X-Git-Tag: accepted/tizen/unified/20201110.125028~335
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c8ccd776f3368fcef649a1dd057357493d0acc8;p=platform%2Fkernel%2Fu-boot.git

odroid xu3/xu4: add bootclone and ubootupgrade environment scripts

Script ubootupgrade:
This script allows updating U-Boot from file u-boot-mmc.bin
existing on boot partition, e.g. with SD card reader.

This is useful for XU4, when U-Boot upgrade is needed,
then it can be delivered with 'boot.img' as regular file
and upgraded by running:
run ubootupgrade

Script bootclone:
This script allows cloning bootloader firmware including:
- bl1, bl2, U-Boot ,and TZSW
from bootable SD card to clean eMMC card using XU3/XU4 board.

This is useful, when user have SD card reader only and wants prepare
a bootable eMMC card.

The script expects that SD is bootable and can be run as follows:
run bootclone
