This patch adds support for the matrix keyboard on the lwmon5 board.
Since the implementation in the dsPCI is kind of compatible with the
"old" lwmon board, most of the code is copied from the lwmon
board directory.

Changed storage type of cfg_simulate_spd_eeprom to const
Changed storage type of gpio_tab to stack storage
(Cannot access global data declarations in .bss until afer code relocation)
Improved SDRAM tests to catch problems where data is not uniquely addressable
(e.g. incorrectly programmed SDRAM row or columns)
Added CONFIG_PROG_SDRAM_TLB to support Bamboo SIMM/DIMM modules
Fixed AM29LV320DT (OpCode Flash) sector map

Change Lime SDRAM initialization to now support 100MHz and
133MHz (if enabled). Also the framebuffer is initialized to
display a blue rectangle with a white border.

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.

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.

- 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
