from the backing chain.

Introduce a per-request flag for copy-on-read so that a block device can
process both regular and copy-on-read requests.  Overlapping reads and

Currently on the pseries machine the SLOF firmware is used normally,
but we bypass it when -kernel is specified.  Having these two

different boot paths can cause some confusion.

In particular at present we need to "probe" the (emulated) PCI bus and
produce device tree nodes for the PCI devices in qemu, for the -kernel
case.  In the SLOF case, it takes the device tree from qemu adds some
stuff to it then passes it on to the kernel.

It's been decided that a better approach is to always boot through
SLOF, even when using -kernel.  WIth this approach we can leave PCI
probing and device node creation to SLOF in all cases which removes a
bunch of code in qemu, and avoids iterating the PCI devices from the
machine specific init code which we're not supposed to do.

This patch changes qemu to always boot through SLOF, and not to create
PCI nodes.  Simultaneously it updates the included version of SLOF
(submodule and binary image) to one which supports (and requires) the
new approach.

The new SLOF version also includes a number of unrelated enhancements:
support for booting from virtio-pci devices and e1000, greatly
improved FCode support and many bugfixes.  It also makes SLOF ready to

virtio-pci: Fix endianness of virtio config

The virtio config area in PIO space is a bit special. The initial
header is little endian but the rest (device specific) is guest
native endian.

The PIO accessors for PCI on machines that don't have native IO ports
assume that all PIO is little endian, which works fine for everything
except the above.

A complicated way to fix it would be to split the BAR into two memory
regions with different endianess settings, but this isn't practical
to do, besides, the PIO code doesn't honor region endianness anyway
(I have a patch for that too but it isn't necessary at this stage).

So I decided to go for the quick fix instead which consists of
reverting the swap in virtio-pci in selected places, hoping that when
we eventually do a "v2" of the virtio protocols, we sort that out once
and for all using a fixed endian setting for everything.
