	* src/hal_diag.c: Only avoid SERIAL0 if CYG_HAL_USE_ROM_MONITOR_CYGMON
	since we default to assuming Cygmon

	* include/variant.inc (hal_memc_init): Don't make conditional on
	ROM startup - makes sense anyway so that users can change amount
	of memory in system
	(hal_memc_init_dram): Likewise

	* include/var_arch.h (HAL_DIAG_IRQ_CHECK): Give extra return parameter
	rather than relying on this being an expression which evaluates

	This set of changes with matching ones in arch comes from Mark
	Salter's work to make jmr3904 CygMon talk Ethernet.

	* include/variant.inc: Do not re-initialize and disable all
	interrupts if RAM start, this stops networked CygMon working.
	Likewise don't re-init memory.

	* src/hal_diag.c: Add alternate hal_diag...() routines that talk
	via CygMon so that ethernet debugging works.

	* include/var_arch.h: If CYG_HAL_USE_ROM_MONITOR, export macro for
	polling unknown interrupts in CygMon, HAL_DIAG_IRQ_CHECK.
 	
1999-08-25  Nick Garnett  <nickg@cygnus.co.uk>

	* include/variant.inc: Added clock-speed dependent values for the
	DRAM DWR0 register. Values as suggested by Toshiba in PR20094.
	Added improved work-around for TOE problem suggested by Toshiba
	in PR20233.
	Some code rearranged to eliminate assembler warning messages.
	Some general tidying.

	* include/var_cache.h (HAL_ICACHE_DISABLE): Added jump to aligned
	label after disable to avoid potential race with cache. Suggested
	by Toshiba in PR20091.

1999-06-18  Nick Garnett  <nickg@cygnus.co.uk>

	* include/var_intr.h: Added TX39 specific variant of
	HAL_CLOCK_LATENCY().

	* include/var_cache.h: Added TX39 specific implementation of
	HAL_ICACHE_INVALIDATE_ALL().

1999-06-16  Jesper Skov  <jskov@cygnus.co.uk>
        CR 100804 workaround
	* src/mips_tx39.ld: Suppress .mdebug in the final output.

1999-06-02  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* src/mips_tx39.ld: 
	Add .ctors and .dtors sections as required by new compilers, but
	keep around old SORT(CONSTRUCTORS) for use by old compilers.

1999-05-27  Nick Garnett  <nickg@cygnus.co.uk>

	* src/hal_diag.c (hal_diag_write_char): Tidied away defunct code
	and made use of HAL support for user break detection and delivery.

1999-05-14  Nick Garnett  <nickg@cygnus.co.uk>

	* src/var_misc.c: Added definition of hal_interrupt_level[].

	* include/variant.inc:
	* src/variant.S:
	Added these files. They contain stuff that was previously in the
	jmr3904 platform files.

	* src/PKGconf.mak (COMPILE): Added variant.S

1999-05-13  Nick Garnett  <nickg@cygnus.co.uk>

	Imported whole directory tree into main trunk of repository.
	
1999-05-11  Nick Garnett  <nickg@cygnus.co.uk>

	* include/imp_cache.h
	* include/imp_intr.h
	* include/impl.h
	* src/imp_misc.c: 	
	* include/var_cache.h
	* include/var_intr.h
	* include/variant.inc
	* src/var_misc.c: 
	Changed references to "imp" and "implementation" to "var" and
	"variant" respectively.

	* include/var_arch.h
	File added.
	
	* include/pkgconf/hal_tx39.h: 
	* include/pkgconf/hal_mips_tx39.h:
	File hal_tx39.h renamed to match name synthesized by pkgconf.tcl.

1999-04-22  Nick Garnett  <nickg@cygnus.co.uk>

	* include/imp_cache.h: Move cache enables and disables here from
	hal_cache.h since they are tx39 specific.

1999-04-21  Nick Garnett  <nickg@cygnus.co.uk>

	* src/imp_misc.c: Added this file to contain
	hal_implementation_init().

	* src/PKGconf.mak (COMPILE): Added imp_misc.c.

1999-04-13  Nick Garnett  <nickg@cygnus.co.uk>

	* include/pkgconf/hal_tx39.h: Removed superfluous variant level
	from configuration data.
