| Broadcom uses a custom way of storing U-Boot environment variables. |
| They are placed inside U-Boot partition itself at unspecified offset. |

| config MTD_CMDLINE_PARTS |

| 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'. |

| The ARM Firmware Suite allows the user to divide flash devices into |

| RedBoot is a ROM monitor and bootloader which deals with multiple |

| the offsets, lengths and names of all the images stored in the |
| flash. |

| The option specifies which Flash sectors holds the RedBoot |
| partition table. A zero or positive value gives an absolute |
