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.

Introduce the new logical option CONFIG_HAS_POST which is set when the
platform has CONFIG_POST set. Use CONFIG_HAS_POST in the post/ Makefiles
to determine should the POST libs be compiled for the selected target
platform, or not.
To avoid breaking u-boot linking process, the empty post/libpost.a file is
created for platforms which do not have POSTs.

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).

This patch adds CFG_OHCI_USE_NPS to the common USB-OHCI driver. This
way a board just needs to define this new option to enable the "force
NoPowerSwitching mode" instead of adding new CPU/architecture defines
to the USB source itself.
This new option will be used first with the new AMCC 460EX Canyonlands
board port, which will be posted in a few days.
This patch also fixes a small compilation problem when DEBUG is enabled.

460EX doesn't support a fixed bootstrap option to boot from 512 byte page
NAND devices. The only bootstrap option for NAND booting is option F for
2k page devices. So to boot from a 512 bype page device, the I2C bootstrap
EEPROM needs to be programmed accordingly.
This patch adds basic NAND booting support for the AMCC Canyonlands aval
board and also adds support to the "bootstrap" command, to enable NAND
booting I2C setting.
Tested with 512 byte page NAND device (32MByte) on Canyonlands.

This patch is a rework of the 4xx interrupt handling done while
adding the 460EX/GT support. Interrupts are needed on 4xx for the
EMAC driver.

This patch changes the physical addess parameter from 32bit to 64bit.
This is needed for 36bit 4xx platforms to access areas located
beyond the 4GB border, like SoC peripherals (EBC etc.).

Change the automatic local version to have the form -nnnnn-gSHA1SUMID,
where 'nnnnn' is the number of commits since the last tag (i.e.,
1.3.2-rc3). This makes it much easier to recognize "newer" versions
and to see how much has been changed since the referenced tag.
Stolen from Linux kernel's scripts/setlocalversio, see commit d882421f.
