[U-Boot] [PATCH v2 1/4] sunxi: Add support for NanoPi M1

Mylène Josserand
2017-05-10T06:26:07Z

NanoPi M1 is a board based on Allwinner H3 CPU.

This commit adds the support for this platform with:
- an include device tree which enables UART, LEDs, GPIO key switch,
1 USB host ports and the SD-card as a dtsi file.
- a device tree specific to this board that enables the
2 additional USB ports
- a defconfig file for minimal support
- a section in MAINTAINERS (add myself)

Synchronized with the kernel device tree, from commits:
sun8i-nanopi.dtsi: 85d2913614d9ab899d23b7ab7d22d23cf45bd1de
sun8i-h3-nanopi-m1.dts: 10efbf5f16336b7540ad6a16aa1cb0b26bab033b
