[PATCH v2 00/13] Add support for Allwinner (sunxi) A64 SoC

[Jules Maselbas]

Hi all,

Here is the fresh update of patches for running barebox on sunxi soc,
rebased on 2023.05.0.

Main changes since rfc is the addition of an entry in the documentation,
the correction of some typo in both comments and code.

This series still has some rough edges and few `#if 0` still around. I need
a bit more time to decide if such things are really needed... or not.

I would like to get the eMMC working before this gets merged but I don't
know what happened on my board, so I am looking for more testers !

Cheers,
