We currently calculate the final RTAS and FDT location based on the early estimate of the RMA size, cropped to 256M on KVM since we only know the real RMA size at reset time which happens much later in the boot process. This means the FDT and RTAS end up right below 256M while they could be much higher, using precious RMA space and limiting what the OS bootloader can put there which has proved to be a problem with some OSes (such as when using very large initrd's) Fortunately, we do the actual copy of the device-tree into guest memory much later, during reset, late enough to be able to do it using the final RMA value, we just need to move the calculation to the right place. However, RTAS is still loaded too early, so we change the code to load the tiny blob into qemu memory early on, and then copy it into guest memory at reset time. It's small enough that the memory usage doesn't matter.
