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 ...
