X-Git-Tag: submit/tizen/20201110.005738~191
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b9327b39fac96662765b18cbf16977e5c2f6f0c5;p=platform%2Fkernel%2Fu-boot.git

config: odroid-xu3: add dfu_alt_system information version 2

Add the dfu_alt_system information version 2.
It's used to flash a ramdisk.img at partition 7.
If there is no partition 7, it will load from mmcbootpart as mmcblk0p1.
