This implements the following:
partuuid mmc 0:1 -> prints the partition's UUID. partuuic mmc 0:1 uuid -> sets environment variable "uuid" to the partition's UUID.
This can be useful when writing a bootcmd which searches all known devices for something bootable, and then wants the kernel to use the same partition as the root device, e.g.:
partuuid ${devtype} ${devnum}:${rootpart} uuid setenv bootargs root=PARTUUID=${uuid} ...
I guess one thing I might mention here:
I can imagine other partition-oriented commands existing, e.g. a command to find the bootable partition on a particular storage device. I'm not sure if we should create a single "part" command with various sub-options for this, e.g.:
part uuid mmc 0:1 part get-bootable mmc 0
I'm now working at restoring the GPT (GUID Partition Table) at MMC in u-boot.
I plan to implement a separate command - gptrestore However, I think that one single command would be more suitable for this purpose.
or create separate commands:
partuuid mmc 0:1 part-get-bootable mmc 0
