Subject: Xilinx: ARM: Use existing go support for ep107 targets
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b1856b4403a932ced544fd38ff10326a46878ccb;p=thirdparty%2Fu-boot.git

Xilinx: ARM: Use existing go support for ep107 targets

Since bootm is slow in ep107 targets, enabled existing go
for automatic Linux booting in all bootmodes.

For proper linux boot, use correct linux defconfig with
fixed devicetree and devicetree with fixed ramdisk address.
