ARM: HYP/non-sec/PSCI: emit DT nodes Generate the PSCI node in the device tree. Also add a reserve section for the "secure" code that lives in in normal RAM, so that the kernel knows it'd better not trip on it.

Shouldn't this line be architecture dependent?
Looking at the whole commit, how is this breaking things?
Shall this include armv7.h regardless which architecture is compiled? This didn't cause any problem until a recent commit a389531 changes armv7.h.
Yes, the include looks safe. This is one of those cryptic bisects, can you poke it a bit more and see what's causing the failure inside of the file?
You mean it is safe to include armv7.h even if I am building armv8 targets? When compiling armv8 targets, I have these warnings

The readl was added into armv7.h by commit a389531.
