[U-Boot] [PATCH 1/2] rockchip: add basic partitions support for rk3288
For compatibility with distro boot, fastboot, and mount the mmc deivce to PC via usb mass storage feature, GPT partitions are essential.
You should write the partitions to mmc device prior to use above feature.
=> gpt write mmc 1 $partitions GPT successfully written to block device! success!

Enable ums feature for rk3288 boards, so that we can mount the mmc device to PC.
