The mem_is_flash() in arch/arm/mach-uniphier/micro-support_card.c writes/reads the tail of each NOR flash bank to check if the device really resides there.
If CS1_SPLIT were enabled, the support card would always require two NOR flash devices to be inserted for the correct NOR detection. This is not probably what we want.
