Both appear to be just variations of the plat_nand.c driver. > You would have hoped TS would use the NAND silicon already on the Marvell chip, but no they decided to use up FPGA LUT's to re-invent the wheel; although I do think their just pulled over the FPGA bitstream they were using in the TS-7200 series.
