[U-Boot] [PATCH 12/13] sunxi: add support for Allwinner H6 SoC

Icenowy Zheng icenowy at aosc.io
Mon Jun 25 10:37:22 UTC 2018


Allwinner H6 is a new SoC from Allwinner features USB3 and PCIe
interfaces.

This patch adds support for it.

As this is a new SoC supported by mainline U-Boot, the MMC env support
is dropped and only FAT env is available.
