From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>
This adds support for the BananaPi R2 Pro board.
It is basicly a copy of rk3568 evb board but with slightly modified DTS.
Added GPIO-Leds to dts and modified the hw-detection a bit.
Tested features so far are:
- 1st stage booting
- Network
- SD card (Emmc not tested but basicly same as on EVB)
- power LED (green)
Signed-off-by: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>
