Cover letter [RFC 0/4] Add Ingenic X1000 SoC Support

Add support for Ingenic X1000 SoC. This patch set provides enough bits to boot a kernel to an initramfs user space.

I implemented this code during 2016. Boot stuck at "calibrating delay loop ...". Now I have fixed the issue by setting the correct irq. I do not have access to this device anymore so could not test the fix. Marking this patch series as RFC as this needs to be tested.

Test and feedback appreciated.

This series enables uart, timer and interrupt controller. As this is very minimal a static elf binary should be used as init and should be available in initramfs.
