c25dd8fc25 ppc4xx: Add support for 2nd I2C EEPROM on lwmon5 board
This patch adds support for the 2nd EEPROM (AT24C128) on the lwmon5
board. Now the "eeprom" command can be used to read/write from/to this
device. Additionally a new command was added "eepromwp" to en-/disable
the write-protect of this 2nd EEPROM.

The 1st EEPROM is not affected by this write-protect command.

3ad6387873 ppc4xx: Add matrix kbd support to lwmon5 board (440EPx based)
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.

79f240f7ec lib_ppc: make board_add_ram_info weak
platforms wishing to display RAM diagnostics in addition to size,
can do so, on one line, in their own board_add_ram_info()
implementation.

this consequently eliminates CONFIG_ADD_RAM_INFO.

Thanks to Stefan for the hint.

466fff1a7b ppc4xx: Add pci_pre_init() for 405 boards

it's not needed anymore with the patch from Matthias Fuchs with
the "weak" pci_pre_init() implementation.
