- 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 405EZ ports also show upon bootup from which boot device
they are configured to boot:
U-Boot 1.2.0-gd3832e8f-dirty (Apr 18 2007 - 07:47:05)
CPU: AMCC PowerPC 405EZ Rev. A at 199.999 MHz (PLB=133, OPB=66, EBC=66 MHz)
Bootstrap Option E - Boot ROM Location EBC (32 bits)
16 kB I-Cache 16 kB D-Cache
Board: Acadia - AMCC PPC405EZ Evaluation Board

This patch adds some 4xx GPIO functions. It also moves some of the
common code and defines into a common 4xx GPIO header file.

As provided by the AMCC applications team, this patch optimizes the
DDR2 setup for 166MHz bus speed. The values provided are also save
to use on a "normal" 133MHz PLB bus system. Only the refresh counter
setup has to be adjusted as done in this patch.
For this the NAND booting version had to include the "speed.c" file
from the cpu/ppc4xx directory. With this addition the NAND SPL image
will just fit into the 4kbytes of program space. gcc version 4.x as
provided with ELDK 4.x is needed to generate this optimized code.

This patch updates the recently added Katmai board support. The biggest
change is the support of ECC DIMM modules in the 440SP(e) SPD DDR2
driver.
Please note, that still some problems are left with some memory
configurations. See the driver for more details.

- Add support for PPC440EPx & PPC440GRx
- Add support for PPC440EP(x)/GR(x) NAND controller
in cpu/ppc4xx directory
- Add NAND boot functionality for Sequoia board,
please see doc/README.nand-boot-ppc440 for details
- This Sequoia NAND image doesn't support environment
in NAND for now. This will be added in a short while.
Patch by Stefan Roese, 07 Sep 2006
- Added onboard PPC440 DDR autodetection in cpu/ppc/sdram.c
- CFG_FLASH_QUIET_TEST added to use the common CFI driver
for bank autodetection
