2019-10-04	spapr: Stop providing RTAS blob	Alexey Kardashevskiy	1	-0/+0
	SLOF implements one itself so let's remove it from QEMU. It is one less image and simpler setup as the RTAS blob never stays in its initial place anyway as the guest OS always decides where to put it.

2011-04-01	Implement hcall based RTAS for pSeries machines	David Gibson	1	-0/+0
	On pSeries machines, operating systems can instantiate "RTAS" (Run-Time Abstraction Services), a runtime component of the firmware which implements a number of low-level, infrequently used operations. On logical partitions under a hypervisor, many of the RTAS functions require hypervisor privilege. For simplicity, therefore, hypervisor systems typically implement the in-partition RTAS as just a tiny wrapper around a hypercall which actually implements the various RTAS functions. This patch implements such a hypercall based RTAS for our emulated pSeries machine. A tiny in-partition "firmware" calls a new hypercall, which looks up available RTAS services in a table.
