Hi Hans!
Thanks for all the great work you're doing. I really appreciate it.
I've been following your progress, first with the sunxi-test branch and now
with the sunxi-next branch.
Regrading the sunxi-next branch... as far as I can tell everything seems to be
working nice on my A20 Olinuxino micro.
(I've enabled USB in the dts file and it works nicely.)
However, I think there is one regression compared to the sunxi-test branch: SMP
for A20 doesn't work anymore.
I'm pretty sure its because the "ARM: sun6i: Add SMP support for the Allwinner
A31" only support SUN6I,
but wanted to double check with you to be sure that I didn't do anything stupid
on my side :).
You're likely missing CONFIG_ARM_PSCI=y in your .config for the kernel, this is
know to cause CPU 1
to not come up with sunxi-next. I've dropped explicit sunxi smp support for A20
in my sunxi-next
tree, as the plan for upstream is to implement the CPU bringup in u-boot and
use PSCI.
This is one of the reasons why you also need to use my u-boot sunxi-next
branch, which has the necessary
PSCI bits on the u-boot side.
Regards,
Hans
