Intel XScale PXA255 引导Linux的Redboot 版bootloader源代码！

2000-10-20  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/mlt_arm_sa2sim_ram.mlt:
	Add heap1 section

	* include/pkgconf/mlt_arm_sa2sim_ram.h:
	* include/pkgconf/mlt_arm_sa2sim_ram.ldi:
	Regenerate

2000-09-25  Hugo Tyson  <[e-mail]>

	* include/hal_platform_setup.h (PLATFORM_SETUP1): Replace the
	invocation of INIT_BCU; premise below incorrect.  I was
	accidentally using the wrong reg (typo) for enabling access to
	p13, hence the blowup - typo fixed, cp access control reg is
	p15,c15.  We had been hitting the "process id" register - but with
	zeros anywhere that mattered.  I guess the cp access control reg
	wasn't implemented before...

2000-09-07  Hugo Tyson  <[e-mail]>

	* include/hal_platform_setup.h: Remove the invocation of INIT_BCU;
	it seems that the new simulator (2000-09-06) does not support
	this; an undefined instruction trap occurs.

2000-07-05  Jesper Skov  <[e-mail]>

	* src/sa2sim_misc.c: Added hal_default_isr to allow arch HAL
	cleanup.
	* cdl/hal_arm_sa2sim.cdl: Does not support Ctrlc.

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

	* include/pkgconf/mlt_arm_sa2sim_ram.ldi: 
	* include/pkgconf/mlt_arm_sa2sim_ram.mlt: 
	Incorporate new fixed vectors (used on all ARM platforms).

2000-03-22  Hugo Tyson  <[e-mail]>

	* simcfg/cpu.pil (retireInst): Add a convenient way to control
	whether or not the run ends with a data abort &c for running the
	exception tests.  Unset halt_on_abort to let except1 and kexcept1
	work correctly.

2000-03-21  Jonathan Larmour  <[e-mail]>

	* simcfg/sa2sim-run (PROGDIR): Escape nested quote marks for pedantic
	Solaris /bin/sh
	(PROGFILE): Likewise

2000-03-21  Hugo Tyson  <[e-mail]>

	* simcfg/sa2sim-run: Add a default to print out cpu.log file, and
	an option to turn it off.  This is mainly for the farm, of course.

2000-03-14  Jonathan Larmour  <[e-mail]>

	* simcfg/sa2sim-run: Fix help typo
	Allow Windows style paths be passed in
	Make strings more tolerant to spaces in directory names
	Diagnose a bad config file directory

2000-03-13  Hugo Tyson  <[e-mail]>

	* simcfg/sa2sim-run: Add an inference engine.  No, really, by
	default, look up the path to the test case searching for a .../bin
	and a .../etc and infer that those are where the ancillary files
	live - with special protection against reaching '/' when the
	search fails.  That search is not done if either ancillary
	location is specified at the CLI, nor if "--local" is given, in
	which case the behaviour is as before.

	The purpose of this is to allow the test farm to simply invoke
	"sa2sim-run $TESTCASE" and have it find the ancillaries from the
	testcase's tree.

	From the user's PoV, using the script from an install tree to run
	a testcase from the same install tree will acquire the ancillary
	files in that install tree, though by different means depending on
	the --local flag!

2000-03-13  Hugo Tyson  <[e-mail]>

	* cdl/hal_arm_sa2sim.cdl (CYG_HAL_STARTUP): Change this back to a
	very limited legal_values field so that the test farm tools can
	build it - you cannot set a calculated option, not even to the
	same value, but the farm tools insist on setting startup type.
	Also enhanced the description.

2000-03-09  Hugo Tyson  <[e-mail]>

	* cdl/hal_arm_sa2sim.cdl (CYGNUM_HAL_RTC_DENOMINATOR): Admit that
	we are using 1000Hz instead of 100 so that sims exec faster in
	realtime.
	(CYGNUM_HAL_RTC_PERIOD): Set to 100000 - on the assumption that
	the "Board" clock [CLK, MCLK] is 33MHz and so the CPU clock is
	100MHz (PLL does x3).  "Board" clock can go up to 100MHz.

	* include/hal_platform_ints.h (CYGNUM_HAL_INTERRUPT_RTC): Change
	over to using the PMU interrupt CYGNUM_HAL_INTERRUPT_PMU_CCNT_OVFL
	for the system clock instead.

	* src/sa2sim_misc.c (hal_clock_initialize):
	(hal_clock_reset):
	(hal_clock_read): Use the Performance Monitor's clock instead of
	bangirq.pil; might as well leave bangirq.pil as is since it does
	no harm (except wasting simulated electricity) and it's good
	illustration of how to use a banger.
	(hal_IRQ_handler): remove workaround for limitations of banger.
	(hal_interrupt_mask):
	(hal_interrupt_unmask):
	(hal_interrupt_acknowledge): Take care not to screw up the PMU
	when enabling/disabling its interrupts.


2000-03-08  Hugo Tyson  <[e-mail]>

	* cdl/hal_arm_sa2sim.cdl: Arrange also to build bangfiq.cdl in the
	install place or whatever it is.  Just copied the rule for bangirq.

2000-03-08  Hugo Tyson  <[e-mail]>

	* simcfg/bangfiq.pil (bangFiq.value): new file: just set the fiq
	level high so that no FIQ occurs - it can float otherwise.

	* simcfg/bangirq.pil (duration): duration is now 300 so that the
	CPU has time to decode the interrupt before it disappears.

	* src/sa2sim_misc.c (hal_IRQ_handler): Take out the workaround for
	the previous sim bug, and add a workaround for the non-latching
	nature of the IRQ source register (at least with bangirq.pil as
	the interrupt source).

2000-03-02  Jonathan Larmour  <[e-mail]>

	* cdl/hal_arm_sa2sim.cdl: Use install -c for compatibility with BSD
	hosts

2000-02-29  Jonathan Larmour  <[e-mail]>

	* cdl/hal_arm_sa2sim.cdl: Use install rather than cp to install the
	files, which allows us to be sure they have the correct mode.

	* simcfg/sa2sim-run: Remove dependency on which by adding "findonpath"
	shell function. Also work out relative directories correctly if we
	were invoked from the PATH

2000-02-28  John Dallaway  <[e-mail]>

	* cdl/hal_arm_sa2sim.cdl:

	Give a CYG_HAL_STARTUP a constant calculated value to faciliate
	correct presentation in the GUI config tool.

2000-02-25  Jonathan Larmour  <[e-mail]>

	* simcfg/sa2sim-run: To make jld happy, fall back on bash's "type -p"
	if "which" doesn't exist

2000-02-24  Jonathan Larmour  <[e-mail]>

	* simcfg/sa2sim-run: Cope with path names with spaces on NT, and
	the quirks of the NT simulator

2000-02-23  Jonathan Larmour  <[e-mail]>

	* simcfg/sa2sim-run: New script (copied into install/bin) to make
	running the sim easier

	* simcfg/README: Clarify build instructions for sh vs. csh

	* cdl/hal_arm_sa2sim.cdl: Add custom make rules to copy cfg files
	to install/etc, and rebuild lilmon.elf into install/bin

2000-02-21  Hugo Tyson  <[e-mail]>

	* cdl/hal_arm_sa2sim.cdl: Add ugly-named but WCYD?  cdl_option
	CYGHWR_TARGET_SIMULATOR_NO_GDB_WORKING to enable testcase control
	variable cyg_test_is_simulator to be defaulted to true *if* you
	can't do it via GDB at this time. (see infra/.../tcdiag.cxx)

	* simcfg/cpu.pil (retireInst): Make the output to the cpu.log more
	controllable.  General tidyup for farm use.

	* simcfg/bangirq.pil (period): Comment out all the output so we
	get no bangirq.log by default - for the farm.

2000-02-18  Hugo Tyson  <[e-mail]>

	New files, to keep safe the config/control files and "boot" image
	for the simulator:
	* lilmon/COMPILECOMMAND
	* lilmon/README
	* lilmon/lilmon.elf
	* lilmon/lilmon.lnk
	* lilmon/lilmon.s
	* simcfg/README
	* simcfg/bangirq.pil
