- Introduced dedicated switches for building 440 and 405 images required
for 440-specific machine instructions like 'rfmci' etc.
- Exception vectors moved to the proper location (_start moved away from
the critical exception handler space, which it occupied)
- CriticalInput now serviced (with default handler)
- MachineCheck properly serviced (added a dedicated handler and return
subroutine)
- Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
unhandled and those not relevant for 4xx were eliminated)
- Eliminated Linux leftovers, removed dead code

Now program_tlb() allows to program a TLB (or multiple) with
different virtual and physical addresses. With this change, now one
physical region (e.g. SDRAM) can be mapped 2 times, once with caches
diabled and once with caches enabled.

This is a cosmetic only changes submission.
It affects files relevant to bcm570x driver.
the commands used to generate this change was
cd drivers
Lindent -pcs -l80 bcm570x.c bcm570x_lm.h bcm570x_mm.h tigon3.c tigon3.h
The BMW target (the only one using this chip so far) builds cleanly, the
`before and after' generated object files for drivers/bcm570x.c and
drivers/tigon3.o are identical as reported by objdump -d

This patch adds NAND booting support for the AMCC Acadia eval board.
Please make sure to configure jumper J7 to position 2-3 when booting
from NOR, and to position 1-2 when booting for NAND.
I also added a board command to configure the I2C bootstrap EEPROM
values. Right now only 267MHz is support for booting either via NOR
or NAND FLASH. Here the usage:
=> bootstrap 267 nor ;to configure the board for 267MHz NOR booting
=> bootstrap 267 nand ;to configure the board for 267MHz NNAND booting

This patch added USB PCI-OHCI chips support, interrupt pipe support
and usb event poll support. For supporting the USB interrupt pipe, the
globe urb_priv is moved to purb in ed struct. Now, we can process
several urbs at one time. The interrupt pipe support codes are ported
from Linux kernel 2.4.

Using some (very) slow USB keys cause the USB host controller buffers
are not ready to be read by the CPU so we need an extra delay before
reading the USB storage data.

Current include/configs/MPC8349ITX.h does contain some support for building
image that will be started from memory (without putting in into flash).
It could be triggered by building with TEXT_BASE set to a low value.
However, this support is incomplete: using of low TEXT_BASE causes
defining configuration macros in inconsistent way, which later leads
to compilation errors. In particular. flash support is being disabled,
but then flash structures get referenced.
This patch fixes this, making it possible to build with low TEXT_BASE.

This patch undoes the patch by Jeff Mann with commit-id ada4697d. As
suggested by AMCC it is not recommended to dynamically change the EBC
speed after bootup. So we undo this change to be on the safe side.

This patch adds NAND booting support for the AMCC Bamboo eval board.
Since the NAND-SPL boot image is limited to 4kbytes, this version
only supports the onboard 64MBytes of DDR. The DIMM modules can't be
supported, since the setup code for I2C DIMM autodetection and
configuration is too big for this NAND bootloader.

This patch adds hardware ECC support to the NDFC driver. It also
changes the register access from using the "simple" in32/out32
functions to the in_be32/out_be32 functions, which make sure
that the access is correctly synced. This is the only recommended
access to SoC registers in the current Linux kernel.

This patch updates the nand_ecc code to the latest Linux version.
