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.
