From c231c4367ace6574e27ff0d1844d163fc471287b Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 16 Feb 2016 17:08:41 +0900 Subject: 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.
