Hello,

The QEMU PowerNV machine was first designed to start with a skiboot
firmware at 0x0, which then loads a kernel and ramfs acting as a boot
loader. Support of the POWER processor improving in QEMU, it has been
possible to support other firmwares.

These changes add support for firmwares mapped at a different address
than 0x0. First two patches are fixes/cleanups and the last one adds a
"hb-mode" option to the machine for this purpose. It needs some
discussion to see how we want to activate this new mode.

Thanks,

C.

Applied to ppc-for-5.0, thanks.
