Thanks, I've added this to my personal git repo, sunxi-wip
branch. I'll move it over to u-boot-sunxi/next once it
is clear that the kernel patch to show the devicetree
serial-number string /proc/cpuinfo is going to be accepted.

Regards,

Hans

Thanks, I'm currently busy merging some more patches, once that
is done this patch should show up in u-boot-sunxi/next, and
it will be included in u-boot/master once the merge window
for v2015.07 opens.

Regards,

Hans
