qboot is a minimalist x86 firmware for booting Linux kernels. It does
the mininum amount of work required for the task, and it's able to
boot both PVH images and bzImages without relying on option roms.
This characteristics make it an ideal companion for the microvm

Add OpenSBI version 0.4 as a git submodule and as a prebult binary.
OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
reference implementation of the RISC-V Supervisor Binary Interface (SBI)
specifications for platform-specific firmwares executing in M-mode. For all
supported platforms, OpenSBI provides several runtime firmware examples.
These example firmwares can be used to replace the legacy riscv-pk bootloader
and enable the use of well-known bootloaders such as U-Boot.
OpenSBI is distributed under the terms of the BSD 2-clause license
("Simplified BSD License" or "FreeBSD License", SPDX: BSD-2-Clause). OpenSBI
source code also contains code reused from other projects desribed here:
https://github.com/riscv/opensbi/blob/master/ThirdPartyNotices.md.
In this case all of the code we are using from OpenSBI is BSD 2-clause
as we aren't using the Kendryte code (Apache-2.0) with QEMU and libfdt
is dual licensed as BSD 2-clause (and GPL-2.0+). OpenSBI isn't being
linked with QEMU either it is just being included with QEMU.

Here's my next pull request for qemu-4.1. I'm not sure if this will
squeak in just before the soft freeze, or just after. I don't think
it really matters - most of this is bugfixes anyway. There's some
cleanups which aren't stictly bugfixes, but which I think are safe
enough improvements to go in the soft freeze. There's no true feature
work.
Unfortunately, I wasn't able to complete a few of my standard battery
of pre-pull tests, due to some failures that appear to also be in
master. I'm hoping that hasn't missed anything important in here.
Highlights are:
* A number of fixe and cleanups for the XIVE implementation
* Cleanups to the XICS interrupt controller to fit better with the new

* Numerous fixes and improvements to TCG handling of ppc vector
instructions
* Remove a number of unnnecessary #ifdef CONFIG_KVM guards

At the moment the rtas's Makefile uses generic QEMU rules which means
that when QEMU is compiled on a little endian system, the spapr-rtas.bin
is compiled as little endian too which is incorrect as it is always
executed in big endian mode.
This enforces -mbig by defining %.o:%.S rule as spapr-rtas.bin is
a standalone guest binary which should not depend on QEMU flags anyway.

atoui() and get_index() pass char values to isdigit(). With a
standard isdigit(), we'd get undefined behavior when the value is
negative. Can't happen as char is unsigned on s390x. Even if it
ould, we're actually using isdigit() from pc-bios/s390-ccw/libc.h
here, which works fine for negative values. Clean up anyway, just
to avoid setting a bad example.

The boot method is different depending on which device type we are
booting from. Let's examine the control unit type to determine if we're
a virtio device. We'll eventually add a case to check for a real dasd device
here as well.
Since we have to call enable_subchannel() in main now, might as well
remove that call from virtio.c : run_ccw(). This requires adding some
additional enable_subchannel calls to not break calls to
virtio_is_supported().

unit type which is used to determine if we are booting a virtio device or a
real dasd device.

Introduce inline functions to convert between pointers and unsigned 32-bit
ints. These are used to hide the ugliness required to avoid compiler

Create a new header for basic architecture specific definitions and add a
mapping of low core memory. This mapping will be used by the real dasd boot
process.

Create a separate library for channel i/o related code. This decouples
channel i/o operations from virtio and allows us to make use of them for
the real dasd boot path.
