changelog

RTEMS (Real-Time Executive for Multiprocessor Systems) is a free open source real-time operating sys

	  - irq.c:
	     * fix: remove implicit assumption that ISA interrupt vectors start
	            at 0
	     * add BSP hook to let a VME interrupt acknowledge the PCI/openpic
	       IRQ. (SEE ALSO THE ppc-sharedbsp-vme.diff patch)
	  - fix: EABI compliance; isr/exception lowlevel handlers must not
	         clobber R2 or R13
	  - fix: openpic_init was called with the polarity/senses tables
	         swapped (fixed wrong order of arguments)
	  - cosmetics: use new _read_SPRXX() _write_SPRXX() macros

2003-02-20	Till Straumann <[e-mail]>

	PR 349/bsps
	* startup/pgtbl_setup.c, startup/pgtbl_activate.c: New files
	* startup/Makefile.am, startup/bspstart.c, startup/linkcmds:
	Let the powerpc/shared (+derived) BSPs use pagetable support
   	from libcpu.

2003-02-20	Till Straumann <[e-mail]>

	PR 349/bsps
	* vme/.cvsignore, vme/Makefile.am, vme/VME.h, vme/VMEConfig.h,
	vme/vmeconfig.c: Add glue to the powerpc/shared BSP to use
	the vmeUniverse VME-PCI bridge driver.

2003-02-20	Till Straumann <[e-mail]>

	PR 349/bsps
	* console/console.c, console/uart.c, console/uart.h: implement
	IOCTLs for the serial (UART) console to install/retrieve a BREAK-IRQ
	callback.  The callback routine (if installed) is invoked from the
	UART ISR when a BREAK interrupt is detected.  This can be used
	e.g. to enforce a "hotkey" reboot a la vxWorks Ctrl-X (although we
	use the serial line break condition) NOTE: The callback runs in
	ISR context.  

2003-01-20	Joel Sherrill <[e-mail]>

	* startup/linkcmds*: Add FreeBSD sysctl() sections.

2002-12-08	Greg Menke <[e-mail]>
  
	* bootloader/head.S: Added support for optional debug via PPCbug.
	Also turn off mmu/caches for the bootstrap phase, which seems to
	cause trouble with the 603.  The cpu init functions in the bsp
	get all that stuff going properly.

2002-12-19	Joel Sherrill <[e-mail]>

	* console/console.c: Removed __assert() which conflicts with newlib.

2002-11-17	Greg Menke <[e-mail]>

	* irq/irq_init.c, motorola/motorola.c: Support for MTX603e.

2002-10-31	Joel Sherrill <[e-mail]>

	* bootloader/em86.c, console/inch.c, console/polled_io.c, irq/irq.c,
	motorola/motorola.c, pci/detect_raven_bridge.c,
	vectors/vectors_init.c: Removed warnings.

2002-07-25	Ralf Corsepius <[e-mail]>

	* bootloader/em86real.S: Fix syntax error in comment near line 1185.

2001-05-14	Till Straumann <[e-mail]>

	* bootloader/misc.c, console/Makefile.am, console/console.c,
	console/consoleIo.h, console/inch.c, console/polled_io.c,
	console/uart.c, console/uart.h, include/bsp.h, irq/Makefile.am,
	irq/irq.c, irq/irq.h, irq/irq_init.c, openpic/openpic.c,
	openpic/openpic.h, pci/Makefile.am, pci/pci.c, pci/pci.h,
	residual/Makefile.am, start/start.S, startup/bspstart.c,
	vectors/vectors.S, vectors/vectors.h, vectors/vectors_init.c:
	Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably
	with the goal to make it more flexible and reusable by other
	BSPs. The main strategies were:
	    - eliminate hardcoded base addresses; devices use offsets
	      and a BSP defined base address.
	    - separate functionality into different files (e.g. reboot from
	      inch.c to reboot.c) which can be overridden by a 'derived' BSP.
	    - separate initialization code into separate files (e.g.  PCI
	      bridge detection/initialization was separated from the more
	      generic PCI access routines), also to make it easier for
	      'derived' BSPs to substitute their own initialization code.
	There are also a couple of enhancements and fixes:
	    - IRQ handling code now has a hook for attaching a VME bridge.
	    - OpenPIC is now explicitely initialized (polarities, senses).
	      Eliminated the implicit assumption on the presence of an ISA PIC.
	    - UART and console driver now supports more than 1 port. The current
	      maximum of 2 can easily be extended by enlarging a table (it
	      would even be easier if the ISR API was not broken by design).
	    - fixed polled_io.c so it correctly supports console on COM2
	    - fixed TLB invalidation code (start.S).
	    - exception handler prints a stack backtrace.
	    - added BSP_pciFindDevice() to scan the pci bus for a particular
	      vendor/device/instance.

	* startup/linkcmds: In support of gcc 3.1, added one of more
	of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
	.gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections
	and direction of segments to memory regions may also have been
	addressed.  This was a sweep across all BSPs.
