/*
 * 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>...]
 *
 * <mtd-def>  := <mtd-id>:<part-def>[,<part-def>...]
 * <mtd-id>   := unique device tag used by linux kernel to find mtd device (mtd->name)
 * <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
 * mtdparts=mtdparts=edb7312-nor:256k(ARMboot)ro,-(root);edb7312-nand:-(home)
