5e4ed1fd0f39e7e6c6a05021451fc2e6a98a8b72 rtas: Integrate RTAS blob
We implement RTAS as a simple binary blob which calls directly into QEMU
via a custom hcall. So far we were relying on QEMU putting the RTAS blob
to the guest memory with its location in linux,rtas-base/rtas-size.
The problems with this are:
1. we need to peek a location in the guest ram in addition to slof, FDT
and sometime kernel and init ram disk; having one less image makes QEMU's
life easier.
2. for secure VMs, it is yet another image which needs to be signed and
verified.
This implements "instantiate-rtas" completely in SLOF, including KVM PR
support ("broken sc1").
