-
-	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

-	new routines.
-
-	* include/halboot.si: 
-	Remove N/A code that I was just storing here, and install the real

-
-1999-02-01  Hugo Tyson  <hmt@cygnus.co.uk>
-

-
-	* 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.

+2002-10-19  Jonathan Larmour  <jifl@eCosCentric.com>
 
-	* 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.
+	Patch from Jiri Gaisler:
+	* cdl/hal_sparc_erc32.cdl: -msoft-float should be used in global
+	CFLAGS, not just locally.
+	* include/hal_diag.h: Fix UART TX masks.
 
-	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.
+2002-03-14  Jiri Gaisler  <jiri@gaisler.com>
 
-	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.
+	* Initial version based on the SPARClite SIM HAL.
 
-	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.
