[PATCH 0/3] Early Boot Allocation on Power

[Shawn Anastasio <sanastasio@xxxxxxxxxxxxxxxxxxxxx>]

Hello all,

This series enables the Xen boot time allocator on Power by parsing
the available memory regions from the firmware-provided device tree.

The device tree processing and bookkeeping code was adapted from Arm,
but it was trimmed down to exclude code for parsing Arm-specific dt
nodes.

Additionally, the final patch of the series updates the radix mmu
code to use the newly-enabled boot allocator for the Partition and
Process tables, instead of statically allocating them like was
previously done. Among other things, switching to run-time allocation
allows us to allocate a full-sized Process Table instead of the
minimal one that was previously used to keep the Xen binary size small.

Thanks,
