Hi Paul!

I'm referring to your change [1]:

"powerpc/xmon: Fix SPR read/write commands and add command to dump SPRs"

which introduced assembly code in the new file arch/powerpc/xmon/spr_access.S.

Unfortunately, this code contains assembly instructions which are not available on
all ppc targets. In particular, this change breaks the build on PPC e500v2 targets,
see the corresponding Debian bug report [2].

Could you have a look and possibly add some guarding #ifdefs for the ppc targets
where "ld" is not a supported instruction?

Thanks,
Adrian
