Subject: ARM: SA1100: resize collie mtd to SZ_16M
The end-user models have all 2x8 = 16 Megabytes of NOR.
It seems that only some dev models/prototype had 32M.
With current code, giving size of 32M can confuse the detection.
JEDEC:
sa1100-0: Found 2 x16 devices at 0x0 in 32-bit bank
sa1100-0: Found different chip or no chip at all (mfr 0x4, id 0x3001) at 0x1000000
SA1100 flash: CFI device at 0x00000000, 16MiB, 32-bit
CFI:
sa1100-0: Found 2 x16 devices at 0x0 in 32-bit bank. Manufacturer ID 0x0000b0 Chip ID 0x0000b0
sa1100-0: Found 2 x16 devices at 0x1000000 in 32-bit bank
Intel/Sharp Extended Query Table at 0x0039
...
sa1100-0: 2 set(s) of 2 interleaved chips --> 2 partitions of 16384 KiB
SA1100 flash: CFI device at 0x00000000, 32MiB, 32-bit
