Well, I wouldn't object to a patch to fix it (it would have to correctly
handle the various different versions of the CPU architecture we
implement, etc), but I'm not planning on writing one today myself.

  ARM: SCTLR fields not being preserved

Status in QEMU:

Bug description:
  There are fields in SCTLR that are RAO/SBOP or WI or in the case of
  the RR field, accessible only in secure mode. Currently it seems that
  qemu just propagates any write to SCTLR to the register and this
  screwed up in a bootloader that I am debugging.
