Subject: [PATCH] NAND: Make nboot skip bad blocks
nboot command currently does not skip bad blocks and gives read error when
loading image stored over bad block. With patch applied, nboot works as
expected:
Device 0 bad blocks:
00780000
014a0000
02000000
02cc0000
04aa0000
Loading from NAND 128MiB 3,3V 8-bit, offset 0x2c00000
Image Name: Linux-2.6.22-omap1
Created: 2008-11-20 23:44:32 UTC
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 1052520 Bytes = 1 MB
Load Address: 10008000
Entry Point: 10008000
Skipping bad block 0x02cc0000
Automatic boot of image at addr 0x10400000 ...
