Add a sysbus_mmio_get_region() which allows users of sysbus
devices to turn a (SysBusDevice*, mmioidx) tuple into a
MemoryRegion*. This enables some useful simplifications of
devices which pass through another device's mmio region
(either directly or by implementing some kind of memory
controller device).

Use enum TCGOpcode instead of plain old int so that the name of
current op can be seen in GDB. Add a default case to switch
so that GCC does not complain about unhandled enum cases.

The first issue is the hard coded POSIX Real Time extensions library in the
libcacard/Makefile. From looking at the code it doesn't seem this is necessary
anyway. Robert Relyea seems to think it most likely isn't necessary.

The second issue was the missing exclusion of the BSD userland binary
builds from the addition of this Makefile target for the smartcard NSS
code which breaks the builds if smartcard NSS support is enabled.

cfi02 is annoying in that is ignores some address bits; we probably

The code will remap all PAMs, even if just one is updated, resulting
in reduced performance.  Wrap in a transaction to detect that those
other PAMs have not changed.

ppc maps the escc mmio region both at a fixed offset (as a sysbus area) and as part of a PCI BAR.
This crashes, since a MemoryRegion may have only one parent.  Use an alias so we have a separate
MemoryRegion for the BAR.
Signed-off-by: NAvi Kivity <avi@redhat.com>

The map/unmap code was assymetric - unmap used the local MemoryRegion while
map used isa_mmio_init(), which cannot handle dynamic mappings.

Fix by using isa_mmio_setup() and the local MemoryRegion.
