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

2005-11-08	Till Straumann <[e-mail]>

	PR 845/bsps
	* startup/bspstart.c, start/start.S: setup BATs prior to attempting any
	device access - missing BAT mappings were probably the reason for the
	MMU malfunction assumption. Enabled MSR_DR.

2005-11-08	Till Straumann <[e-mail]>

	PR 837/bsps
	* startup/bspstart.c, pci/detect_raven_bridge.c: Make sure
	exceptions_in_RAM flag is set prior to initializing exception
	handling. Keep MCP disabled for memory probes :-( (the raven would
	otherwise fault on PCI config space access to empty slots).

2005-11-07	Till Straumann <[e-mail]>

	PR 834/bsps
	* vectors/vectors.S: reload stack pointer/R1 from exception frame
	instead of adding static offset.

2005-10-06	Till Straumann <[e-mail]>

	PR 833/bsps
	* irq/irq_asm.S: Currently, all (new exception) BSPs explicitely enable
	the FPU across the user ISR but DONT save/restore the FPU context.
	Any use of the FPU fron the user handler (e.g., due to GCC
	optimizations) result in corruption. The fix results in an exception
	in such cases (user ISR must explicitely save/enable/restore FPU).

2005-09-01	Joel Sherrill <[e-mail]>

	* include/bsp.h: This file is only to be used by BSPs with the new
	interrupt API so checking for USE_ENHANCED_INTR_API is not needed.

2004-11-23	Richard Campbell <[e-mail]>

	* startup/bspstart.c: Removed mpc824x conditionals around call to 
	L1_caches_enables, conditionals are now in mmuAsm.S.
 	* vme/VMEConfig.h: Set up VME A16, A24 and A32 windows at different 
	locations for mvme2100.
	* vme/vmeconfig.c: Fixed spelling.

2004-11-10	Richard Campbell <[e-mail]>

	bootloader/pci.h, console/console.c, console/inch.c,

	startup/bspstart.c, vectors/vectors_init.c, vme/vmeconfig.c: Add
	MVME2100 BSP and MPC8240 support. There was also a significant amount
	of spelling and whitespace cleanup.
	* tod/.cvsignore, tod/Makefile.am, tod/todcfg.c: New files.

2004-09-27      Greg Menke <[e-mail]>

	PR 606/bsps
	* bootloader/pci.c: Fixed IO remapping so buses >= 1 are remapped.
	Reduced PCI space to match bat2.  Fixed incorrect region size
	calculation in pci_read_bases.  Set PCI latency timers to known
	sane values.  Changed bridge PCI settings to minimum sane instead
	of whatever sounded neat in the PCI spec.  Force pf regions to
	memory mapped to preserve byte access.

2003-07-16      Greg Menke <[e-mail]>

	PR 432/bsps
	* bootloader/pci.c: Re-instated code that prevents remapping small
	IO regions, which if remapped would cause i8259 registers to move
	out from under the #define'd base addresses.
	* startup/bspstart.c: Reduced BAT2 PCI memory allocation to 256
	megs, I incorrectly had extended it which would cause problems with
	PCI devices that defined prefetchable memory.
	
2003-06-13	Greg Menke <[e-mail]>

	PR 405/bsps
	* bootloader/pci.c: Added support for configuring devices for pci
	busses > 0
	* pci/pci.c, pci/pci.h: Added FixupPCI() to store vectors in the
	INTERRUPT_LINE register of pci devices any # of hops away
	from the host processor.
	* motorola/motorola.c, motorola/motorola.h: Added interrupt
	routing tables in support of FixupPCI.  This is board-specific,
	each board will have to supply information for FixupPCI() to do
	anything for it.
	* startup/bspstart.c: Extended bat2 to cover entire PCI address space.
	* irq/irq.c, irq/irq.h: Added support for shared interrupts.
	Existing single hander vectors are undisturbed, a new function
	added to allow adding/removing handlers from a vector.

2003-06-13  Till Straumann <[e-mail]>

	PR 415/bsps
	* include/bsp.h, pci/detect_raven_bridge.c, startup/bspstart.c:
	Support enabling MCP exceptions on the host bridge. This can
	be used for memory probing on the VME bus.

2003-04-15	Joel Sherrill <[e-mail]>

	PR 386/bsps
	* vme/vmeconfig.c: Removed declaration of _BSP_vme_bridge_irq.

2003-04-15	Joel Sherrill <[e-mail]>

	PR 386/bsps
	* vme/vmeconfig.c: Removed declaration of _BSP_vme_bridge_irq.

2003-04-10  Till Straumann <[e-mail]>

	PR 379/bsps
	* console/polled_io.c: libcpu provides 'printk' already.
	Therefore, the implementation in this file was removed (still
	used for the bootloader, though).  It now provides BSP_output_char()
	for libcpu's printk().
	* console/uart.c, console/uart.h: BSP_output_char_via_serial()
	prototype changed to match the BSP_output_char_function_type.  Note
	that the motorola BSPs use polled-io for the output_char routine, not
	the uart.c version. The latter can be used be other BSPs however
	(e.g. SVGM).
	* console/console.c, console/consoleIo.h, console/polled_io.c,
	irq/irq_init.c, openpic/openpic.c, pci/detect_raven_bridge.c:
	Unfortunately, the supported 'printk' format string subset of the
	polled-io and libcpu implementations are different - hence, a few
	format strings in the ppc/shared BSP were changed.

2003-04-10	Joel Sherrill <[e-mail]>

	PR 383/bsps
	* irq/irq.c: Fix bug introduced by conflicts in previous patches.

2003-03-25  Till Straumann <[e-mail]>

	PR 360/bsps
	* irq/irq.c, irq/irq_init.c, openpic/openpic.c, openpic/openpic.h:
	BSP code had set the task priority register multiple times of
	the OpenPIC instead of setting the individual source priorities.
	This patch adds openpic_get_source_priority() and
	openpic_set_source_priority() calls and lets IRQ management code
	use them.

2003-03-25  Till Straumann <[e-mail]>

	PR 349/bsps
	* irq/irq.c, vme/VME.h, vme/vmeconfig.c: Fixes library dependency
	on the vmeUniverse driver. It is now possible to use the ppc/shared/irq
	code on non-VME BSPs without triggering linkage of the vmeUniverse
	driver.

2003-03-25  Till Straumann <[e-mail]>

	on the vmeUniverse driver. It is now possible to use the ppc/shared/irq
	code on non-VME BSPs without triggering linkage of the vmeUniverse
	driver.

	code on non-VME BSPs without triggering linkage of the vmeUniverse
	driver.

2003-03-18  Till Straumann <[e-mail]>

	PR 356/bsps
	This patch makes RTEMS/powerpc/shared EABI compliant.
	* irq/irq_init.c, start/Makefile.am, start/start.S, startup/bspstart.c,
	startup/pgtbl_setup.c, vectors/vectors.h, vectors/vectors_init.c:
	zero_bss() should clear not only bss but sbss and sbss2
	also (this is probably a bugfix, as sbss/sbss2 are
	probably used even if -msdata=eabi is not specified).
	* start/rtems_crti.S: New file which must
	be linked immediately after ecrti.o. rtems_crti.o contains
	a code snippet who lets __init() return immediately. Also,
	a new entry point '_init' to the C++ Ctors is generated
	for use by the RTEMS Thread_Handler.

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

	PR 349/bsps
	* console/polled_io.c, console/reboot.c, irq/irq.c, irq/irq_asm.S,
	irq/irq_init.c, openpic/Makefile.am, startup/linkcmds,
	vectors/vectors.S, vectors/vectors_init.c:
	  - install the 'openpic.h' and 'pci.h' headers 
	  - avoid a name clash by renaming 'vsprintf' & friends
	    to 'k_vsprintf' etc.
	  - let 'rtemsReboot' print a stack trace (in case an 'assert' failed)
