2004-05-07  Mark Salter  <msalter@redhat.com>

	* src/vectors.S (reset_vector): Add some debug-only led setting code.

	* src/redboot_linux_exec.c: Rename auto-variable for clarity.

2004-04-02  Mark Salter  <msalter@redhat.com>

	* include/fr-v.h: Add defines for baud clock prescaler.

2004-03-29  David Woodhouse  <dwmw2@redhat.com>

	* src/vectors.S: Fix check for PDM bits in potential resume.

2004-01-29  David Woodhouse  <dwmw2@redhat.com>

	* src/vectors.S: Handle resume from sleep modes.

2003-12-22  David Woodhouse  <dwmw2@redhat.com>

	* src/redboot_linux_exec.c: Fix argv parsing for exec() command.

2003-12-03  David Woodhouse  <dwmw2@redhat.com>

	* include/hal_diag.h src/hal_diag.c: Move support for the built-in
	16550-like chips found on all known implementations of these CPUs 
	into the arch directory to avoid duplication.
	* include/fr400.h include/fr500.h include/fr-v.h: Likewise many
	other register definitions.
	* src/hal_breakpoint.c: Likewise breakpoint/watchpoint stuff.
	* cdl/hal_frv.cdl: Changes to reflect the above.
	
2003-12-03  David Woodhouse  <dwmw2@redhat.com>

	* src/vectors.S: Install exception vectors if not defined
	CYGSEM_HAL_USE_ROM_MONITOR. This way, syscalls and GDB work
	in RAM RedBoot.

2003-11-13  David Woodhouse  <dwmw2@redhat.com>

	* cdl/hal_frv.cdl, src/redboot_linux_exec.c: Exec command.
	
2003-11-13  David Woodhouse  <dwmw2@redhat.com>

	* src/vectors.S, src/context.S, include/hal_arch.h: Save extra GP
	and FP regs only when they're actually available on this CPU, if
	multiple CPUs are supported.
	
2003-11-13  David Woodhouse  <dwmw2@redhat.com>

	* cdl/hal_frv.cdl: Disable use of break insn for trap. Remove 
		seemingly unnecessary option for hardware debugging.
	* include/hal_arch.h: Add _PSR_CM bit. It's not always hardwired.
	* src/hal_mk_defs.c: Ditto. Rename _HAL_THREAD_INIT_CONTEXT
	* src/vectors.S: Some ifdef cleanup, enable _PSR_CM
	
2003-01-31  Mark Salter  <msalter@redhat.com>

	* src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
	handle exit.

2002-04-15  Jonathan Larmour  <jlarmour@redhat.com>

	* src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
	__do_syscall.

2001-12-10  Richard Sandiford  <rsandifo@redhat.com>

	* src/vectors.S (save_state): Remove unnecessary DDR diddling when
	handling breaks.  Use BPCSR rather than BPCSR-4 as the break address.
	(restore_state): Take two new arguments: the register that the
	PC should be loaded into, and the argument to the rett instruction.
	(_break): If handling a break instruction, return to the following
	instruction using a normal "ret".  Ignore other kinds of break if
	they were triggered when traps were disabled; assume that an
	interrupt or exception handler has triggered a stack watchpoint
	accidentally.  Correct GP calculation.  Return using "rett #1"
	rather than "rett #0".

2001-11-28  Hugo Tyson  <hmt@redhat.com>

	* src/vectors.S (_vectors): if defined(CYGPKG_HAL_FRV_FRV400) &&
	defined(CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS), add macro break_VSR
	to create a VSR entry which leaps to _break; rearrange the
	initialization of the VSR table so that the counts are correct;
	use break_VSR in slot 255; define _break which calls break_handler()
	much akin to exception handler().	

	Note that there is no need to define CYGSEM_HAL_FRV_HW_DEBUG for
	the FRV_FRV400 target; while we do use Hardware Debug, we don't
	use *that* sort of hardware debug, specifically we do not use
	hardware single-step, because it breaks as soon as we exit debug
	mode, ie whilst we are still within the stub.  But vectors.S does
	the same tidy-up of machine state, conditioned on FVR400 instead.

2001-10-17  Gary Thomas  <gthomas@redhat.com>

	* src/frv_stub.c: Slight cleanup - only need |VLIW|+1 possible
	breakpoint locations.

2001-10-16  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (_exception_return): Remove *bad* workaround code
	now that single step VLIW works properly.

	* src/frv_stub.c (__clear_single_step): 
	(__single_step): Restructure to support VLIW sequences.

2001-10-15  Gary Thomas  <gthomas@redhat.com>

	* include/hal_arch.h: Remove [bogus] CYG_HAL_TABLE macros since 
	the common ones work fine on this architecture.

	* src/vectors.S: 
	* src/frv_stub.c: 
	* cdl/hal_frv.cdl: Add CDL to describe various [hardware] debug
	options.

2001-10-01  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S: [FRV400] can't return from exception to a packed
	instruction - this yields illegal instruction.
	
2001-10-11  Gary Thomas  <gthomas@redhat.com>

	* cdl/hal_frv.cdl: 
	* include/basetype.h: 
	* include/hal_arch.h: 
	* include/hal_intr.h: 
	* include/frv_stub.h:
