This patch adds support for this board, including ethernet, LCD and USB
support.
Thanks, I've merged this and it will show up in u-boot-sunxi/next soon.
Thanks.
I've made 2 small changes, see comments inline.

I've dropped this, I understand that you need it, but I do not believe that
ANY defconfig's as shipped upstream should set this.
Hmmm. I would prefer to have this added to the defconfig as well.
As it very likely leads to confusion when updating to a newer
U-Boot version which will not support the old kernel. Why not give
the users / maintainers the freedom to choose this for themselves?
Users are free to choose this, they can always enable this themselves
after running make foo_defconfig.
As for why not give the MAINTAINERS a choice on this, as said
I believe that we should not shipp defconfigs with this set by default
as part of mainline u-boot. The reasons for this are:
1) It is inconsistent with what we are doing for all other sunxi boards
where we are primarily targetting mainline
2) It communicates that CONFIG_OLD_SUNXI_KERNEL_COMPAT is an officially
supported end-user feature, where as in reality it is targeted at developers
who need to run an old sunxi kernel every now and then to see how that
kernel exactly programs certain registers, etc.
3) It means we ship with a severely crippled defconfig for mainline kernel
users, mainline users will loose both smp and hyp mode support on the A20
when this option is set.
I'm sorry but I'm not going to budge on this one, having
CONFIG_OLD_SUNXI_KERNEL_COMPAT=y in a defconfig is simply not acceptable
IMHO. It is not a board specific thing, and there are very good reasons
why it defaults to n in board/sunxi/Kconfig

I've dropped AXP209_POWER from these, in u-boot-sunxi/next this has been
turned into a Kconfig bool which is enabled by default on sun7i.
Understood.
Thanks,
Stefan
