14.3.24. Boot-Time Configuration of MTD Partitions
Instead of defining a static partition map as described in section Memory Technology Devices you can define
the partitions for your flash memory at boot time using command line arguments. To do that you have to
enable the CONFIG_MTD_CMDLINE_PARTS kernel configuration option. With this option enabled, the
kernel will recognize a command line argument mtdparts and decode it as follows:
mtdparts=<mtddef>[;<mtddef]
<mtddef> := <mtd-id>:<partdef>[,<partdef>]
<partdef> := <size>[@offset][<name>][ro]
<mtd-id> := unique id used in mapping driver/device (number of flash bank)
<size> := standard linux memsize OR "-" to denote all remaining space
<name> := '(' NAME ')'
For example, instead of using a static partition map like this:
0x00000000-0x00060000 : "U-Boot"
0x00060000-0x00080000 : "Environment 1"
0x00080000-0x000A0000 : "Environment 2"
0x000A0000-0x000C0000 : "ASIC Images"
0x000C0000-0x001C0000 : "Linux Kernel"
0x001C0000-0x005C0000 : "Ramdisk Image"
0x005C0000-0x01000000 : "User Data"
you can pass a command line argument as follows:
mtdparts=0:384k(U-Boot),128k(Env1),128k(Env2),128k(ASIC),1M(Linux),4M(Ramdisk),-(User_Data)
