8726M_ref # nand
nand - NAND sub-system

Usage:
nand info - show available NAND devices
nand device [dev] - show or set current device
nand read - addr off|partition size
nand write - addr off|partition size
    read/write 'size' bytes starting at offset 'off'
    to/from memory address 'addr', skipping bad blocks.
nand erase [clean|whole] [off size] - erase 'size' bytes from
    offset 'off' (entire device if not specified)
nand bad - show bad blocks
nand scrub_all- really clean NAND erasing bad blocks (UNSAFE)
nand dump[.oob] off - dump page
nand scrub_detect - detect bad blk again
clean NAND erasing bad blocks except factory bad blocks
       -just do it (SAFE)!!
nand scrub - clean NAND erasing bad blocks except factory bad blocks
       -just do it (SAFE)!!
nand markbad off [...] - mark bad block(s) at offset (UNSAFE)
nand biterr off - make a bit error at offset (UNSAFE)
nand  rom_protect  on/off
nand  wr_rd_cmp  src dst  off|partition size
nand  rom_write  addr off|partition size
