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.
