Very nice, I didn't know about it. Unfortunately, this seems to suffer from the same problem as the generic "randconfig" -- it ignores all "choice" statements and just uses the default:
Try for instance
KCONFIG_ALLCONFIG=arch/arm/configs/omap2plus_defconfig make \ O=obj-allmod/ allnoconfig ARCH=arm
This is supposed to set CONFIG_ARCH_OMAP, but it instead chooses CONFIG_ARCH_VERSATILE, which means it's still useless for me.
