Hi,
This is a refinement of the Xen loader I posted a few weeks ago. Rather than complicate the generic loader with extra options I went for the more expedient approach of adding a completely new device called the guest-loader. As it didn't need to deal with any of the subtleties of the generic-loader it also worked out somewhat simpler.
Instead of allowing the user to hand hack FDT blobs we simply add syntactic sugar that understands the difference between a kernel and initrd. This could be expanded in future if we want although at the moment I don't know what else you would add.
The new syntax is now simpler:
-device guest-loader,addr=0x42000000,kernel=Image,bootargs="console=hvc0 earlyprintk=xen" \ -device guest-loader,addr=0x47000000,initrd=rootfs.cpio
So any objections? It would be nice to get in this cycle but we only have a week left until soft-freeze.
Alex Bennée (4): hw/board: promote fdt from ARM VirtMachineState to MachineState hw/riscv: migrate fdt field to generic MachineState device_tree: add qemu_fdt_setprop_string_array helper hw/core: implement a guest-loader to support static hypervisor guests

The use of FDT's is quite common across our various platforms. To allow the generic loader to tweak it we need to make it available in the generic state. This creates the field and migrates the initial user to use the generic field. Other boards will be updated in later patches.

This seems fine to me.
Do you mind writing some documentation though? The generic-loader documentation should be a good place to start.
