[U-Boot-Users] PATCH: itest - an integer compare function

[Robin Gilks <robin.gilks@tait.co.nz>]

Changelog:
Introduce a new command to be used in conditional expressions (such as 
hush 'if') to test the value of a memory location.
Supports -eq, -ne, -gt, -lt, -ge, -le
Allows scalars or memory contents (value prefixed by '*')
Makes use of command data width expression of .l, .wm .b for 4, 2 or 1 
byte wide comparisons
e.g.
if itest.l *40000 -eq 12345678; then bootm 41000; else bootm 80000; fi


Patch is against u-boot-1.0.0


Note: I'm still concerned that the CONFIG_COMMANDS mask has run out of 
bits - maybe time for a different mechanism as I'm sure the bit I've 
used has gone by now!!
