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.

This patch adds a board command to configure the I2C bootstrap EEPROM
values. Right now 533 and 667MHz are supported for booting either via NOR
or NAND FLASH. Here the usage:

=> bootstrap 533 nor        ;to configure the board for 533MHz NOR booting
=> bootstrap 667 nand       ;to configure the board for 667MHz NNAND booting

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

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 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 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.
The main reason for this is the more compact code. This makes
it possible to include the ECC code into the NAND bootloader
image (NAND_SPL) for PPC4xx.
