14 * Added support for reading flash partition table from environment.
15 * Parsing routines are based on driver/mtd/cmdline.c from the linux 2.4
16 * kernel tree.

Wolfgang Denk700a0c62005-08-08 01:03:24 +020041 * Three environment variables are used by the parsing routines:
42 *
43 * 'partition' - keeps current partition identifier
44 *
45 * partition := <part-id>
46 * <part-id> := <dev-id>,part_num
47 *
Wolfgang Denk8f79e4c2005-08-10 15:14:32 +020048 *
Wolfgang Denk700a0c62005-08-08 01:03:24 +020049 * 'mtdids' - linux kernel mtd device id <-> u-boot device id mapping
50 *
51 * mtdids=<idmap>[,<idmap>,...]
52 *
53 * <idmap> := <dev-id>=<mtd-id>
Kyungmin Park1a7f8cc2008-08-27 14:45:20 +090054 * <dev-id> := 'nand'|'nor'|'onenand'<dev-num>
Wolfgang Denk700a0c62005-08-08 01:03:24 +020055 * <dev-num> := mtd device number, 0...
56 * <mtd-id> := unique device tag used by linux kernel to find mtd device (mtd->name)
57 *
58 *
59 * 'mtdparts' - partition list
60 *
61 * mtdparts=mtdparts=<mtd-def>[;<mtd-def>...]
62 *
63 * <mtd-def> := <mtd-id>:<part-def>[,<part-def>...]
64 * <mtd-id> := unique device tag used by linux kernel to find mtd device (mtd->name)
65 * <part-def> := <size>[@<offset>][<name>][<ro-flag>]
66 * <size> := standard linux memsize OR '-' to denote all remaining space
67 * <offset> := partition start offset within the device
68 * <name> := '(' NAME ')'
69 * <ro-flag> := when set to 'ro' makes partition read-only (not used, passed to kernel)
70 *
71 * Notes:
72 * - each <mtd-id> used in mtdparts must albo exist in 'mtddis' mapping
73 * - if the above variables are not set defaults for a given target are used
74 *
75 * Examples:
76 *
77 * 1 NOR Flash, with 1 single writable partition:
78 * mtdids=nor0=edb7312-nor
79 * mtdparts=mtdparts=edb7312-nor:-
80 *
81 * 1 NOR Flash with 2 partitions, 1 NAND with one
82 * mtdids=nor0=edb7312-nor,nand0=edb7312-nand
83 * mtdparts=mtdparts=edb7312-nor:256k(ARMboot)ro,-(root);edb7312-nand:-(home)
