Support for DiskOnChip G4 found in drivers/mtd/nand/raw/Kconfig

The configuration item CONFIG_MTD_NAND_DOCG4:

Help text

Support for diskonchip G4 nand flash, found in various smartphones and PDAs, among them the Palm Treo680, HTC Prophet and Wizard, Toshiba Portege G900, Asus P526, and O2 XDA Zinc.

With this driver you will be able to use UBI and create a ubifs on the device, so you may wish to consider enabling UBI and UBIFS as well.

These devices ship with the Mys/Sandisk SAFTL formatting, for which there is currently no mtd parser, so you may want to use command line partitioning to segregate write-protected blocks. On the Treo680, the first five erase blocks (256KiB each) are write-protected, followed by the block containing the saftl partition table. This is probably typical.
