[PATCH qemu] spapr/rtas: Reserve space for RTAS blob and log

2020-03-15 Thread Alexey Kardashevskiy
At the moment SLOF reserves space for RTAS and instantiates the RTAS blob which is 20 bytes binary blob calling an hypercall. The rest of the RTAS area is a log which SLOF has no idea about but QEMU does. This moves RTAS sizing to QEMU and this overrides the size from SLOF. The only remaining prob
