efa35cf12d ppc4xx: Clean up 440 exceptions handling
- 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

193b4a3bb3 [PATCH] ppc4xx: Fix CONFIG_SYS_CLK_FREQ definition in Sequoia config file
A '3' got cut off in the formatting of the last patch to automatically
change the clock speed of the system clock on sequoia board.

e3b8c78bc2 ppc4xx: Detect if the sysclk on Sequoia is 33 or 33.333 MHz
The AMCC Secquoia board has been changed in a new revision from using a
33.000 MHz clock to a 33.333 MHz system clock. A bit in the CPLD
indicates the difference. This patch reads that bit and uses the correct
clock speed for the board. This code is backward compatable will all
prior boards. All prior boards will be read as 33.000.

4be23a12f2 [PATCH] Update Sequoia EBC configuration (NOR FLASH)
As spotted by Matthias Fuchs, the READY input should not be
enabled for the NOR FLASH on the Sequoia board.

23744d6b5b [PATCH] Remove PCI-PNP configuration from Sequoia/Rainier config file
When PCI PNP is enabled the pci pnp configuration routine is called
which sets the PCI_CACHE_SIZE_LINE to 8. This seems to generate some
problems with some PCI cards. For now disable the PCI PNP configuration.

e802594b6f [PATCH] Update Sequoia (440EPx) config file
The config file now handles the 2nd target, the Rainier (440GRx)
evaluation board better. Additionally the PPC input clock was
adjusted to match the correct value of 33.0 MHz.

0238898382 [PATCH] Add DDR2 optimization code for Sequoia (440EPx) board
This code will optimize the DDR2 controller setup on a board specific
basis.

Note: This code doesn't work right now on the NAND booting image for the
Sequoia board, since it doesn't fit into the 4kBytes for the SPL image.

d1a7254529 [PATCH] Select NAND embedded environment from board configuration
The current NAND Bootloader setup forces the environment
variables to be in line with the bootloader. This change
enables the configuration to be made in the board include
file instead so that it can be individually enabled.
