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'. |

|
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. |

tristate "ARM Firmware Suite partition parsing" |

depends on (ARM || ARM64) |
|
help |
|
The ARM 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 MTD '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 |

This driver will parse TRX header and report at least two partitions: |

kernel and rootfs. |

|
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 |

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. |
