powerpc port of Zephyr

Michael Neuling

Hi all,

Below is a basic port of Zephyr to powerpc:


It runs on both qemu and and microwatt [1]. It runs the basic tests and samples
in the repository and supports both cooperative and pre-emptive multitasking.

The patch still contains a few FIXMEs but reviews are welcome. When we are
comfortable with the patch, we'd like to create a PR so it can be considered for
inclusion in the upstream project.

The port was done by Anton Blanchard and myself.
