This is another attempt to implement minimalistic
Open Firmware Client Interface in QEMU.
v8 is simplified to only support -kernel/-initrd;
this does not have early boot serial output (wait until Linux
initializes the serial console).
With this, I can boot unmodified Fedora 30 via petitboot
passed via -kernel/-initrd, the command line example is in 3/3.
A useful discussion happened esrlier:
https://lore.kernel.org/qemu-devel/f881c2e7-be92-9695-6e19-2dd88cbc63c1@ozlabs.ru/
This is based on sha1
6776047598c2 Cédric Le Goater "spapr/xive: use SPAPR_IRQ_IPI to define IPI ranges exposed to the guest".
Please comment. Thanks.
