE. 1999-08-16 Jesper Skov <jskov@cygnus.co.uk> * include/plf_io.h (HAL_PCI_CONFIG_INTERRUPT): Added. 1999-08-13 Jesper Skov <jskov@cygnus.co.uk> * include/plf_io.h: Renamed macros and added resource information. Renaming again. 1999-08-12 John Dallaway <jld@cygnus.co.uk> * cdl/hal_arm_ebsa285.cdl: Define CYG_HAL_STARTUP and CYGHWR_MEMORY_LAYOUT. 1999-08-12 Jesper Skov <jskov@cygnus.co.uk> * include/plf_io.h: Added PCI macros. 1999-08-12 Jesper Skov <jskov@cygnus.co.uk> * cdl: Added CDL for ebsa. 1999-08-12 Jesper Skov <jskov@cygnus.co.uk> * include/hal_platform_setup.h: * include/hal_ebsa285.h: Renamed some PCI registers and moved out generic PCI stuff. 1999-08-10 Jesper Skov <jskov@cygnus.co.uk> * include/hal_ebsa285.h: Added more definitions. * include/plf_stub.h (HAL_STUB_PLATFORM_RESET): Defined. 1999-08-04 Jesper Skov <jskov@cygnus.co.uk> * src/ebsa285_misc.c (ARM_ACCESS_TYPE_x): each domain has two bits. 1999-07-26 John Dallaway <jld@cygnus.co.uk> * include/pkgconf/mlt_arm_ebsa285_rom.mlt: * include/pkgconf/mlt_arm_ebsa285_ram.mlt: Fix memory section alignments to match those of the pre-built linker script fragments. 1999-07-26 Hugo Tyson <hmt@cygnus.co.uk> * include/pkgconf/mlt_arm_ebsa285_rom.mlt: * include/pkgconf/mlt_arm_ebsa285_ram.mlt: Make these match the .ldi files that do the linking proper, so that the process is reversible and the .ldi files recreatable. 1999-07-26 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_platform_ints.h (CYGDBG_HAL_CTRLC_ISR): Define this if needed so that the arch HAL can conditionally call our poll routine. Problem is that CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT *is* defined for platforms that do not support it. 1999-07-23 Hugo Tyson <hmt@cygnus.co.uk> * src/hal_diag.c (hal_ctrlc_isr): Define this function, which is called from the default ISR, if CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT is defined. It looks for a ^C in the serial input and bangs out with a breakpoint if one arrives. Note that you cannot do much at all after this bp, except examine the stack and see where the program had got to. (hal_diag_write_char): Do not eat response characters from GDB: leave them for the ISR mentioned above to test for ^C. * src/ebsa285_misc.c (hal_hardware_init): Unmask the interrupt for serial reception, so that we can scan for incoming ^C, if the option CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT is defined. 1999-07-23 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_platform_ints.h (CYG_GDB_DEV_INT, CYG_DIAG_DEV_INT): define these so that interrupting using ^C and so on will work. 1999-07-22 Hugo Tyson <hmt@masala.cygnus.co.uk> * support/README: New file. * support/linux/README: New file. * support/linux/safl_util/README: New file. * support/linux/safl_util/Makefile: New file. * support/linux/safl_util/sa_flash.c: New file. * support/linux/safl_util/safl.c: New file. Keep the devo safl_utils for programming ebsa-285 FLASH in the eCos tree too, so that it gets into our releases. 1999-07-21 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_platform_setup.h (PLATFORM_SETUP1): Get ROM startup to work OK; tidy up RAM start in consequence. Do not set CYGHWR_HAL_ARM_HAS_MMU so that we jump straight into high ROM. Remove consequently unused macros. * src/ebsa285_misc.c: Pass DRAM size as detected at startup around correctly; worry less about alignment of MMU page table thingy. * src/hal_diag.c: Make ROM startup systems output in clear. * src/mem285.S: Get rid of all that IMM() nonsense. * misc/stubrom.perm: NEW FILE: Add instructions for making a STUBROM. * include/pkgconf/mlt_arm_ebsa285_rom.ldi: Get the numbers right for ROM startup. 1999-07-19 Hugo Tyson <hmt@masala.cygnus.co.uk> * src/mem285.S: New file: offers routine __mem285_init, for DRAM sizing before the MMU is set up. Code borrowed from CygMon/BSP of course. * src/ebsa285_misc.c: Add the meat of the 'C' initialization here; MMU initialization is the main addition. Code borrowed from CygMon/BSP. * src/PKGconf.mak (COMPILE): Add mem285.S, which contains tricky DRAM sizing and init code - which of course can only be run from ROM, since it is damaging to the contents of DRAM. * include/hal_platform_setup.h (PLATFORM_SETUP1): Add required startup code in various macros to make constructing one phrase for ROM vs RAM startup easier, and for debug. Code borrowed from CygMon/BSP. * src/hal_diag.c (hal_diag_init): Initialize the hardware, by setting the baud rate. * include/hal_ebsa285.h (ARM_FIRST_LEVEL_PAGE_TABLE_SIZE): Add this and a few other symbols for the DRAM sizing and MMU init code. 1999-07-16 Hugo Tyson <hmt@cygnus.co.uk> * include/pkgconf/hal_arm_ebsa285.h: Typo in tidy up of config info. Doh! 1999-07-16 Hugo Tyson <hmt@cygnus.co.uk> * include/pkgconf/hal_arm_ebsa285.h: Tidy up config info. 1999-07-15 Hugo Tyson <hmt@cygnus.co.uk> * src/ebsa285_misc.c (hal_hardware_init): Enable the caches in here; they are now disabled during startup. * include/hal_platform_setup.h (PLATFORM_SETUP1): Added code to disable caches [if RAM start] and switch to the ROM address [regardless, since it's the RAM addr if RAM start so harmless] * include/pkgconf/mlt_arm_ebsa285_rom.ldi: Set up some of the values here while they are in my head; see above. 1999-07-15 Hugo Tyson <hmt@cygnus.co.uk> * include/hal_cache.h: Tidy up cache macros and make semantics better match what the GDB stubs require. 1999-07-15 Hugo Tyson <hmt@cygnus.co.uk> * include/sa-110.h: removed, it was added in error. Its contents live in include/hal_ebsa285.h 1999-07-14 Hugo Tyson <hmt@cygnus.co.uk> New component: StrongARM EBSA-285 development board support.
