This part of the series is not required for the eSDHC quirk,
but it restores the asm/fsl_guts.h header so it doesn't accidentally
get abused for this in the future. I found two drivers outside of
arch/powerpc that already accessed the registers directly, but the
functions look fairly contained, and can be easily hidden in an
#ifdef CONFIG_PPC

NACK

Besides adding ifdef pollution for no good reason, this register block is used
on some ARM chips as well.  Why is it a problem if "anyone starts using it on
ARM"?

BTW, of all the mailing lists you included on this CC, you seem to have left
off the PPC list (I've added it).
