To enable this, alternative, configuration the U-Boot board configuration
file for lwmon5 includes the definitions of alternative addresses for header
(CONFIG_ALT_LH_ADDR) and buffer (CONFIG_ALT_LB_ADDR).
The Linux shall be configured with the CONFIG_ALT_LB_LOCATION option set,
and has the BOARD_ALT_LH_ADDR and BOARD_ALT_LB_ADDR constants defined in the
lwmon5 board-specific header (arch/ppc/platforms/4xx/lwmon5.h).

The latter version stops when "run load" fails for whatever reasons
rendering the combination *a lot* more secure.

Some boards (e.g. lwmon5) may use rather small watchdog intervals, so
causing it to reboot the board if U-Boot does a long busy-wait with
udelay(). Thus, for these boards we have to restart WD more
frequently.
This patch splits the busy-wait udelay() into smaller, predefined,
intervals, so that the watchdog timer may be resetted with the
configurable (CONFIG_WD_PERIOD) interval.

This patch configures the LWMON5 port to use d-cache as init-ram and
the unused GPT0_COMP6 as POST WORD storage.

On Sequoia & LWMON5 the virtual address of the POST cache test is now
moved to a bigger address. This enables usage of more memory on those
boards.

The Linux PCF8563 RTC driver doesn't do autoprobing, so we need
to supply the RTC I2C address as bootline parameter. This patch
adds support for this rtc probing parameter to the bootargs:
"rtc-pcf8563.probe=0,0x51"

Since this RTC POST test is taking quite a while to complete
it's only initiated upon special keypress same as the complete

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.

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.

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.

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.

When PCI PNP is enabled the pci pnp configuration routine is called
