ps2: use QEMU qcodes instead of scancodes
The sequence used for Pause had a small typo in the AT set 1, with a 0xe1
accidentally changed to 0x91. This is not immediately visible with Linux
guests since they run the ps2 device with AT set 2 scancodes.

This difference is pretty benign, since of all the operating systems I have

bytes anyway. This change none the less makes the ps2 device better follow real

The 'Print' key is special in the AT set 1 / set 2 scancode definitions.
An unmodified 'Print' key is supposed to send

AT Set 2: e0 12 e0 7c (Down) e0 f0 7c e0 f0 12 (Up)
which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R'
keys (which signify SysRq), the scancodes are required to follow a different
scheme. With Alt_L, the expected sequences are
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
And with Alt_R
AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up)
AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up)
It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send
AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up)
AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)
And with Alt_R
AT set 1: e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up)
AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)
The AT set 3 scancodes have no special handling for Alt-Print.
Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:
commit f2289cb6924afc97b2a75d21bfc9217024d11741

With this patch QEMU would send
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:
- The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
requested
- The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
tot he guest os (bare 0x54)
To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state
Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

Wire in ompic and add basic support for SMP. The OpenRISC is special in
that interrupts for devices are routed to each core's PIC. This is
achieved using the qemu_irq_split utility, but this currently limits
OpenRISC to 2 cores.
This models the reference architecture described in the OpenRISC spec
1.2 proposal.

The changes to the intialization of the sim include:
CPU Reset
o Reset each cpu to the bootstrap PC rather than only a single cpu as
done before.
o During Kernel loading the bootstrap PC is saved in a static global.
Network Initialization
o Connect the interrupt to each CPU
o Use more simple sysbus_mmio_map() rather than memory_region_add_subregion()

This patch updates the sun4u model to being much closer to a real Ultra 5
by moving devices behind the 2 simba PCI bridges (A and B) as found on real
hardware.
The most noticeable change introduced by this patchset is that in-built devices
are no longer attached to the PCI root bus, but instead behind PCI bridge A.
Along with this the interrupt routing is updated accordingly to match the
official documentation.
Since the existing code currently bypasses the PCI bridge interrupt
swizzling, the interrupt mapping functions are reorganised so that
pci_pbm_map_irq() is used by the PCI bridges and pci_apb_map_irq() is
used by the PCI host bridge.
Behind the sabre PCI host bridge, the PCI IO space now needs to be
split into two separate halves at 0x8000000. Therefore we also setup a new
PCI IO space region of increased size on the PCI host bridge and enable
32-bit PCI IO accesses to allow IO accesses to reach devices behind PCI
bridge B correctly.
As part of this change we also combine the onboard sunhme NIC and the ebus
into a single multi-function device as done on a real Ultra 5. For other
NICs the existing behaviour is preserved, i.e. we initialise them and
place them into the next free slot on PCI bus B.
Finally we mark the physically unavailable slots (plus slot 0 in busA) as
reserved to ensure that users can't plug devices into non-existent slots
which will break interrupt routing.
Note: since this commit changes PCI topology and interrupt routing, an
updated openbios-sparc64 binary is included with this commit containing the
associated changes to maintain bisectability.

Logical block size of a SCSI disk should never be larger than
physical block size. From an ATA/SCSI perspective, it makes no sense
to have the logical block size greater than the physical block size,
and it cannot even be effectively expressed in the command set. The
whole point of adding the physical block size to the ATA/SCSI command
set was to communicate a desire for a larger block size (than logical),
while maintaining backwards compatibility with legacy 512 byte block
size.
When setting logical_block_size > physical_block_size, QEMU cannot express
it in READ CAPACITY(16) output, and all it can do is set the physical
block exponent to 0 (i.e. logical_block_size == physical_block_size).
Reporting the error properly, however, is better.
