f24ec9fead pc-bios/s390-ccw: fix sclp_get_loadparm_ascii
The existing s390 bios gets the LOADPARM information from the system using
an SCLP call that specifies a buffer length too small to contain all the
output.

The recent fixes in the SCLP code have exposed this bug, since now the
SCLP call will return an error (as per architecture) instead of
writing partially and completing successfully.

The solution is simply to specify the full page length as the SCCB
length instead of a smaller size.

Fixes: 832be0d8a3 ("s390x: sclp: Report insufficient SCCB length")
Fixes: 9a22473c70 ("pc-bios/s390-ccw: get LOADPARM stored in SCP Read Info")

Due to lchs support merge in upstream seabios gone wrong (applied v3
instead of v4) here is another seabios snapshot update with the

 * OpenSBI upgrade to 0.5
 * Increase in the flash size of the virt board.
 * A non-functional cleanup.
 * A cleanup to our MIP handling that avoids atomics.
 
 This passes "make check" and boots OpenEmbedded for me.

0221d73ce6 seabios: update to pre-1.13 snapshot
seabios 1.13 will be released later this month.  This patch updates the
seabios submodule and binaries in qemu to a snapshot of git master.

will also make the number of changes smaller when we update to the final
1.13 release during qemu code freeze for 4.2.

v3: add ahci bugfix
v2: build binaries with gcc 4.8.5 instead of gcc 8.3.1 (rhel7).

892609056d ppc/pnv: update skiboot to v6.4
Currently we fail to boot a qemu powernv machine with a Power9
processor:

 PLAT: Detected generic platform
 PLAT: Detected BMC platform generic
 CPU: All 1 processors called in...
 CHIPTOD: Unknown TOD type !
 CHIPTOD: Failed ChipTOD detection !
 Aborting!

With v6.4 we can boot both a Power8 and Power9 powernv machine.

Built from submodule with powerpc64le-linux-gnu-gcc (Debian 8.3.0-2).

roms: Add OpenSBI version 0.4
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.

506179e421 ppc patch queue 2019-07-2
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
     XIVE code
   * Numerous fixes and improvements to TCG handling of ppc vector
     instructions
   * Remove a number of unnnecessary #ifdef CONFIG_KVM guards
   * Fix some errors in the PCI hotplug paths
   * Assorted other fixes

fad189d1f6 spapr/rtas: Force big endian compile for rtas
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.

d796588ba1 pc-bios/s390-ccw: Clean up harmless misuse of isdigit()
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().

Now that we have a Channel I/O library let's modify virtio boot code to
make use of it for running channel programs.

7b361db37b s390-bios: Factor finding boot device out of virtio code path
Make a new routine find_boot_device to locate the boot device for all
cases, not just virtio.

The error message for the case where no boot device has been specified
and a suitable boot device cannot be auto detected was specific to
virtio devices. We update this message to remove virtio specific wording.

930072d2bf s390-bios: Extend find_dev() for non-virtio devices
We need a method for finding the subchannel of a dasd device. Let's
modify find_dev to handle this since it mostly does what we need. Up to
this point find_dev has been specific to only virtio devices.

Add verbose error output for when unexpected i/o errors happen. This eases the
burden of debugging and reporting i/o errors. No error information is printed
in the success case, here is an example of what is output on error:

3083a1bbb8 s390-bios: Support for running format-0/1 channel programs
Introduce a library function for executing format-0 and format-1
channel programs and waiting for their completion before continuing
execution.

Add cu_type() to channel io library. This will be used to query control
unit type which is used to determine if we are booting a virtio device or a
real dasd device.
