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 <timur@codeaurora.org>
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?
