+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The only v7-M platform only has some unused stubs in its
+mach/entry-macro.S file. So don't include it which allows efm32 to drop
+the file.

+Subject: [PATCH] ARM: deprecate mach/timex.h for !ARCH_MULTIPLATFORM
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+While mach/timex.h isn't used for multi-platform builds it still is for
+"normal" builds. As there are only three platforms that do something else
+than only defining CLOCK_TICK_RATE (and these are probably easy to fix),
+deprecate mach/timex.h and drop the corresponding files.

+Subject: [PATCH] ARM: make mach-xyz/Makefile.boot optional for
+ !ARCH_MULTIPLATFORM
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Makefile.boot is supposed to define zreladdr-y, params_phys-y and
+initrd_phys-y. The first one is only needed in the absence of AUTO_ZRELADDR
+and when building a zImage. The latters are only needed for bootp stuff.
+So ignore errors on including Makefile.boot and error out in the targets
+that need the corresponding settings.
+
+This makes it unnecessary to create dummy Makefile.boot files.
+

+Subject: [PATCH] ARM: new platform for Energy Micro's EFM32 Cortex-M3 SoCs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There are still some missing parts (e.g. board support, device trees),
+but with these bits added on top of this patch I can successfully boot a
+EFM32GG-DK3750 board that uses an EFM32GG990F1024.

+Subject: [PATCH] ARM: call of_clk_init from default time_init handler
+
+Most DT ARM machs require common clock providers initialized before timers.
+Currently, arch/arm machs use .init_time to call of_clk_init right before
+clocksource_of_init. This prevents to remove that callback and use the default
+one instead.
+
+This patch adds a call to of_clk_init() to the default .init_time callback
+for COMMON_CLK enabled machs to allow to remove custom callbacks where applicable.
+While at it, also reorder includes alphabetically.

+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.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There is no technical reason to not use the benefits of MULTIPLATFORM on a
+no-MMU machine and my not-yet-mainline efm32 port does work just fine with
+it. So drop the dependency.

+This behaves strange but I think is robust not to allow broken configs:
+
+When v4/v5 is selected, v6/v7 and v7m are available for enabling, too.
+When v6/v7 is selected the other choices are disabled
+When v7m is selected only v6/v7 are available for enabling.

++* EFM32 timer hardware
++
++The efm32 Giant Gecko SoCs come with four 16 bit timers. Two counters can be
++connected to form a 32 bit counter. Each timer has three Compare/Capture
++channels and can be used as PWM or Quadrature Decoder. Available clock sources
++are the cpu's HFPERCLK (with a 10-bit prescaler) or an external pin.
++
++Required properties:
++- compatible : Should be efm32,timer
++- reg : Address and length of the register set
++- clocks : Should contain a reference to the HFPERCLK
++
++Optional properties:
++- interrupts : Reference to the timer interrupt
++
++Example:
++
++timer@40010c00 {
++	compatible = "efm32,timer";
++	reg = <0x40010c00 0x400>;
++	interrupts = <14>;
++	clocks = <&cmu clk_HFPERCLKTIMER3>;
++};

+From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= <u.kleine-koenig@pengutronix.de>
+Date: Mon, 18 Nov 2013 11:40:16 +0100
+Subject: [PATCH] RFC: framebuffer: provide generic get_fb_unmapped_area
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This patch makes mmapping the simple-framebuffer device work on a no-MMU
+ARM target. The code is mostly taken from
+arch/blackfin/kernel/sys_bfin.c.
+
+Note this is only tested on this no-MMU machine and I don't know enough
+about framebuffers and mm to decide if this patch is sane. Also I'm
+unsure about the size check because it triggers if userspace page aligns
+the len parameter. (I don't know how usual it is to do, I'd say it's
+wrong, but my test program (fbtest by Geert Uytterhoeven) does it.)
+
