+1999-04-08  John Dallaway  <jld@cygnus.co.uk>
+
+	* include/pkgconf/*.ldi: Revised SECTION_* macro arguments to
+	avoid padded output sections (PR 19787)
+
+1999-04-07  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* src/hal_priv.c: Remove bogus FIX ME; it wasn't true.
+
+1999-03-16  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* include/halboot.si: Add a dummy LED macro for debug in the
+	vectors.S; correct a scary line length.
+
+1999-03-04  Gary Thomas  <gthomas@cygnus.co.uk>
+
+	* include/pkgconf/hal_sparclite_sim.h: Take out DEVICES dependencies.
+
+1999-03-04  John Dallaway  <jld@cygnus.co.uk>
+
+	* include/pkgconf/*.ldi: give all LDI files unique names so
+        that they can co-exist in an eCos build tree (PR 19184)
+	* include/pkgconf/*.mlt: give all MLT files unique names so
+        that they can co-exist in an eCos build tree (PR 19184)
+
+1999-02-25  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	These log entries from 1999-02-22 to 1999-02-24 were executed in
+	a branch; this change is a merge of that branch into the trunk.
+
+	(1999-02-23  John Dallaway  <jld@cygnus.co.uk>)
+
+	* include/pkgconf/hal_sparclite_sim.h: New rules
+	CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_GDB
+	CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_SERIAL_RS232_COMMON
+
+	(1999-02-22  Hugo Tyson  <hmt@cygnus.co.uk>)
+
+	* src/hal_priv.c (hal_board_prestart, hal_board_poststart): 
+	Shut down the erc32 watchdog in and enable interrupts in these two
+	new routines.
+
+	* include/halboot.si: 
+	Remove N/A code that I was just storing here, and install the real
+	vector instructions in this fragment; there be cache-wangling to
+	do in hardware cases either side of the vector installation.
+
+1999-02-20  Jonathan Larmour  <jlarmour@cygnus.co.uk>
+
+	* include/hal_xpic.h: 
+	Rename CYG_VECTOR_* -> CYGNUM_HAL_INTERRUPT_*
+
+	* src/hal_priv.c:
+	Add a FIX ME
+
+1999-02-08  John Dallaway  <jld@cygnus.co.uk>
+
+	* src/sim.ld: Remove platform-specific linker script for
+        MLT compliance.
+
+	* src/PKGconf.mak: Remove build rules for sim.ld.
+
+	* include/pkgconf/ram.*: Add MLT save file and and linker
+        script fragment for RAM startup.
+
+1999-02-01  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* include/halboot.si: 
+	New file: performs platform-oriented setup of RAM and cache
+	controllers, and quietens any interrupt sources.
+
+	* include/pkgconf/hal_sparclite_sim.h: 
+	Correct comments/CDL description of sim invocation.
+
+1999-01-28  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* include/hal_cache.h: NEW FILE to this directory; moved here from
+	the sparclite/arch tree; cache control is very much board-specific
+
+	* include/hal_clock.h: NEW FILE to this directory; it was a part
+	of hal_intr.h, but is now here because the clock is target determined.
+
+	* include/hal_xpic.h: NEW FILE to this directory; it was a part of
+	hal_intr.h, but is now here because the detail of interrupot
+	control is target determined.
+
+	* src/hal_priv.c: NEW FILE to this directory; it was a part
+	of hal_intr.h, but is now here because the clock is target
+	determined, and it's the clock that needs a local variable.
+
+	* src/PKGconf.mak (COMPILE): compile it.
+	
+
+1999-01-26  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* src/sim.ld: 
+	Add copyright notice.  (Though these files will later be generated
+	by a tool and so not copyright, these default setups are.)
+
+1999-01-22  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* src/sim.ld: 
+	Remove some bogus comments.
+
+1999-01-21  Jonathan Larmour  <jlarmour@cygnus.co.uk>
+
+	* src/sim.ld: 
+	Remove all traces of non-CYG_KERNEL_USE_INIT_PRIORITY code
+
+1999-01-21  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* src/sim.ld: 
+	Align bss and rom/ram_data starts and ends by 8 bytes to permit
+	fast copy routines.
+
+1999-01-19  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	Modified files in arch:
+	* include/hal_arch.h
+	* include/hal_intr.h
+	* src/PKGconf.mak
+	* src/context.S
+	* src/hal_intr.c
+	* src/vec_ivsr.S
+	* src/vec_xvsr.S
+	* src/vectors.S
+
+	New files in arch:
+	* src/hal_boot.c	(bss initialization, constructors &c)
+	* include/hal_cache.h	(empty but required header)
+
+	Modified files in sim:
+	* include/hal_diag.h
+
+	Lots more progress; essentially, everything now works.
+
+	Simulator's treatment of stdio is poor though, it doesn't work
+	under pkgtest.  This has been slowing me up.
+
+1999-01-14  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* ecc/ecc/hal/sparclite/...:
+
+	Initial checkin of SPARClite HAL; it doesn't work yet, except the
+	most trivial of tests - timer and interrupt manipulation stuff is
+	entirely absent.
+
+	Here's some documentation of the initial checkin tree; this will
+	change, as platform dependent stuff moves correctly into the sim
+	or <board> directories.
+
+	arch/current/include:
+		basetype.h	nothing much here.
+		vectors.h	definitions of symbols shared between the
+			various vector code assembler files, can be
+			included in both C and assembler.
+		hal_intr.h	various macros for clock and interrupt
+			control plus the eCos vector numbering scheme; we
+			map thus:
+			what	SPARC trap type	    eCos vector numbers
+			-----------------------------------------------
+			(not used)   ---                0	
+			interrupts (17-31)		1-15
+			user traps (128-255)		16
+			exceptions (1-9,36==4)		17-25
+			others	   (10,?)		26
+			-----------------------------------------------
+			Trap types 5 and 6 which would be eCos vectors 21
+			and 22 are handled in the trampoline code in
+			file src/vectors.S
+		hal_arch.h	definition of a thread context, plus
+			macros for thread switching and the like.  Some
+			ancillary bit twiddling macros and cache barriers
+			too.
+
+	arch/current/include/pkgconf:
+		hal_sparclite.h 	pkgconf config/header file.
+	
+	arch/current/src:
+		vectors.S	boot-up stuff, trampoline code that hangs
+			on the interrupt/trap vector, handlers for window
+			under/overflow.  Saves some state in registers
+			then jumps to the interrupt or exception VSR
+	   		respectively.
+			Also instantiates the VSR table.
+		vec_ivsr.S	the default interrupt VSR; it establishes
+			a C calling environment (ie. anticipates a window
+			overflow) then locks the scheduler, calls the ISR
+			with appropriate arguments, and then interrupt_end()
+			before undoing that environment, anticipating
+			window underflow and returning to the interrupted
+			instruction.
+		vec_xvsr.S	the default exception AKA trap VSR; does
+			the same as the interrupt one but without the
+			scheduler lock or interrupt end.
+		hal_intr.c	instantiates the ISR table used by the
+			code above.
+		context.S	context switch code, saves and loads up a
+			whole register state, coroutine or longjump-like.
+		icontext.c	initializes a context to "jump" to in
+			context.S at the birth of a new thread.
+
+	sim/current/include:
+		hal_diag.h	macros to deal with debugging output via a
+			fake serial device of some kind; initially empty,
+			but definitely board/sim dependent.
+
+	sim/current/include/pkgconf:
+		hal_sparclite_sim.h 	pkgconf config/header file.
+
+	sim/current/src:
+		sim.ld		linker script bits for "sim" target.
