开放源码实时操作系统源码.

2004-09-16  Gary Thomas  <[e-mail]>

	* src/var_misc.c (hal_variant_init): Remove [possibly incorrect]
	parallel port initializations - leave them to the platform.

2004-04-27  Bart Veer  <[e-mail]>

	* src/var_misc.c (hal_enable_profile_timer):
	Update this function to return the actual resolution, as 
	required by the updated gprof package

2004-04-22  Jani Monoses <[e-mail]>

	 * cdl/hal_powerpc_mpc8xx.cdl :
	 Invoke tail with stricter syntax that works in latest coreutils. 

2003-12-08  Gary Thomas  <[e-mail]>

	* cdl/hal_powerpc_mpc8xx.cdl: Define HAL_PLATFORM_CPU, based on
	actual CPU type selection - simplifies platform CDL files.

2003-10-15  Gary Thomas  <[e-mail]>

	* include/var_regs.h: Changes to allow building with GCC-3.3.x
	since the newest GAS doesn't like spaces in expressions :-(

2003-08-19  Gary Thomas  <[e-mail]>

	* src/var_misc.c: 
	* include/var_cache.h: 
	* cdl/hal_powerpc_mpc8xx.cdl: New variant 866T.

2003-07-14  Gary Thomas  <[e-mail]>

	* include/var_cache.h: Data cache flush on 850 fails when using 
	cache SPR commands, so use brute force.  This fixes some problems
	with network based debugging (RedBoot got lost because of cache
	not being flushed properly).

2003-06-24  Jonathan Larmour  <[e-mail]>

	* include/var_intr.h (cyg_hal_interrupt_acknowledge): Don't 
	inadvertently clear other interrupts when acknowledging the
	intended int. Reported by Mark Retallack.

2003-04-16  Gary Thomas  <[e-mail]>

	* src/var_misc.c (hal_variant_init): Errata setup for MPC852T

2003-03-23  Gary Thomas  <[e-mail]>

	* src/var_intr.c: 
	* include/var_intr.h: Clean up for new CDL (processor type) layout.

	* src/var_misc.c: 
	* include/var_cache.h: Better processor/variant support.

	* cdl/hal_powerpc_mpc8xx.cdl: Rearrange options to handle processor
	type more flexibly.

2003-03-06  Gary Thomas  <[e-mail]>

	* src/var_misc.c: Can only reset CPM if not relying on a ROM monitor.

2003-03-05  Gary Thomas  <[e-mail]>

	* src/var_misc.c (hal_variant_init): Reset CPM - always.

2003-03-05  Jonathan Larmour  <[e-mail]>

	* include/variant.inc: Don't let FP be set in MSR in common HAL.
	Reported by Radu Cernea <[e-mail]>

2003-01-20  Gary Thomas  <[e-mail]>

	* src/variant.S: Be careful about using QUICC functions unless that
	package is present (some MPC8xx platforms don't use it).

2003-01-18  Bart Veer  <[e-mail]>

	* src/variant.S: _mpc8xx_reset caused build failures with current
	tools.

2002-12-02  Gary Thomas  <[e-mail]>

	* src/variant.S (_mpc8xx_reset): New function, used to cause a
	hardware reset of the platform.

2002-11-25  Gary Thomas  <[e-mail]>

	* include/var_regs.h: Add CICR definitions.

2002-11-15  Gary Thomas  <[e-mail]>

	* src/var_misc.c: Change in API for profile callback.

2002-11-14  Gary Thomas  <[e-mail]>

	* src/var_misc.c: 
	* cdl/hal_powerpc_mpc8xx.cdl: Add support for profiling.

2002-11-13  Gary Thomas  <[e-mail]>

	* include/var_cache.h (HAL_DCACHE_WRITE_MODE): Define for support
	of various modes (copyback/writethru)

2002-06-27  Gary Thomas  <[e-mail]>

	* include/var_regs.h: Allow platform to override certain assumptions,
	e.g. the IMMR base, via <plf_regs.h>.

2002-06-20  Gary Thomas  <[e-mail]>

	* include/var_regs.h (MI_RPN_LPS): Fix define.

2002-05-03  Gary Thomas  <[e-mail]>

	* tests/intr0.c: Fiddle to make this test run on all current MPC8xx
	boards (the MBX is especially cranky).  The problem lies with the
	fact that the timers used to run the test are very platform specific.

2002-04-24  Jesper Skov  <[e-mail]>

	* cdl/hal_powerpc_mpc8xx.cdl: CYGPRI_KERNEL_TESTS_DHRYSTONE_PASSES
	defined.

2002-04-22  Gary Thomas  <[e-mail]>

	* tests/intr0.c: Only applicable if chained interrupts are *not*
	turned on.  Also, change setup to be a little more intuitive.

2002-04-11  Gary Thomas  <[e-mail]>

	* tests/intr0.c: Adjust counts on non-MBX platforms.  Note that
	this test is highly subjective to how the hardware is setup and
	that the test itself can't wholy determine the correct values
	to use at runtime.  The chosen ones work for known platforms.

2002-04-08  Gary Thomas  <[e-mail]>

	* include/variant.inc: Need vectors for both ROM and ROMRAM mode.

2002-01-23  Gary Thomas  <[e-mail]>

	* include/var_regs.h (CYGARC_REG_IMM_BASE): Move to match
	what EPPCbug uses (for Linux booting).

2001-08-22  Gary Thomas  <[e-mail]>

	* src/mpc8xxrev.c: Don't use printf(), but rather diag_printf().

2001-06-29  Jesper Skov  <[e-mail]>

	* src/var_intr.c: Include new arbiter header.

2001-06-28  Jesper Skov  <[e-mail]>

	* src/var_intr.c: Moved hal_call_isr to hal_misc.h in common HAL.

2001-01-31  Jesper Skov  <[e-mail]>

	* cdl/hal_powerpc_mpc8xx.cdl: Get rid of
	CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL options. They are replaced by
	the CYGSEM_HAL_DIAG_MANGLER option.

2000-11-04  Gary Thomas  <[e-mail]>

	* include/var_intr.h: Export symbols used in assembly code.

2000-06-19  Jesper Skov  <[e-mail]>

	* include/var_regs.h: 
	* include/variant.inc:

	paernt -> parent
