Jason J. Herne 86c58705bb s390-bios: cio error handling
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:

cio device error
  ssid  : 0x0000000000000000
  cssid : 0x0000000000000000
  sch_no: 0x0000000000000000

Interrupt Response Block Data:
    Function Ctrl : [Start]
    Activity Ctrl : [Start-Pending]
    Status Ctrl : [Alert] [Primary] [Secondary] [Status-Pending]
    Device Status : [Unit-Check]
    Channel Status :

- SeaBIOS (bios.bin) is the successor of pc bios.
  See http://www.seabios.org/ for more information.

- The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios
  project (http://www.nongnu.org/vgabios/).

- The PowerPC Open Hack'Ware Open Firmware Compatible BIOS is
  available at https://repo.or.cz/openhackware.git.

- OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable
  firmware implementation. The goal is to implement a 100% IEEE
  1275-1994 (referred to as Open Firmware) compliant firmware.
  The included images for PowerPC (for 32 and 64 bit PPC CPUs),
  Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built
  from OpenBIOS SVN revision 1280.

- SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware
  implementation for certain IBM POWER hardware.  The sources are at
  https://github.com/aik/SLOF, and the image currently in qemu is
  built from git tag qemu-slof-20190114.

- sgabios (the Serial Graphics Adapter option ROM) provides a means for
  legacy x86 software to communicate with an attached serial console as
  if a video card were attached.  The master sources reside in a subversion
  repository at http://sgabios.googlecode.com/svn/trunk.  A git mirror is
  available at https://git.qemu.org/git/sgabios.git.

- The PXE roms come from the iPXE project. Built with BANNER_TIME 0.
  Sources available at http://ipxe.org.  Vendor:Device ID -> ROM mapping:

	8086:100e -> pxe-e1000.rom

	1af4:1000 -> pxe-virtio.rom

- The sources for the Alpha palcode image is available from:
  https://github.com/rth7680/qemu-palcode.git

- The u-boot binary for e500 comes from the upstream denx u-boot project where
  it was compiled using the qemu-ppce500 target.
  A git mirror is available at: https://git.qemu.org/git/u-boot.git
  The hash used to compile the current version is: 2072e72

- Skiboot (https://github.com/open-power/skiboot/) is an OPAL
  (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can
  run an hypervisor OS or simply a host OS on the "baremetal"
  platform, also known as the PowerNV (Non-Virtualized) platform.

- QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to
  provide virtualised drivers for PPC MacOS guests.
