3d61018643 The patch introduces the alternative configuration of the log buffer for the lwmon5 board: the storage for the log-buffer itself is OCM(on-chip memory), the log-buffer header is moved to six GPT registers (PPC440EPX_GPT0_COMP1, ..., PPC440EPX_GPT0_COMP5).
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).

8f15d4addd The patch adds new POST tests for the Lwmon5 board. These are:
* External Watchdog test;
* dsPIC tests;
* FPGA test;
* GDC test;
* Sysmon tests.

d8ab58b212 Replace "run load; run update" with conditionalized "run load update".
The latter version stops when "run load" fails for whatever reasons
rendering the combination *a lot* more secure.

2e721094a7 lwmon5: enable hardware watchdog
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.

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.

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.
