The new function remove_tlb() can be used to remove the TLB's used to
map a specific memory region. This is especially useful for the DDR(2)
setup routines which configure the SDRAM area temporarily as a cached
area (for speedup on auto-calibration and ECC generation) and later
need this area uncached for normal usage.

- Add optional ECC generation routine to preserve existing
RAM values. This is needed for the Linux log-buffer support
- Add optional DDR2 setup with CL=4
- GPIO50 not used anymore
- Lime register setup added

This patch removes the CFG_PCI_PRE_INIT option completely, since
it's not needed anymore with the patch from Matthias Fuchs with
the "weak" pci_pre_init() implementation.

A new environment variable, "logversion", selects the log buffer
behaviour. If it is not set or set to a value other than 2, then the
old, Linux 2.4.4, behaviour is selected.

- Show on the Status LEDs, some States of the board.
- Get the MAC addresses from the EEProm
- use PREBOOT
- use the CF on the board.
- check the U-Boot image in the Flash with a SHA1
checksum.
- use dynamic TLB entries generation for the SDRAM

- adapt to the more generic EXCEPTION_PROLOG and CRIT_EXCEPTION macros
- minor 4xx cleanup

The latest changes showed a problem with the location of the NAND-SPL
image in the OCM and the init-data area (incl. cache). This patch
fixes this problem.

- 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

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 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.
