ENGR00174536-1 booti: add booti command support.
Support booti command which can boot from a boot.img
boot.img is a zImage + ramdisk.img + bootargs + boot addr
which include these info can be used to avoid mis match between
kernel and ramdisk, also can avoid commit to chagne default
bootargs.
For example:
> booti mmc1
command will read the boot.img from 1M offset,
and then parser the bootargs and ramdisk
then do the boot from that zImage.
> booti mmc1 recovery
will going to read the recovery's partition no
and offset and boot from recovery image.
this recovery image also a zImage + ramdisk
bootargs:
if uboot have define a env var 'bootargs', booti command
will use this bootargs as kernel cmdline
if you want use boot.img 's bootargs, just type:
> setenv bootargs
in uboot to clear the bootargs in uboot env.
our default uboot env will be NULL in config file.
also, android use boot.img to support OTA.
