24 tristate "Command line partition table parsing"
27 Allow generic configuration of the MTD partition tables via the kernel
28 command line. Multiple flash resources are supported for hardware where
29 different kinds of flash memory are available.
31 You will still need the parsing functions to be called by the driver
32 for your particular device. It won't happen automatically. The
33 SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
36 The format for the command line is as follows:
38 mtdparts=<mtddef>[;<mtddef]
39 <mtddef> := <mtd-id>:<partdef>[,<partdef>]
40 <partdef> := <size>[@offset][<name>][ro]
41 <mtd-id> := unique id used in mapping driver/device
42 <size> := standard linux memsize OR "-" to denote all
46 Due to the way Linux handles the command line, no spaces are
47 allowed in the partition definition, including mtd id's and partition
52 1 flash resource (mtd-id "sa1100"), with 1 single writable partition:
55 Same flash, but 2 named partitions, the first one being read-only:
56 mtdparts=sa1100:256k(ARMboot)ro,-(root)
61 tristate "OpenFirmware (device tree) partitioning parser"
65 This provides a open firmware device tree partition parser
66 which derives the partition map from the children of the
67 flash memory node, as described in
68 Documentation/devicetree/bindings/mtd/partition.txt.

71 tristate "Parser for BCM963XX Image Tag format partitions"
72 depends on BCM63XX || BMIPS_GENERIC || COMPILE_TEST
75 Image Tag is the firmware header used by broadcom on their xDSL line
76 of devices. It is used to describe the offsets and lengths of kernel
77 and rootfs partitions.
78 This driver adds support for parsing a partition with an Image Tag
79 header and creates up to two partitions, kernel and rootfs.
82 tristate "ARM Firmware Suite partition parsing"
83 depends on (ARM || ARM64)
85 The ARM Firmware Suite allows the user to divide flash devices into
86 multiple 'images'. Each such image has a header containing its name
89 If you need code which can detect and parse these tables, and
90 register MTD 'partitions' corresponding to each image detected,
93 You will still need the parsing functions to be called by the driver
94 for your particular device. It won't happen automatically. The
95 'physmap' map driver (CONFIG_MTD_PHYSMAP) does this, for example.
98 tristate "Parser for TRX format partitions"
99 depends on MTD && (BCM47XX || ARCH_BCM_5301X || COMPILE_TEST)
101 TRX is a firmware format used by Broadcom on their devices. It
102 may contain up to 3/4 partitions (depending on the version).
103 This driver will parse TRX header and report at least two partitions:

108 depends on MTD_NAND_SHARPSL || MTD_NAND_TMIO || COMPILE_TEST

111 table from the NAND flash of Sharp SL Series (Zaurus) and the MTD
112 partition parser using this code.

115 tristate "RedBoot partition table parsing"
117 RedBoot is a ROM monitor and bootloader which deals with multiple
118 'images' in flash devices by putting a table one of the erase
119 blocks on the device, similar to a partition table, which gives
120 the offsets, lengths and names of all the images stored in the

124 MTD 'partitions' corresponding to each image in the table, enable
127 You will still need the parsing functions to be called by the driver
128 for your particular device. It won't happen automatically. The
129 SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
134 config MTD_REDBOOT_DIRECTORY_BLOCK
135 int "Location of RedBoot partition table"
138 This option is the Linux counterpart to the
139 CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time
142 The option specifies which Flash sectors holds the RedBoot
143 partition table. A zero or positive value gives an absolute
144 erase block number. A negative value specifies a number of
145 sectors before the end of the device.
147 For example "2" means block number 2, "-1" means the last
148 block and "-2" means the penultimate block.
150 config MTD_REDBOOT_PARTS_UNALLOCATED
151 bool "Include unallocated flash regions"
153 If you need to register each unallocated flash region as a MTD
154 'partition', enable this option.
156 config MTD_REDBOOT_PARTS_READONLY
157 bool "Force read-only for RedBoot system images"
159 If you need to force read-only for 'RedBoot', 'RedBoot Config' and
160 'FIS directory' images, enable this option.
