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.

2000-02-18  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]

       * 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

	* 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.

1999-10-05  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.

	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

	* 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):

	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>
