The last patch in this series causes onenand not to show
up on my n900. I believe the problem has been there earlier
too, but I just did not notice it.
Without the last patch in this series I get:
[ 1.650207] OneNAND driver initializing
[ 1.655487] omap2-onenand omap2-onenand: initializing on CS0, phys base 0x04000000, virtual base d0880000, freq 83 MHz
[ 1.666931] OneNAND Manufacturer: Numonyx (0x20)
[ 1.671905] Muxed OneNAND 256MB 1.8V 16-bit (0x40)
[ 1.676971] OneNAND version = 0x0031
[ 1.918762] Creating 6 MTD partitions on "omap2-onenand":
And with this patch applied I get:
[ 1.634643] OneNAND driver initializing
[ 1.640075] omap2-onenand omap2-onenand: initializing on CS0, phys base 0x04000000, virtual base d0880000, freq 54 MHz
[ 1.651519] OneNAND Manufacturer: Unknown (0xa0)
