	* cdl/hal_arm_ebsa285.cdl: Build redboot_cmds.c in the right place.

2000-12-04  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

	* src/redboot_cmds.c: Add prototype to remove warning.

2000-11-30  Gary Thomas  <[e-mail]>

	failing.  See kernel ChangeLog for details.  Also tidied up a
	couple of other minor details.

	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  <[e-mail]>

	* cdl/hal_arm_ebsa285.cdl: Add platform/cpu identification strings.

2000-09-06  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* include/plf_io.h (HAL_PCI_INIT): Force PCI reset, just for
	good measure.

2000-08-03  Gary Thomas  <[e-mail]>

	* 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  <[e-mail]>

	* include/pkgconf/mlt_arm_ebsa285_ram.mlt: Add heap1 section for malloc

2000-07-04  Jonathan Larmour  <[e-mail]>

	* 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  <[e-mail]>

	* include/hal_platform_setup.h: 
	'hal_dram_size' is now a properly defined variable (no more
	fixed 0x40 stuff).

2000-06-18  Gary Thomas  <[e-mail]>

	* 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_ram.mlt:
        * include/pkgconf/mlt_arm_ebsa285_rom.h:

2000-02-24  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* cdl/hal_arm_ebsa285.cdl (CYGBLD_GLOBAL_CFLAGS): Permanently set
	the -mstructure-size-boundary=8 compilation option, as required by
	software under development.

2000-02-07  Jesper Skov  <[e-mail]>

	* cdl/hal_arm_ebsa285.cdl: Use cpu option when linking.

2000-02-04  Hugo Tyson  <[e-mail]>

       * 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  <[e-mail]>

	* cdl/hal_arm_ebsa285.cdl: Implements stubs.

2000-01-31  Hugo Tyson  <[e-mail]>

	* include/hal_ebsa285.h: Correct misleading comment.

2000-01-27  Jesper Skov  <[e-mail]>

	* cdl/hal_arm_ebsa285.cdl: Moved part of stubs build rule to
	common HAL. Changed description.

2000-01-26  Jesper Skov  <[e-mail]>

	* cdl/hal_arm_ebsa285.cdl: Removed below. Target does not have
	CygMon support.

2000-01-25  Jesper Skov  <[e-mail]>

       * cdl/hal_arm_ebsa285.cdl: Added cygmon console device
       config. Added make rule for binary conversion of cygmon image.

2000-01-24  Jesper Skov  <[e-mail]>

	* cdl/hal_arm_ebsa285.cdl: Add stubs build rule.

2000-01-24  John Dallaway  <[e-mail]>

	* cdl/*.cdl:

	Remove obsolete option CYGTST_TESTING_IDENTIFIER.

2000-01-19  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* include/pkgconf/mlt_arm_ebsa285_rom.h: 
	* include/pkgconf/mlt_arm_ebsa285_ram.h: Update 'do not edit' strings.

1999-11-16  Hugo Tyson  <[e-mail]>

	* 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.
