[RFC PATCH 00/11] Add support for Allwinner (sunxi) A64 SoC

[Jules Maselbas]

Hi all,

I have been trying to port barebox on sun50i/A64 SoC targeting the pineA64
single board computer and the pinephone from Pine64.

Currently only the SD/MMC driver have been ported. It does work with SD card
and have worked on eMMC in the past but I might have fried my board...

This patch series has some rough edges, I am looking forward you're insights.

Cheers,

Jules Maselbas (11):
