This driver emulates the ARM AACI interface (PL041) connected to a LM4549 codec.
It enables audio playback for the Versatile/PB platform.
Limitations:
- Supports only a playback on one channel (Versatile/Vexpress)
- Supports only one TX FIFO in compact-mode or non-compact mode.
- Supports playback of 12, 16, 18 and 20 bits samples.
- Record is not supported.
- The PL041 is hardwired to a LM4549 codec.
Versatile/PB test build:
linux-2.6.38.5
buildroot-2010.11
alsa-lib-1.0.22
alsa-utils-1.0.22
mpg123-0.66
Qemu host: Ubuntu 10.04 in Vmware/OS X
Playback tested successfully with speaker-test/aplay/mpg123.

This patch adds a PCI bus to the pseries machine. This instantiates
the qemu generic PCI bus code, advertises a PCI host bridge in the
guest's device tree and implements the RTAS methods specified by PAPR
to access PCI config space. It also sets up the memory regions we
need to provide windows into the PCI memory and IO space, and
advertises those to the guest.
However, because qemu can't yet emulate an IOMMU, which is mandatory on
pseries, PCI devices which use DMA (i.e. most of them) will not work with
this code alone. Still, this is enough to support the virtio_pci device
(which probably _should_ use emulated PCI DMA, but is specced to use
direct hypervisor access to guest physical memory instead).

CPUs that are not the boot CPU need to run in spinning code to check if they
should run off to execute and if so where to jump to. This usually happens
by leaving secondary CPUs looping and checking if some variable in memory
changed.
In an environment like Qemu however we can be more clever. We can just export
the spin table the primary CPU modifies as MMIO region that would event based
wake up the respective secondary CPUs. That saves us quite some cycles while
the secondary CPUs are not up yet.
So this patch adds a PV device that simply exports the spinning table into the
guest and thus allows the primary CPU to wake up secondary ones.

v1 -> v2:
- change into MMIO scheme
- map the secondary NIP instead of 0 1:1
- only map 64MB for TLB, same as u-boot
- prepare code for 64-bit spinnings
v2 -> v3:
- remove r6
- set MAS2_M
- map EA 0
- use second TLB1 entry
v3 -> v4:
- change to memoryops
v4 -> v5:
- fix endianness bugs
v5 -> v6:
- add header
The MPIC has some funny feature where it maps different registers to an MMIO
region depending which CPU accesses them.
To be able to reflect that, we need to make OpenPIC be compiled in the target
code, so it can access cpu_single_env.

The first issue is the hard coded POSIX Real Time extensions library in the

The second issue was the missing exclusion of the BSD userland binary

code which breaks the builds if smartcard NSS support is enabled.

The memory API separates the attributes of a memory region (its size, how
reads or writes are handled, dirty logging, and coalescing) from where it
is mapped and whether it is enabled. This allows a device to configure
a memory region once, then hand it off to its parent bus to map it according
to the bus configuration.
Hierarchical registration also allows a device to compose a region out of
a number of sub-regions with different properties; for example some may be
RAM while others may be MMIO.
