Well, 16 MByte are doable and also happen on real hardware, but with
bigger chips you're out of luck. Both for SPI addressing reasons (24 bit
addresses by default) and for legacy reasons. I heard rumors that newer
x86 can handle larger flash chips, but AFAIK only with the help of PIO,
not directly mapped. Similar rule for Qemu.

That said, changing FLASH_MAP_BASE_MIN to

#define FLASH_MAP_BASE_MIN ((hwaddr)(0x100000000ULL - 16*1024*1024))

should work.
