2003-07-29  Gary Thomas  <gary@mlbassoc.com> on behalf of
2003-07-29  Yoshinori Sato <ysato@users.sourceforge.jp>	

	* src/sh.ld: Handle all bss* sections (newer compilers).

2003-07-18  Nick Garnett  <nickg@balti.calivar.com>

	* cdl/hal_sh.cdl:
        Changed values for CYGNUM_HAL_RTC_NUMERATOR,
        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
        "default_value" from "calculated". This makes it easier
        to change these values globally.
        
2003-04-17  Jonathan Larmour  <jifl@eCosCentric.com>

	* include/hal_var_bank.h (HAL_THREAD_INIT_CONTEXT): Align stack
	pointer before using it.
	* include/hal_var_sp.h (HAL_THREAD_INIT_CONTEXT): Ditto.

2003-04-10  Nick Garnett  <nickg@balti.calivar.com>

	* src/sh.ld:
	Added entry for .stack section in data section.

2003-03-11  Mark Salter  <msalter@redhat.com>

	* src/redboot_linux_exec.c (do_exec): Call eth_drv_stop as necessary.

2003-01-31  Mark Salter  <msalter@redhat.com>

	* src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
	handle exit.

2002-08-02  Andrew Lunn <Andrew.Lunn@ascom.ch>

	* cdl/hal_sh.cdl: The Redboot exec command can now be 
	  disabled by CDL
	
2002-04-30  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_sp.inc: Allow variant to provide custom
	interrupt vector layout. This means the size of
	hal_interrupt_handlers/objects/data can be reduced if the vector
	layout is sparse. Something similar could be done for
	_HW_EXEC_ENTRY_TABLE, saving exception_vector_int entries in the
	$vectors_code block. However, this code usually resides in flash
	so there's not much point given todays flash block sizes.

	* cdl/hal_sh.cdl: Added CYGHWR_HAL_SH_FPU and
	CYGHWR_HAL_SH_NO_FPU, allowing an arch level control of FPU
	related tests.
	Skipping test handled in a different way now, so the implements
	statement has been deleted again.

2002-04-29  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_bank.inc: Define hal_exception_entry_extras and
	hal_interrupt_entry_extras.
	* include/hal_var_sp.inc: Define hal_exception_entry_extras and
	hal_interrupt_entry_extras. Disable interrupts on exception
	entry.
	* src/vectors.S: Call hal_exception_entry_extras and
	hal_interrupt_entry_extras.

2002-04-29  Jonathan Larmour  <jlarmour@redhat.com>

	* src/vectors.S:
	Don't use .file as it can confuse debugging since the .file
	doesn't contain the path and therefore the debugger will never
	know where it lives! This conflicts with using -Wa,--gstabs.

2002-04-15  Jonathan Larmour  <jlarmour@redhat.com>

	* src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
	__do_syscall.

2002-04-22  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_sp.inc: 7044 needs different vector layout than
	76xx since its vectors are hardwired.

2002-04-18  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_sp.inc: Do no translation of entry address if
	cache module defines CYGARC_SH_MOD_CAC_NO_WINDOWS.

	* include/hal_intr_vecs.h: Move all vectors after IRQ7 to variant
	header. Define _IRQ and _LVL for all of the first 7
	interrupts. Define CYGNUM_HAL_INTERRUPT_LVL_MAX

2002-03-06  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_sp.inc: Fix asm comments.

	_CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Same.

2002-02-26  Jesper Skov  <jskov@redhat.com>

	* include/hal_intr_vecs.h: Use DATA_ACCESS vector names instead of
	ADDRESS_ERROR names.

2002-02-15  Jesper Skov  <jskov@redhat.com>

	* src/sh_stub.c (__single_step): Use normal breakpoint instruction
	(trapa #32) for single-stepping.
        On the SH2 the use of trapa#255 causes a different (and unhandled)
	exception, in the range reserved for application
	exceptions/interrupts.

2002-02-14  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_bank.h: Switch mach/macl entries.
	* include/hal_var_sp.h: Same.

	32-64.
	(hal_cpu_save_regs): Remember to adjust SP for R0 save location.
	(hal_cpu_restore_regs_return): Rewritten to fix errors and allow
	SP to be changed from GDB.

2002-02-13  Jesper Skov  <jskov@redhat.com>

	* src/context.S (hal_thread_load_context): Load up stack pointer
	before enabling interrupts.
	
	* include/hal_var_sp.inc: Fetch the VSR pointer and jump to it
	instead of into the VSR table.
	(hal_cpu_restore_regs_return): adjust sp to point to exception
	state before returning.

2002-02-08  Jesper Skov  <jskov@redhat.com>

	* src/vectors.S: tweak ROMRAM relocation code.

2002-02-07  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_sp.inc: Moved _reset code to below vectors.

2002-01-17  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_bank.inc: Include SH3 register references. Make
	better use of some delay slots.

	* src/vectors.S: Don't save exception/interrupt state on stack
	with debug markers. Load up event value in R4 before calling
	hal_intc_decode so it can be a nop if desired. Removed some SH3
	register references.

	* include/hal_var_sp.inc: Include SH2 offsets, export
	_HW_EXC_ENTRY_TABLE, fix some typos.

	* include/hal_intr_vecs.h: IRL vectors renamed. Added IRQ
	vectors.

2002-01-16  Jesper Skov  <jskov@redhat.com>

	* include/hal_var_bank.h: Fix typo.

	* src/sh_stub.c (__computeSignal): Only handle defined vectors.

	other vectors. Provide MEM_FAULT vector range.
	* include/hal_var_sp.inc: Changes for NMI-as-interrupt-0.
	* include/hal_var_sp.h: Renamed vector to event to share code.

	* include/hal_intr_excevt.h: Added MEM_FAULT vector ranges and
	CYGHWR_SH_RTC_TIMER_IS_TMU.
	* src/hal_misc.c (hal_delay_us): Only build if
	CYGHWR_SH_RTC_TIMER_IS_TMU. Use MEM_FAULT vector range.

	* include/hal_intr.h: Deleted clock controls.

	* cdl/hal_sh.cdl: Use CYGNUM_HAL_RTC_PRESCALE instread of
	module-specific prescale variable.

	* include/hal_intr_excevt.h (_CYGNUM_HAL_VECTOR_FIRST_MEM_FAULT,
	_CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Define.
	* include/hal_intr_vecs.h: Same. 
	* src/hal_misc.c (cyg_hal_exception_handler): Use new _MEM_FAULT
	vector range.


	* include/hal_intr_vecs.h: Removed RTC code.

	* include/hal_arch.h: Changed breakpoint instruction to match that
	used in GDB 5.1.
	It also makes better sense on the SH2.

	* include/hal_intr_excevt.h: Interrupt/exception vectors and clock
	handling code moved here...
	* include/hal_intr.h: From here.
	* include/hal_intr_vecs.h: Interrupt/exception vector layout +
	clock handling for SH1/SH2 variants.

	* include/hal_var_sp.inc: Added some comments, fixed number of
	pre-VSR vectors, renamed HW_VSR_TABLE to HW_EXC_ENTRY_TABLE to
	avoid confusion (it has nothing to do with eCos VSRs). Finally,
	made the pre-VSR stuff only compile when really required (since
	it's 4KiB).

2002-01-14  Jesper Skov  <jskov@redhat.com>

	* include/hal_arch.h: Moved HAL_SavedRegisters structure to
	bank variant headers. Same with HAL_THREAD_INIT_CONTEXT,
	HAL_THREAD_GET_SAVED_REGISTERS, HAL_GET_GDB_REGISTERS,
	HAL_SET_GDB_REGISTERS, CYGARC_BUS_ADDRESS, CYGARC_CACHED_ADDRESS,
	and CYGARC_UNCACHED_ADDRESS.
	* src/vectors.S: Moved exception/interrupt entry code to bank
	variant include file.
	* include/hal_var_sp.inc: Added. Contains (new) vectors.S stuff
	for SH2.
	* include/hal_var_sp.h: Added. Contains (new) hal_arch.h stuff for
	SH2 variant.
	* include/hal_var_bank.inc: Added. Contains old vectors.S stuff
	for SH3/SH4 variants.

2001-09-12  Jesper Skov  <jskov@redhat.com>

	* src/vectors.S: Don't include C intr header.

2001-09-11  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/hal_sh.cdl (CYGHWR_HAL_SH_BIGENDIAN): Set the default
	from what the platform requests, using the new
	CYGINT_HAL_SH_PLF_LITTLEENDIAN_DEFAULT CDL interface.

	* src/sh.ld: Support .rel.got input sections.

2001-09-05  Jesper Skov  <jskov@redhat.com>

2001-08-22  Gary Thomas  <gthomas@redhat.com>

	* src/redboot_linux_exec.c:

	must use diag_printf() and related functions instead.

2001-07-09  Jesper Skov  <jskov@redhat.com>

	* src/sh_stub.c: Fixed potential SH4 problem in UBC handling.

	options are always used. Other commands only affect image if
	set. This allows combined kernel&initrd images to be loaded in one
	file where the initrd address & size is already recorded at the
	start of the image.

	From YAEGASHI Takeshi <t@keshi.org> with a few changes:
	* cdl/hal_sh.cdl: Added RedBoot exec command options.

	SYM_PTR_REF. Brian Danilko spotted this.

2000-11-24  Jonathan Larmour  <jlarmour@redhat.com>

	* src/sh.ld: _reset should be adorned with CYG_LABEL_DEFN
	* src/vectors.S: CYG_LABEL_DEFN should have been used everywhere
	that CYG_LABEL_NAME was used, except for the scheduler lock which
	is special as it is defined in C as an asm alias.
	* include/arch.inc: Similarly here for symbol macros

	* include/basetype.h (CYG_LABEL_NAME): Delete. This is now obsolete.

2000-11-22  Jesper Skov  <jskov@redhat.com>

	a macro which calculates the proper values based on baud rate
	and CPU clock speed.
