Hi, I'm looking at adding support for the Micron MT29F1G08ABAFAWP-ITE:F chip to one of our boards which uses the Marvell NFCv2 controller.
This particular chip is a bit odd in that the datasheet states support for ONFI 1.0 but the revision number field is 00 00. It also is marked ABAFA but reports internally as ABAGA. Finally it has internal 8-bit ECC which cannot be disabled. I think that last point may cause some hassle since the internal ECC implementation is probably not compatible with the Marvell NFCv2 implementation. This series is very much RFC because even with these changes so far I don't have a working system. Here's a dump of the parameter page if anyone is interested 00000000: 4f 4e 46 49 00 00 18 00 3f 00 00 00 00 00 00 00 ONFI....?....... 00000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000020: 4d 49 43 52 4f 4e 20 20 20 20 20 20 4d 54 32 39 MICRON MT29 00000030: 46 31 47 30 38 41 42 41 47 41 57 50 20 20 20 20 F1G08ABAGAWP 00000040: 2c 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ,............... 00000050: 00 08 00 00 80 00 00 02 00 00 20 00 40 00 00 00 .......... .@... 00000060: 00 04 00 00 01 22 01 14 00 01 05 08 00 00 04 00 .....".......... 00000070: 08 01 0e 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000080: 08 3f 00 3f 00 58 02 10 27 46 00 64 00 00 00 00 .?.?.X..'F.d.... 00000090: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 000000a0: 00 00 00 00 01 00 00 00 00 02 04 80 01 81 04 03 ................ 000000b0: 02 01 1e 90 00 00 00 00 00 00 00 00 00 00 00 00 ................ 000000c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 000000d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 000000e0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 000000f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 85 a6 ................
