PATCH 1/2 ARM: mvebu: add appended DTB support in mvebu_v5_defconfig

The mvebu_v5_defconfig is currently used for Kirkwood platforms, and in the future hopefully used for Orion5x platforms. Those platforms use fairly old bootloaders that don't have Device Tree support, so it makes sense to enable appended DTB support by default, as well as the backward compatibility with ATAGS passed by the bootloader for those platforms. It helps having a defconfig that works fine out of the box for most Kirkwood platforms.

PATCH 2/2 ARM: mvebu: add devtmpfs to mvebu_v5_defconfig

The devtmpfs filesystem is now widely used and generally needed to boot Linux systems. 42 ARM defconfigs have it enabled, so it makes sense to have it enabled as well in mvebu_v5_defconfig.

I have Debian sid on my boxes, and they is quite happy without devtmpfs. Hence i've not proposed such a patch before.

Hi Thomas

Acked-by Andrew Lunn <[email protected]>

And a minor nit. Jason would like to see kirkwood in the subject, instead of mvebu, so we have a simple way to filter patches by SoC in mvebu.

Both applied to mvebu/defconfig with Andrew's Ack.

thx,

Jason.
