This patch removes the duplicted implementations of the pci_pre_init()
function by introducing a weak default function for it. This weak default
has a different implementation for some PPC variants. It can be
overridden by a board specific version.

This patch removes the duplicted implementations of the pci_target_init()
function by introducing a weak default function for it. This weak default
has a different implementation for 440EP(x)/GR(x) PPC's. It can be
overridden by a board specific version (e.g. PMC440, korat).

This patch adds support to detect the amount of DDR2 SDRAM
on PMC440 modules. Detection is done by probing through
a list of available and supported hardware configurations
from 1GByte down to 256MB.

The static TLB entry is replaced by dynamically created entries.

The following individual I2C commands have been removed: imd, imm, inm,
imw, icrc32, iprobe, iloop, isdram.

The functionality of the individual commands is still available via
the 'i2c' command.

This change only has an impact on those boards which did not have
CONFIG_I2C_CMD_TREE defined.

This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and
changes the default from 8 to 1 for the legacy and the new MTD
NAND layer. This allows to remove all NAND_MAX_CHIPS definitions
in the board config files because none of the boards use multi
chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440
define

 #define NAND_MAX_CHIPS          CONFIG_SYS_MAX_NAND_DEVICE

but that's bogus and did not work anyhow.

U-Boot allows for configurable prompt strings using the
CONFIG_AUTOBOOT_PROMPT resp. CONFIG_MENUPROMPT definitions. So far,
the assumption was that any such user defined problts would contain
exactly one "%d" format specifier. But some boards did not.

To allow for flexible boot prompts without adding too complex code we
now allow to specify the whole list of printf() arguments in the user
definition. This is powerful, but requires a responsible user who
really understands what he is doing, as he needs to know for exanple
which variables are available in the respective context.

Now the cpu node setup ("timebase-frequency" and "clock-frequency") is

The 440EPx has a problem when the PCI_CACHE_LINE_SIZE register is
set to non-zero, because it doesn't support MRM (memory-read-
multiple) correctly. We now added the possibility to configure
this register in the board config file, so that the default value
of 8 can be overridden.

Here the details of this patch:

o drivers_pci_auto.c: introduce CFG_PCI_CACHE_LINE_SIZE to allow
  board-specific settings. As an example the sequoia board requires 0.
  Idea from Stefan Roese <sr@denx.de>.
o board/amcc/sequoia/init.S: add a TLB mapping at 0xE8000000 for the
  PCI IO-space. Obtained from Stefan Roese <sr@denx.de>.
o include/configs/sequoia.h: turn CONFIG_PCI_PNP back on and set
  CFG_PCI_CACHE_LINE_SIZE to 0.

- 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
