This patch should enable read/write/erase support for these chips, but does *not* implement unlock functionality for them yet, because they have more complex protection features than simply BPx block-protect bits.

IDs: 0x37 0x3010 is A25L512 (uniform 4k sectors) 0x37 0x3011 is A25L010 (uniform 4k sectors) 0x37 0x3012 is A25L020 (uniform 4k sectors) 0x37 0x3013 is A25L040 (uniform 4k sectors) 0x37 0x3014 is A25L080 (uniform 4k sectors) 0x37 0x3015 is A25L016 (uniform 4k sectors) 0x37 0x3016 is A25L032 (uniform 4k sectors) 0x37 0x4016 is A25LQ032 (uniform 4k sectors, has quad-rate read)
Please note that the IDs of the newer chips all use AMIC_ID_NOPREFIX instead of AMIC_ID, and that means they use probe_spi_rdid instead of probe_spi_rdid4.
