To make the PSCI backend more maintainable and easier to port to newer
SoCs, rewrite the current PSCI implementation in C.
Some inline assembly bits are required to access coprocessor registers.
PSCI stack setup is the only part left completely in assembly. In theory
this part could be split out of psci_arch_init into a separate common
function, and psci_arch_init could be completely in C.

I tried merging this in my tree to add it to u-boot-sunxi/next, but
unfortunately it triggers a bug in gcc-6.1, I've filed a bug with
gcc to get this fixed:
https://bugzilla.redhat.com/show_bug.cgi?id=1344717
Interesting. Seems like the compiler should be emitting LDMFD instead
of POP, or a POP followed by a SUBS/MOVS.
Also cp15_read_scr / cp15_write_scr are missing __secure notations.
Do you want me to send a new version for this?
No, I already have a local branch with this fixed.
As for getting this merged and Tom's "go for it"
comment earlier, I consider this a blocker for merging, sorry.
I hope that the gcc folks can resolve this soon and that I can
get the Fedora devs to deploy a fix soon-ish. I'm not sure what
other distros are doing wrt jumping to gcc-6.1, but having code
in u-boot master which does not build with the latest gcc seems
like a bad idea.

Hans
