Title:
  ARM: RES0/RES1 SCTLR fields not read-only

Status in QEMU:
  Confirmed

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.
