devicetree: Check that fdt is not NULL in dt_available()

Up until now, for platforms that support DT, kvm-unit-tests would
unconditionally use DT to configure the system and the code made the
assumption that the fdt will always be a valid pointer.

On Arm systems that support both ACPI and DT, kvm-unit-tests plans to
follow the same convension as the Linux kernel: attempt to configure the
system using the DT first, then fallback to ACPI.

As a result, the fdt pointer can be NULL. Check for that in dt_available().

It doesn't matter if the initrd addresses are 64-bit pointers, even
when running on 32-bit arm, as long as the actual addresses fit in

lib/devicetree: Support 64 bit addresses for the initrd

The "linux,initrd-start" and "linux,initrd-end" properties encode the start
and end address of the initrd. The size of the address is encoded in the
root node #address-cells property and can be 1 cell (32 bits) or 2 cells
(64 bits). Add support for parsing a 64 bit address.

The stdout-path property in the device tree is a string of the form

least for now, ignore options as we don't act on them.

Merge branch 'ppc64/initial-drop-v7' of https://github.com/rhdrjones/kvm-unit-tests into HEAD

This series brings basic setup; starts a test's C entry point, main(),
and printf, exit, and malloc work. Three more series should follow this
one which must bring; vector support, mmu support, and smp support, at
which point I believe the framework could just evolve with the creation
of unit tests.

Tested on TCG and a P8 kvm_pr machine, and Laurent has tested it on
both a PowerMac G5 (kvm_pr) and a kvm_hv machine. I'm looking forward
to hearing more testing feedback from others though.
