mtd: rawnand: fsmc: Default to autodetect buswidth
If you don't specify buswidth 2 (16 bits) in the device
tree, FSMC doesn't even probe anymore:
fsmc-nand 10100000.flash: FSMC device partno 090,
manufacturer 80, revision 00, config 00
nand: device found, Manufacturer ID: 0x20, Chip ID: 0xb1
nand: ST Micro 10100000.flash
nand: bus width 8 instead of 16 bits
nand: No NAND device found
fsmc-nand 10100000.flash: probe with driver fsmc-nand failed
with error -22
With this patch to use autodetection unless buswidth is
specified, the device is properly detected again:
fsmc-nand 10100000.flash: FSMC device partno 090,
manufacturer 80, revision 00, config 00
nand: device found, Manufacturer ID: 0x20, Chip ID: 0xb1
nand: ST Micro NAND 128MiB 1,8V 16-bit
nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64
fsmc-nand 10100000.flash: Using 1-bit HW ECC scheme
Scanning device for bad blocks
I don't know where or how this happened, I think some change
in the nand core.
