Nathan Whitehorn a4f7863238 Add kexec-based Linux shim loader for use with the firmware petitboot
loader on PS3 and POWER8 systems. This is reasonably portable to other
architectures, especially FDT-based ones, if similar features are useful
elsewhere.

Netboot support is missing for now and will be added in a future commit,
at which time loader.ps3 will be garbage collected.
