config MTD_PARSER_TRX tristate "Parser for TRX format partitions" depends on MTD && (BCM47XX || ARCH_BCM_5301X || COMPILE_TEST) help TRX is a firmware format used by Broadcom on their devices. It may contain up to 3/4 partitions (depending on the version). This driver will parse TRX header and report at least two partitions: kernel and rootfs. config MTD_SHARPSL_PARTS tristate "Sharp SL Series NAND flash partition parser" depends on MTD_NAND_SHARPSL || MTD_NAND_TMIO || COMPILE_TEST help This provides the read-only FTL logic necessary to read the partition table from the NAND flash of Sharp SL Series (Zaurus) and the MTD partition parser using this code. config MTD_REDBOOT_PARTS tristate "RedBoot partition table parsing" help RedBoot is a ROM monitor and bootloader which deals with multiple 'images' in flash devices by putting a table one of the erase blocks on the device, similar to a partition table, which gives the offsets, lengths and names of all the images stored in the flash. If you need code which can detect and parse this table, and register MTD 'partitions' corresponding to each image in the table, enable this option. You will still need the parsing functions to be called by the driver for your particular device. It won't happen automatically. The SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for example. if MTD_REDBOOT_PARTS config MTD_REDBOOT_DIRECTORY_BLOCK int "Location of RedBoot partition table" default "-1" help This option is the Linux counterpart to the CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time option. The option specifies which Flash sectors holds the RedBoot partition table. A zero or positive value gives an absolute erase block number. A negative value specifies a number of sectors before the end of the device. For example "2" means block number 2, "-1" means the last block and "-2" means the penultimate block. config MTD_REDBOOT_PARTS_UNALLOCATED bool "Include unallocated flash regions" help If you need to register each unallocated flash region as a MTD 'partition', enable this option. config MTD_REDBOOT_PARTS_READONLY bool "Force read-only for RedBoot system images" help If you need to force read-only for 'RedBoot', 'RedBoot Config' and 'FIS directory' images, enable this option. endif # MTD_REDBOOT_PARTS
