Currently fsl_elbc_nand doesn't initialize mtd->name, and this causes nand_get_flash_type() to assign name that is equal to chip type, like this: root@b1:~# cat /proc/mtd dev: size erasesize name mtd0: 00800000 00010000 "fe000000.flash" mtd1: 02000000 00004000 "NAND 32MiB 3,3V 8-bit" mtd0 is physmap_of flash (normal name), and mtd1 is fsl_elbc_nand. Despite inconsistency, with mtd name like this specifying paritions from the kernel command line becomes a torture (though, I didn't tried and not sure if mtdparts= can handle spaces at all). Plus, this causes real bugs when multiple fsl_elbc_nand chips registered. With this patch applied fsl_elbc_nand chip will have proper name: root@b1:~# cat /proc/mtd dev: size erasesize name mtd0: 00800000 00010000 "fe000000.flash" mtd1: 02000000 00004000 "e0600000.flash" p.s. We can't use priv->dev->bus_id as in physmap_of, because fsl_elbc_nand pretends to be a localbus controller, so its bus_id is "address.localbus", which is incorrect and thus will also not work for multiple chips.
