pflash_cfi02_register() takes a size in bytes, a block size in bytes
and a number of blocks. r2d_init() passes FLASH_SIZE, 16 * KiB,
FLASH_SIZE >> 16. Does not compute: size doesn't match block size *
number of blocks. The latter happens to win: FLASH_SIZE / 4,
i.e. 8MiB.
The best information we have on the physical hardware lists a Cypress
S29PL127J60TFI130 128MiBit NOR flash addressable in words of 16 bits,
in sectors of 4 and 32 Kibiwords. We don't model multiple sector
sizes.
Fix the flash size from 8 to 16MiB, and adjust the sector size from 16
to 64KiB. Fix the width from 4 to 2. While there, supply the real
device IDs 0x0001, 0x227e, 0x2220, 0x2200 instead of zeros.
