From 034d2f5af1b97664381c00b827b274c95e22c397 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 19 Dec 2005 16:27:59 -0500 Subject: [PATCH] arm: fix dependencies for MTD_XIP MTD_XIP depends on having working asm/mtd-xip.h; it's not just per-architecture (arm-only, as current Kconfig would have it), but actually per-subarch as well. Introduced a new symbol (ARCH_MTD_XIP) set by arch Kconfig; MTD_XIP depends on it.
