Your patch seems not working. But the problem is teh follwing; maybe a fake of
mine;
cfi->cfiq->DevSize: 0x00000017
cfi->interleave: 1
number of CFI chips: 1
cfi->cfiq->NumEraseRegions: 2
cfi->numchips: 1
mtd->numeraseregions: 2
cfi->interleave: 1
Sum of regions (1000000) != total size of set of interleaved chips (800000)
Now I'm trying the jedec interface
I'll let you know.
