The DiskOnChip _is_ NAND flash. It's just typically used with its own 'translation layer' which pretends to be a block device. If you're willing to put a small amount of effort into completing the bad-block-table support in the new DiskOnChip driver which uses the generic NAND code, you can use JFFS2 on it. -- dwmw2 ** Sent via the linuxppc-embedded mail list.
