1999-08-04  Jesper Skov  <[e-mail]>

	* src/ebsa285_misc.c (ARM_ACCESS_TYPE_x): each domain has two bits.

1999-07-26  John Dallaway  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* include/pkgconf/hal_arm_ebsa285.h: Typo in tidy up of config
	info.  Doh!

1999-07-16  Hugo Tyson  <[e-mail]>

	* include/pkgconf/hal_arm_ebsa285.h: Tidy up config info.

1999-07-15  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

	* include/hal_cache.h: Tidy up cache macros and make semantics
	better match what the GDB stubs require.

1999-07-15  Hugo Tyson  <[e-mail]>

	* include/sa-110.h: removed, it was added in error.  Its contents
	live in include/hal_ebsa285.h

1999-07-14  Hugo Tyson  <[e-mail]>
