Subject: [PATCH] s3c nand: parsing commad-line partitions prior to set->partitions

Current driver prevents command-line partitions from being parsed when built-in 
partitions are defined in s3c2410_nand_set object, but it is not desirable in some 
cases. This patch tries to parse commad-line partitions prior to the built-in.
