We currently generate a kernel that boots from the harddrive in the DIR-685. That's not how we usually do things, so let's augment it to boot from flash and mount the rootfs using squashfs and JFFS2 like everyone else. Partition splitting only work when the partitions are inside of a "partitions" node which is why we have a patch like this (submitted upstream). Another patch drops the rootfs arguments and renames the firmware partition while adding the compatible "wrg" to it so the WRGG parser will kick in. Factory image was tested by bravely reflashing the DIR-685 from stock firmware using the web UI and the serial console boot loader. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Subject: [PATCH 1/2] ARM: dts: gemini: Indent DIR-685 partition table
|
|
|
|
It is discouraged to have OF partitions as subnodes directly
|
|
under the device, create a "partitions" subnode and put the
|
|
partitions inside it.
