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.

Add fastboot driver support for android. In this commit,

1) Reboot board
>fastboot reboot
2) Get information of board, e.g, product name
>fastboot getvar product
3) Download images in PC and flash to SD card
>fastboot flash bootloader u-boot-no-padding.bin
>fastboot flash kernel uImage
>fastboot flash uramdisk uramdisk.img
>fastboot flash system system.img
>fastboot flash recovery recovery.img
Certainly, SD card must have been formatted as Android user
guider doc already.
