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. | |

41 | * 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 | * | |
8f79e4c2 | 48 | * |
700a0c64 WD |
49 | * 'mtdids' - linux kernel mtd device id <-> u-boot device id mapping |
50 | * | |
51 | * mtdids=<idmap>[,<idmap>,...] | |
52 | * | |
53 | * <idmap> := <dev-id>=<mtd-id> | |
1a7f8cce | 54 | * <dev-id> := 'nand'|'nor'|'onenand'<dev-num> |
700a0c64 WD |
55 | * <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) | |
