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'.

RedBoot is a ROM monitor and bootloader which deals with multiple

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.
