a patch for storing grub state in NVRAM

[Eliezer]

I have made a patch to grub that adds the following functions.
NVRAM read write
nvramset ADDR VAL
nvramtest ADDR VAL
sets/tests value in address ADDR

I have modified the behavior of the fallback command so it is valid inside a
menu item
I have modified the behavior of grub so that when it is hidden menu mode it
dos not wait for a key press before attempting to load the fallback OS

I have added commands to set /stop three kinds of hardware watchdog.

I use all of these to have several OS versions on a machine and have grub
select a backup OS when the primary fails.

this patch is based on grub 0.90
the files go in the stage2 directory
except for nvramset.c which is a standalone linux program to set the nvram
without using the /dev/nvram device.

I am not on the mailing list so please reply by Email.
