ARM: uniphier: add emmcupdate command
The Boot ROM expects the boot image (SPL) in the Boot Partition 1. So, updating images involves the hardware partition switch. It might be a bit advanced for some users. To be user-friendly, this commit adds a useful command to update the images; just put SPL and U-Boot proper into the public directory of the TFTP server and execute "run emmcupdate" from the command line.
