I was planning to do this but you got there first :)

The reason I cannot work on it anymore is that the device
requires a special signing server to flash new kernels and
I don't have access to that, and we never created a U-boot or
similar for this device so anything needed to go in through
that flashing tool.

Will you queue the patch for ARM SoC?

Yours,
Linus Walleij
