commit 603362b4a58393061dcfed1c7f0d0fd4aba61126 upstream.
drivers/mtd/maps/ixp4xx.c requires MTD_CFI_BE_BYTE_SWAP to be set in order to compile.
drivers/mtd/maps/ixp4xx.c:57:4: error: #error CONFIG_MTD_CFI_BE_BYTE_SWAP required
This patch avoids the #error output by enforcing the policy in Kconfig. Not sure if this is the right approach, but it helps doing randconfig builds.
