+Subject: [PATCH] ARM: stm32f249-disco: don't force init= in /chosen/bootargs
+
+There is no reason to override the kernel's default init= value, as
+this breaks userspace that assumes the kernel default of /init is
+used. Since stm32 is often used with a minimal bootloader
+(afboot-stm32) that doesn't provide any mechanism to override the DTB,
+we need to adjust the kernel command line in the Device Tree source.

-Subject: [PATCH] ARM: configs: Add new config fragment to change RAM start
- point
-
-Rather than duplicate a defconfig for each difference
-between platforms, we can choose to pick a basic defconfig and
-manipulate it at run-time using config fragments. Here we're
-adding a new fragment to over-ride the RAM start point to 0x0.
