WARNING: some of the tests will ERASE entire MTD device which they
test. Do not use these tests unless you really know what you do.
-config MTD_CMDLINE_PARTS
- tristate "Command line partition table parsing"
- depends on MTD
- help
- Allow generic configuration of the MTD partition tables via the kernel
- command line. Multiple flash resources are supported for hardware where
- different kinds of flash memory are available.
-
- 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.
-
- The format for the command line is as follows:
-
- mtdparts=<mtddef>[;<mtddef]
- <mtddef> := <mtd-id>:<partdef>[,<partdef>]
- <partdef> := <size>[@offset][<name>][ro]
- <mtd-id> := unique id used in mapping driver/device
- <size> := standard linux memsize OR "-" to denote all
- remaining space
- <name> := (NAME)
-
- Due to the way Linux handles the command line, no spaces are
- allowed in the partition definition, including mtd id's and partition
- names.
-
- Examples:
-
- 1 flash resource (mtd-id "sa1100"), with 1 single writable partition:
- mtdparts=sa1100:-
-
- Same flash, but 2 named partitions, the first one being read-only:
- mtdparts=sa1100:256k(ARMboot)ro,-(root)
-
- If unsure, say 'N'.
-
-config MTD_OF_PARTS
- tristate "OpenFirmware partitioning information support"
- default y
- depends on OF
- help
- This provides a partition parsing function which derives
- the partition map from the children of the flash node,
- as described in Documentation/devicetree/bindings/mtd/partition.txt.
