The RCW source should probably be 0x107, not 0x104.  Bit 0x002 requests
first/last bad block markers rather than first/second, and bit 0x001
enables ECC.  Also, this documentation is LS2085A-specific (most of it
will probably apply to all chips with this chassis), not RDB or QDS
specific, with the exception of the RCW source ID which depends on the
specific NAND chip.  It would be better to put it in one place rather
than duplicate it, with a table of RCW source IDs for each board.

Also, you have RDB as having SRC=0x104, but that (as well as 0x107) is
for a 2K-page NAND chip.  RDB has a 4K-page NAND, so I think you want
RCW source to be 0x111.
