From: weichangzheng nicholas_zheng@outlook.com
This adds platform code and the device tree for the Phytium Pomelo Board. The initial support comprises the UART and the PCIE.
Signed-off-by: weichangzheng nicholas_zheng@outlook.com Changes since v1:
- updated to DT
You've sent a number of these patches and they've all been V1 and don't have an updated change log as to what has changed between the versions. Please provide a list of what has changed with each new version you post, if nothing has changed please don't keep resending the patch, it's just confusing and annoying and is extremely unlikely to encourage someone to review it earlier.
