It looks like you are right. We fixed the bug in our UEFI and now this
patchset works.

So all 21 patches:

Tested-by: Timur Tabi <>

However, I did notice one thing. Booting the kernel displays this line:

[ 69.424001] Failed to find cpu0 device node

That's because CONFIG_OF is still defined (part of "config ARM64"), and
therefore cache_setup_of_node() attempts to get the cache information
from the device tree.

Should CONFIG_OF still be defined?
