* Makefile.am, shared/vmeUniverse/README.universe,
shared/vmeUniverse/vmeUniverse.c, shared/vmeUniverse/vmeUniverse.h:
Several VME related upgrades and fixes, hopefully addressing PR#835:
vmeUniverse driver now supports shared interrupts. vmeUniverse now
supports up to four wires between universe and PIC. A new irq mgr
installation routine has been added allowing to use the new features.
(old version is still present for bwd compatibility). Calls have been
added to change interrupt routing (e.g., if wires have different
priorities at the PIC this feature can be used to configure
priorites). Routine for testing VME interrupts has been added (useful
during BSP development). A new header defining standard VME address
modes has been added so that the VME API doesn't have to #include a
particular bridge driver header. For all driver entry points, a 'XX'
variant has been added which allows to pass the chip's base address
[in case a second universe is sitting on a VME card :-)]. Driver now
uses interrupt line as read from PCI config. space (without offset)
BSP needs to use PCI fixup if necessary. Added a driver for the
tundra tsi148 VME bridge.
* shared/vme/README, shared/vme/vme_universe.c: New files.
* Makefile.am, motorola_powerpc/Makefile.am, mvme5500/vme/vmeconfig.c,
shared/vme/VME.h, shared/vme/VMEConfig.h, shared/vme/vmeconfig.c:
Several VME related upgrades and fixes, hopefully addressing PR#835:
Separated API, API-implementation by a specific VME bridge driver and
BSP-specific configuration of the driver into different files,
describing their purpose in a README. All of these changes use the
upgraded vmeUniverse.c driver.
* include/bsp.h, vme/vmeconfig.c: Reverted redefinition of _IO_BASE;
this normally points to ISA space but is misused by this BSP
(inb/outb & friends are all over the place).
* shared/motorola/motorola.c, shared/pci/detect_raven_bridge.c,
shared/pci/pci.c, shared/pci/pci.h, shared/pci/pcifinddevice.c:
Several PCI enhancements and fixes: all BSP flavors now use the
generic clear_hostbridge_errors() routine (this means that only
polling memory probing is possible [see detect_raven_bridge.c for
details]). Interrupt fixup routine now supports multi-function
devices. Interrupt fixup routine now honours a flag/option so that
wrong firmware values can be overridden. Fixed irq routing table for
mvme2100 [PMC]. Added irq routing table for mvme2300. Added a
BSP_pciScan() routine that executes a user callback on each non-empty
slot/fun. Added BSP_pciConfigDump() to display basic config headers.
* shared/console/reboot.c, shared/start/start.S: Fixed PR#845;
!!enable MMU!! on mvme2100 - this is very important.
Otherwise, all accesses are write-back cached [incl. memory-mapped devices].
(Prerequisite were the changes to shared/startup/bspstart.c just
below.) Implemented rtemsReboot() for mvme2100.
* shared/irq/openpic_i8259_irq.c: New file.

specifica from generic irq handling into openpic_i8259_irq.c; added
some compilation conditionals to help BSPs without ISA to omit ISA
interrupts and calling i8259 code.
* Makefile.am, include/bsp.h: Added new shared pretaskinghook.c and
zerobss.c files to list to be made. Added some explanations about
CPU <-> PCI <-> VME address mapping issues.
* shared/startup/pretaskinghook.c, shared/startup/zerobss.c: New files.
* Makefile.am, shared/startup/bspstart.c: Split
pretaskinghook and zerobss into separate, reusable files; Fixed
#PR837 (set exception in ram flag before initializing exceptions);
Setup DBATs early, they are needed to access peripherals (Allows
mvme2100 to use MMU); moved VME initialization into pretasking hook
so that shared interrupts can be used for VME [shared IRQ facility
needs functional workspace].
* mvme5500/irq/irq.h, psim/irq/irq.h, shared/console/uart.c,
shared/irq/irq.h: Renamed BSP_ISA_UART_COMx_IRQ -> BSP_UART_COMx_IRQ
(uart driver is ISA independent).
Removed ugly #ifdef mvme2100. Added test for
BSP_UART_USE_SHARED_IRQS symbol which a BSP can define to request
that the serial interrupt be shared.
* shared/vectors/vectors.S: when returning
from an exception, reload stack pointer with value from exception
frame instead of adding a fixed value. -- maybe the exception handler
modified the frame with good reason (e.g., gdb pushed a dummy frame).

* shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
256 meg to allow operation on boards with larger RAM sizes.
* shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
vector function (mpc60x_vector_is_valid) instead of MPC750 specific
function to allow operation on boards with CPUs other than the
MPC750.

shared/vectors/vectors.h, shared/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.

* shared/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.
2001-04-08 Joel Sherrill <joel@OARcorp.com>
* shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame
2001-03-30 Eric Valette <valette@crf.canon.fr>
* shared/Makefile.am, shared/console/consoleIo.h,
shared/include/bsp.h: These modifications are part of the conversion
of the mpc8xx CPU to the "new exception processing model."
* configure.in, motorola_powerpc/Makefile.am,
motorola_powerpc/configure.in: These modifications are in support of
switching the mpc8xx to the use the "new exception processing
model."
2000-11-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2000-11-02 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
$(RTEMS_TOPdir)/aclocal.
2000-11-01 Joel Sherrill <joel@OARcorp.com>
* shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
and libcsupport.h moved from libc to lib/include/rtems and now must
be referenced as <rtems/XXX.h>. Header file order was cleaned up
while doing this.
2000-10-27 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
GNU canonicalization.
2000-09-29 Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
* shared/startup/linkcmds: Added lines so DWARF debug information
would be available. Otherwise gdb complains that the offsets for
the debug info are incorrect and doesn't load the files.
2000-09-05 Joel Sherrill <joel@OARcorp.com>
* shared/start/start.S: Include proper files to compile.

shared/startup/bspstart.c: moved linkcmds to shared area for other
BSPs to use
* startup/ldsegs.S: put IDT and GDT into data segment. The CPU modifies
the 'accessed' bit and GDB's (rtems-gdb-stub) text segment checksum
comparison failed...

added a simple API/library
for i2c devices and drivers for i2c 2-byte eeproms and a ds1621
temperature sensor; API is documented in libi2c.h
* mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: enhancements to mpc6xx page
table support - PTEs can now be modified even if the page table is
already active; bugfix: address range crossing 256MB boundary was not
handled correctly
* mvme5500/start/start.S, shared/start/start.S,
shared/startup/bspstart.c: moved assembly code to C; setdbat now
supports high bats on 7450 CPUs; added argument checking to setdbat;
added getdbat; moved early initialization code (clear_bats) from BSP
to libcpu (CPU_clear_bats_early)
* mpc6xx/mmu/bat.c, mpc6xx/mmu/bat.h, mpc6xx/mmu/mmuAsm.S: moved
