Allow generic configuration of the [31mCONFIG_MTD[0m 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'.

Image Tag is the firmware header used by broadcom on their xDSL line
of devices. It is used to describe the offsets and lengths of kernel
and rootfs partitions.
This driver adds support for parsing a partition with an Image Tag
header and creates up to two partitions, kernel and rootfs.

depends on ([31mCONFIG_ARM[0m || [31mCONFIG_ARM64[0m)
help
The [31mCONFIG_ARM[0m Firmware Suite allows the user to divide flash devices into
multiple 'images'. Each such image has a header containing its name
and offset/size etc.
If you need code which can detect and parse these tables, and
register [31mCONFIG_MTD[0m 'partitions' corresponding to each image detected,
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
'physmap' map driver (CONFIG_MTD_PHYSMAP) does this, for example.

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 [31mCONFIG_MTD_REDBOOT_PARTS[0m
tristate "RedBoot partition table parsing"
help
RedBoot is a [31mCONFIG_ROM[0m 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
[31mCONFIG_MTD[0m '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.

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. [31mCONFIG_A[0m zero or positive value gives an absolute
erase block number. [31mCONFIG_A[0m 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.
