e750dfcca1 hv_exc: Improve multi-core scalability
The HV tick polling now only runs on CPU#0. All CPUs have the 1000Hz
HV tick, but secondaries only use it to poll the FIQ state and that path
does not take the BHL if no other FIQ was pending.

fabe27e3f1 memory: Remap some carveouts as uncached
This fixes display DART real-time cache hits causing AMCC exceptions.

The relevant carve-outs have flags 0x60004016; 0x60004002 is used for
DCP which is non-realtime, so I'm guessing the '16' means we should map
it uncached.

0ba2027e5e proxyclient: tools: add a FreeBSD loader
The differences are documented in the script itself, but the main odd
bit is that we pass the provided kernel as an initramfs.  Our modified
loader will probe for the initramfs start/end props in FDT and put up
a memdisk that we load the kernel from.  This choice was made for two
reasons:

1.) Avoid ad-hoc interpretations of a memory region in m1n1, it doesn't
    care if we actually passed it an initramfs or not anyways.

2.) We already had some code on hand to do this in our loader, so I
    suspect we've done similar shenanigans elsewhere anyways.

This also requires a U-Boot change to allow bootefi of an arbitrary
location, as long the size is provided.

The alignment constraints for loader/kernel were kept arbitrarily.  The
kernel will be bounced anyways by loader. I don't recall what
alignment requirements UEFI payloads have, but 2M seems reasonable.
