Subject: mips: xilfpga: Add device tree files
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=d4e85377e79f52172c1df7469bf7d56ab0a85322;p=u-boot.git

mips: xilfpga: Add device tree files

Mostly the same as the Kernel upstream device tree file except for

- alias for the serial console node
- ethernet node as the ethernet stuff isn't upstream on kernel.org yet
- uart clock-frequency passed directly in the node
