	* src/hal_misc.c: Clean up list of included files.  <hal.h>
	now provides target and platform specifics.

	* src/hal_intr.c: CYGFUN_HAL_COMMON_KERNEL_SUPPORT should only
	be defined if CYGPKG_KERNEL is defined.  This needs to be fixed
	in a more generic fashion when full CDL becomes available.

	* src/vectors.S: Exception and interrupt handling were enabling
	CPU interrupts when it wasn't safe nor warranted.

1999-08-16  Jesper Skov <jskov@cygnus.co.uk>
	From Bob Koninckx <bob.koninckx@mail.mech.kuleuven.ac.be>

	* src/ppc_stub.c (__clear_single_step): Clear irq_state to prevent
	interrupt avalanche.

1999-06-29  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/hal_intr.h (CYGNUM_HAL_EXCEPTION_DATA_ACCESS): Define
	this for handling MACHINE_CHECK if an MPC860 - it never generates
	ISI nor DSI exceptions, only machine check.  This allows libc to
	catch SEGVs from this unexpected quarter.

1999-06-28  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/ppc_regs.h: Add proper definitions of timebase regs.

	* tests/intr0.c: Add some useful debugging printouts and recording
	of state, and make more platform-portable; the rate of PTA is not
	always 1:32 wrt the timebase.

1999-06-27  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/vectors.S (_start): Call platform dependent IRQ setup (see
	next note).

	used to setup whatever is necessary to handle interrupts.
	Add basic "wiring" of CPM to SIU interrupts.

	* include/hal_intr.h: Fix CPM interrupt macros - control register
	is 32 bits, not 16.

1999-06-24  Jesper Skov  <jskov@cygnus.co.uk>

	* misc/CPUMask8xx.c: Added.

1999-06-24  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/hal_misc.c (cyg_hal_exception_handler): If the decrementer
	has underflowed when we are returning from an exception, then we
	reset it here; this is harmless if all is well, and required if
	the QUICC-equipped MPC860 is getting confused about interrupts
	following an exception.  Only in QUICC configurations.

1999-06-22  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/vectors.S (_start): Support breaking back into the stub ROM
	when we see a breakpoint, if RAM start and RAM-based vectors for
	the stub.  Rather than using a direct jump, instead skip copying
	the program exception vectors - leave the stub's vec in place.
	Controlled by CYGPRI_STUBROM_HAS_RAM_VECTORS, which varies from
	platform to platform.

1999-06-18  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/hal_misc.c (hal_enable_caches): Change the configuration,
	the better to accommodate differing platform requirements viz a
	viz cache enabling and so on.

1999-06-17  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/vectors.S (CYG_MSR): define correctly for copying vectors,
	even if ROM start.  Complete system init for ROM start.

1999-06-15  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/ppc.inc: Add definitions of FUNC_START and FUNC_END.
	They are needed by platform code.

	* src/vectors.S: Remove definition of FUNC_START.

1999-06-11  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/vectors.S (_start): remove some platform-conditional
	initialization code; it is now in hal_hardware_init in the
	platform HAL.

	* src/hal_misc.c: remove very-platform-conditional definition of
	memory descriptor table - it is now in platform HALs.
	
	* include/ppc_regs.h: simplify definition of CYGARC_REG_IMM_BASE.

	* include/hal_cache.h (CYGARC_MEMDESC_CACHE): ...and other
	macros... add support for external definitions of memory
	descriptor table used in platform-specific initialization of MMU.

1999-06-10  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/vectors.S (_start): Add better support for various startup
	options, including CygMon loading.

	* src/PKGconf.mak (COMPILE): remove quicc_smc.c; it has been
	reorganized and renamed into the FADS component.

	* include/quicc_smc.h, src/ppc_860.h, src/quicc_smc.c: removed;
	reorganized and renamed into the FADS component.

	* src/hal_misc.c (hal_idle_thread_action): Add some useful
	debugging for interrupt/clock of the MBX860/PPC860; normally
	disabled, so no effect on code.

	* include/ppc_regs.h: Different default value for
	CYGARC_REG_IMM_BASE if MBX board (ie. the way CygMon sets it up).
	This is a temporary measure.

1999-06-08  Jesper Skov  <jskov@cygnus.co.uk>

	* include/hal_intr.h: 
	* src/vectors.S (hal_vsr_table):
