1999-10-22  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/hal_diag.c (hal_diag_write_char): Call new hal_stub.h macro
	CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION() instead of simply disabling
	interrupts, ditto for enable.  This provides atomicity wrt single
	stepping and watching variables when this code to output a whole
	GDB $O packet is entered.

1999-09-20  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/pkgconf/hal_powerpc_mbx.h:
	(CYGHWR_HAL_POWERPC_MBX_BOOT_32BIT_FLASH) new config option to

1999-09-09  Gary Thomas  <gthomas@cygnus.co.uk>

	* include/pkgconf/hal_powerpc_mbx.h (CYGHWR_HAL_POWERPC_MBX_BOARD_SPEED): 
	Rename CDL option to avoid a name clash.

1999-07-27  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/mbx.S: Fix typo in PLL setup value.  Reported from the net.

1999-06-28  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/hal_diag.c (hal_diag_init): Fix a "default type" warning.

1999-06-28  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/hal_diag.c (hal_diag_write_char): Only gobble the GDB ACK
	characters if there is no pre-ISR polling call to look for ^C
	chars to interrupt the prog.  (CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT
	- should not be enabled if devices are in use)

1999-06-28  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/mbx.S (__upmtbl_start): We do not trust rewriting the UPMs
	for DRAM timing whilst running out of that very DRAM.  So only
	init UPMs in ROM start (including when making a stub rom).

1999-06-27  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/hal_diag.c: Support buffering of diagnostic data for later
	display.  Controlled by CYGDBG_DIAG_BUF.  Also, turn on code to
	handle GDB ACK characters when stubs are enabled.

1999-06-25  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/mbx.S (__upmtbl_start): depending on CYG_HAL_ROM_MONITOR, we
	use the OLD TABLES if making a stub rom.  For greatest commonality
	of startup code between RAM startup development binaries and ROM
	startup "product" binaries we completely re-initialize the UPMs
	that control DRAM timing even in RAM start when executing out of
	that very DRAM.
	
	It appears that it is OK to rewrite the UPMs with the new timing
	data when already running with the old timing data, but not OK to
	update from new to new.  So we use the old timing data when
	building stubs.

	An alternative would be to conditionally not perform the UPM
	initialization in RAM startup, but that would weaken the testing
	value of RAM startup programs.

1999-06-24  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/mbx.S (__upmtbl_start): Use the new tables recently supplied
	by email from Motorola; without them, the cache-line-zero
	operation only zeros 12 bytes rather than 16.  [PR 20226]

1999-06-24  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/plf_stub.h (HAL_STUB_PLATFORM_INIT_BREAK_IRQ): Define
	this (empty) for it is required if HAL_DEBUG_GDB_BREAK_SUPPORT is
	enabled.  Improve HAL_STUB_PLATFORM_SET_BAUD_RATE.

1999-06-18  John Dallaway  <jld@cygnus.co.uk>

	* include/pkgconf/mlt_powerpc_mbx_rom.mlt: 
	* include/pkgconf/mlt_powerpc_mbx_ram.mlt:
	Fix MLT save files to match the default linker script
	fragments.

1999-06-18  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/pkgconf/mlt_powerpc_mbx_rom.mlt: 
	* include/pkgconf/mlt_powerpc_mbx_ram.mlt:
	Initial attempt at getting these to match the reality of the
	linker script fragment; we'll have to see whether they're right.

1999-06-18  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/mbx.S: Data cache setup in hal_hardware_init: set
	force-writethrough mode and explicitly disable little-endian swap
	mode, whatever _that_ is.  Force-writethrough is required if you
	are to enable the data cache, it crashes otherwise.  Cause
	unknown, could be the memory system doesn't support whatever
	access regime is used, or caching problems with loading code
	through the stubs?  In any case, this is a fine workaround.
	
	* src/hal_aux.c (CYGARC_MEMDESC_TABLE): Enable caching of the ROM;
	seems to do no harm, and helps ROM-based performance.

1999-06-18  Jesper Skov  <jskov@cygnus.co.uk>

	* include/pkgconf/hal_powerpc_mbx.h: Fixed CDL description.

1999-06-17  Hugo Tyson  <hmt@cygnus.co.uk>

	* misc/stubrom.perm: New file: a perm for creating an eCos stub
	ROM for the MBX.  Pro tem, ^C to break is not supported, so the
	feature must remain disabled.

	* include/plf_stub.h (HAL_STUB_PLATFORM_INIT): Diddle the LEDs if
	ROM start to distinguish eCos stub ROM from CygMon ROM from eCos
	app running/internal stubs.

1999-06-17  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/pkgconf/mlt_powerpc_mbx_rom.ldi: Move RAM usage in ROM
	startup to 2000 so that we can build stubs that don't fight with
	RAM started apps' RAM use from 10000.

1999-06-17  Hugo Tyson  <hmt@cygnus.co.uk>

	* tests/PKGconf.mak: New file, to build that below.

	* tests/mbxtime.cxx: New file, a simple test of the system timer
	for a human to check it's roughly seconds.

	* include/pkgconf/mlt_powerpc_mbx_rom.ldi: ROM startup supported.

	* include/pkgconf/hal_powerpc_mbx.h
	(CYGHWR_HAL_POWERPC_MBX_BOARD_SPEED): Add this config option to
	select 40MHz or 50MHz system clock speed.

	* src/mbx.S (hal_hardware_init): Complete system init for ROM
	start; move return address to inside the ROM from wherever we
	booted.  Proper board clock speed selection.

	* src/hal_diag.c (hal_diag_write_char_serial): Do not encode
	packets for GDB if using ROM start.

	* src/hal_aux.c (CYGARC_MEMDESC_TABLE): Map the ROM correctly so
	that ROM start works.

1999-06-15  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/mbx.S (hal_hardware_init): Add full ROM-type startup code
	and some useful LED-diddling routines and macro, to assist in
	debugging ROM startup.
	
	* src/hal_aux.c (CYGARC_MEMDESC_TABLE): Enable memory mapping to
	the LED control register so that we can treak them with mem mgt
	enabled ie. in a normal execution context.	

1999-06-11  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/mbx.S (hal_hardware_init): Set up the base address of the
	control registers in IMMR to 0xff000000 (as defined in arch).
	Turn off external interrupts, initialize the decrementer.

	* src/PKGconf.mak: Build the new file.

	* src/hal_aux.c (CYGARC_MEMDESC_TABLE): New file, to define this
	object for per-platform table-driven memory map initialization.
	The table used to be in hal_misc.c in the architectural HAL; this
	is platform dependent so better and cleaner here.

1999-06-10  Hugo Tyson  <hmt@cygnus.co.uk>

	* ChangeLog: Component created, based partly on the FADS work and
	on CygMon's serial IO code for the MBX860, to support the Motorola
	MBX860 development board.  Actual serial support lies in
	neighbouring component HAL_QUICC [hal/powerpc/quicc/...]
