Subject: [PATCH] mtd: rawnand: arasan: select CONFIG_BCH

Like several other nand flash drivers, this one requires the BCH
library to be selected from Kconfig.

arm-linux-gnueabi-ld: drivers/mtd/nand/raw/arasan-nand-controller.o: in function `anfc_attach_chip':
arasan-nand-controller.c:(.text+0x894): undefined reference to `bch_init'
arm-linux-gnueabi-ld: drivers/mtd/nand/raw/arasan-nand-controller.o: in function `anfc_detach_chip':
arasan-nand-controller.c:(.text+0x98c): undefined reference to `bch_free'
arm-linux-gnueabi-ld: drivers/mtd/nand/raw/arasan-nand-controller.o: in function `anfc_read_page_hw_ecc':
arasan-nand-controller.c:(.text+0x1080): undefined reference to `bch_decode'

Fixes: 197b88fecc50 ("mtd: rawnand: arasan: Add new Arasan NAND controller")
