What surprised me though is that it's enabled by default:
$ grep REVB arch/arm/configs/realview*
arch/arm/configs/realview_defconfig:CONFIG_REALVIEW_EB_ARM11MP_REVB=y
arch/arm/configs/realview-smp_defconfig:CONFIG_REALVIEW_EB_ARM11MP_REVB=y
With that option set, the defconfig kernel should not be able
to boot on RevC machines. Do you have a RevC machine that works
with the defconfig?
