	* src/plf_serial.c: I/O channel data can't be constant - contains
	timeout information which can be changed.

2001-10-31  Jonathan Larmour  <[e-mail]>

	* cdl/hal_mips_vr4300_vrc437x.cdl: Indicate support of variable baud
	rates.

2001-10-30  Nick Garnett  <[e-mail]>

	* include/platform.inc:
	Added local version of hal_intc_decode to make chaining work
	correctly.
	
	* include/plf_intr.h:
	Added local version of HAL_TRANSLATE_VECTOR() to make chaining
	work correctly.

2001-10-24  Nick Garnett  <[e-mail]>

	* include/hal_diag.h: Fixed problem with support for virtual
	vector diagnostics.

	* include/platform.inc:
	Modify the ROM and ROMRAM version of hal_mon_copy_trampoline to
	copy the utlb trampoline to 0xa0000080 as well as 0xa0000000. This
	is necessary on 64 bit machines to catch 64 bit TLB exceptions.

2001-09-17  Nick Garnett  <[e-mail]>

	* src/plf_misc.c:
	Added ISR for dealing with spurious interrupts from the VRC437X.
	Added PCI initialization routine.

	* src/platform.S: Change PCI IO base address setup to a more
	explicit value.

	* include/plf_io.h: Adjust PCI IO and memory base addresses to
	match the actual hardware setup.
	Add explicit PCI initialization routine.

	* include/platform.inc: Install bus error VSR in non-stub
	configurations too.

2001-09-07  Nick Garnett  <[e-mail]>

	This package is newly created to contain code that is common to
	all VRC437X platforms. Most of the contents is derived from the
	original VRC4373 package. All ChangeLog entries other than this
	one were made when the files were in that package.  This ChangeLog
	entry describes any major changes that have occured to the files
	during the move.

	* include/platform.inc:
	Converted INITIAL_SR to INITIAL_SR_PLF to work with architecture
	and variant HALs.

	* src/platform.S: Added VRC4375 setup.
	
	* src/plf_serial.c: File added to implement serial IO in a vector
	compatible manner.
		
	* cdl/hal_mips_vr4300_vrc437x.cdl: Generic configuration for all
	targets added. Platform specific configuration moved out to
	specific packages.
	
	* include/hal_diag.h:
	* include/plf_cache.h:
	* include/plf_intr.h:
	* include/plf_io.h:
	* include/plf_stub.h:
	* include/plf_z8530.h:
	* misc/stubrom.perm:
	* src/hal_diag.c:
	* src/plf_misc.c:
	* src/plf_stub.c:
	* src/pmon.S:
	Files move with minor changes only from original VRC4373 package.
