[U-Boot] [PATCH] sun7i: Add support for Olimex A20-OLinuXino-LIME2

[Iain Paton <ipaton0@gmail.com>]

This adds support for the Olimex A20-OLinuXino-Lime2
https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2

Differences to previous Lime boards are 1GB RAM and gigabit ethernet

patch is substantially the same as the one previously posted to linux-sunxi
by HeHoPMaJIeH <gamishev@gmail.com> just updated for mainline.
The settings have been tested on real hardware, however I'm limited to the
two boards that I have. As yet there are no downloads available from Olimex 
for this board, so it's unknown if they will go for a more conservative
setting.
