+Subject: [PATCH] ARM: drop !ARCH_MULTIPLATFORM dependency of XIP_KERNEL
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Enabling XIP_KERNEL requires specifying the physical address of the readonly
+memory. As these addresses vary among different SoCs and even machines with
+the same SoC enabling XIP_KERNEL might restrict the set of machines that can
+run the resulting kernel to a subset of the configured in machines.
+
+Still allowing XIP_KERNEL for a MULTIPLATFORM kernel makes sense as for some
+platforms MULTIPLATFORM is mandatory (e.g. bcm, highbank or imx). So to
+allow compiling a XIP kernel for these platforms, allow selecting XIP in the
+presence of ARCH_MULTIPLATFORM.
+
+Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+---
+This patch might be problematic for compile coverage testing according to
+Arnd. Still I need XIP for my efm32 machine as it only features 4 MiB of
+RAM.
