Remove the cmd_ prefix from command files
Now that they are in their own directory, we can remove this prefix. This makes it easier to find a file since the prefix does not get in the way.

* Three environment variables are used by the parsing routines:

* 'partition' - keeps current partition identifier
|

*
|
||||
* partition := <part-id>
|
||||
* <part-id> := <dev-id>,part_num
|
||||
*
|

*
|
||||
* 'mtdids' - linux kernel mtd device id <-> u-boot device id mapping
|

*
|
||||
* mtdids=<idmap>[,<idmap>,...]
|
||||
*
|
||||
* <idmap> := <dev-id>=<mtd-id>
|
||||
* <dev-id> := 'nand'|'nor'|'onenand'<dev-num>
|
||||
* <dev-num> := mtd device number, 0...
|
||||
* <mtd-id> := unique device tag used by linux kernel to find mtd device (mtd->name)
|
||||
*
|
||||
*
|
||||
* 'mtdparts' - partition list
|
||||
*
|

* mtdparts=mtdparts=<mtd-def>[;<mtd-def>...]

|

* <part-def> := <size>[@<offset>][<name>][<ro-flag>]
|

* <size> := standard linux memsize OR '-' to denote all remaining space
|
||||
* <offset> := partition start offset within the device
|

* <name> := '(' NAME ')'
|

* <ro-flag> := when set to 'ro' makes partition read-only (not used, passed to kernel)
|

*
|

* Notes:
|

* - each <mtd-id> used in mtdparts must albo exist in 'mtddis' mapping
|
||||
* - if the above variables are not set defaults for a given target are used
|
||||
*
|
||||
* Examples:
|
||||
*
|
||||
* 1 NOR Flash, with 1 single writable partition:
|
||||
* mtdids=nor0=edb7312-nor
|
||||
* mtdparts=mtdparts=edb7312-nor:-
|
||||
*
|
||||
* 1 NOR Flash with 2 partitions, 1 NAND with one
|
||||
* mtdids=nor0=edb7312-nor,nand0=edb7312-nand
