Hi All, This patch adds support for Samsung Flex-OneNAND devices.
Flex-OneNAND combines SLC and MLC technologies into a single device. SLC area provides increased reliability and speed, suitable for storing code and data, such as bootloader, kernel and root file system. MLC area provides high density and is best used for storing user data. Users can configure the size of SLC and MLC regions through 'onenand setboundary' command.

Sorry for the late reply...
extern struct mtd_info onenand_mtd; extern struct onenand_chip onenand_chip; +loff_t flexonenand_get_addr(int block)
Space before function declarations.
- for (block = start; block <= end; block++) {
if (FLEXONENAND(this))instr.addr = flexonenand_get_addr(block);elseinstr.addr = block << onenand_chip.erase_shift;if (FLEXONENAND(this) && (mtd->numeraseregions > 1)) {for (i = 0; i < mtd->numeraseregions &&mtd->eraseregions[i].offset <= instr.addr;i++)
Patch is line-wrapped.
Can some of this be abstracted through the driver interface, rather than putting a bunch of stuff into what should be a relatively straightforward command-line wrapper?
Perhaps the two regions should be exposed as separate devices.
