rockchip: use UUID for root partitions
We use to use /dev/mmcbl0p7 as root partition, and pass it to kernel by cmdline, but the mmc number in kernel in not fixed, we need to change the bootargs to adapt it from time to time. We can use the UUID to fix it, the ID is from: https://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec/ ARM 32bit: 69dad710-2ce4-4e3c-b16c-21a1d49abed3 ARM 64bit: b921b045-1df0-41c3-af44-4c6f280d3fae Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Acked-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Reviewed-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
