d32a874b9b lwmon5 watchdog: limit trigger rate
Limit the rate of h/w watch-dog triggering on the LWMON5 board by
the CONFIG_WD_MAX_RATE value.

Note that an earlier version of this patch which used microseconds
instead of ticks dis not work. The problem was that we used
usec2ticks() to convert microseconds into ticks. usec2ticks() uses
get_tbclk(), which in turn calls get_sys_info(). It turns out that
this function does a lot of prolonged operations (like divisions)
which take too much time so we do not trigger the watchdog in time,
and it resets the system.

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.

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.
