CVS commit: src/sys/arch/powerpc

["Jason R Thorpe" <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej
Date:           Sat Feb 13 01:48:33 UTC 2021

Modified Files:
        src/sys/arch/powerpc/oea: ofw_subr.S
        src/sys/arch/powerpc/powerpc: openfirm.c

Log Message:
- Don't change to the OFW stack in C code; instead, switch to the OFW
  stack in the openfirmware() wrapper itself.  Inspired by a similar
  change in OpenBSD designed to appease clang.
- The OF_*() entry firmware interfaces use several global resources;
  protect those global resources with a __cpu_simple_lock_t.
- Make ofbcopy() static -- it's no longer referenced outside openfirm.c
