[U-Boot] A23 u-boot with SPL / dram init available in my personal git repo

[Hans de Goede]

Hi,

This is still a bit rough around the edges, I'll clean it up as
time permits and then post it upstream.

In the mean time people interested can find $subject here:
https://github.com/jwrdegoede/u-boot-sunxi/commits/sunxi-wip

ChenYu, this also has a mmc fix which you may find interesting,
it may explain some of the problems with mmc you've been having
on both the A80 board, as well as the A31 dev board you've.

Regards,

Hans
