Module Name: src
Committed By: thorpej
Date: Wed Jun 5 03:38:09 UTC 2019
Modified Files:
src/sys/arch/evbarm/conf: GENERIC
Added Files:
src/sys/arch/arm/dts: sun8i-h2-plus-bananapi-p2-zero.dts
Log Message:
Add a device tree for the Banana Pi BPI-P2 Zero. This device is
based on the BPI-M2 Zero, with a couple of small changes:
- On-board Ethernet (with optional PoE support)
- On-board eMMC.
- Card-detect for the SD card slot is wired up a little differently.
Kindly tested by Dima Veselov.
