ef20677ca6 omap_gpmc: Pull prefetch engine data into sub-struct
Refactor the gpmc state structure so items relating to
the prefetch engine are in their own sub-struct and have
more useful names.

856f2df771 omap_gpmc: Accept a zero mask field on omap3630
OMAP3630 adds an extra bit of address masking, so a mask of
0xb1111 is valid. Unfortunately the GPMC_REVISION is the same as
on the OMAP3430 which only has three bits of address masking, so
we have to derive this feature directly from the OMAP revision
rather than from the GPMC revision.

f13e656e7e hw/omap.h: Add OMAP 3630 to omap_mpu_model enumeration
Add the OMAP 3630 to the omap_mpu_model enumeration, and add the
corresponding cpu_is_omap3630() function.

(OMAP3 isn't supported yet but this is useful in upgrading common
components to be "OMAP3 ready". We already have this for OMAP3430.)

de8af7fe01 omap_gpmc: Fix handling of FIFOTHRESHOLDSTATUS bit
The OMAP3 TRM is inconsistent about whether the GPMC FIFOTHRESHOLDSTATUS
bit should be set when FIFOPOINTER > FIFOTHRESHOLD or when it is >=
FIFOTHRESHOLD. Apparently the underlying functional spec from which
the TRM was created states that the behaviour is ">=", and this also
makes more conceptual sense.

Refactor the omap_gpmc_cs_map/unmap functions:
 * take the omap_gpmc_s* and a chipselect id rather than the
   omap_gpmc_cs_file_s*, so they have access to the general gpmc
   member fields
 * extract the base and mask from the config registers in the functions
   rather than at every callsite
 * check for CSVALID in the functions rather than at every callsite

07bc2f8077 omap_gpmc: Clean up omap_gpmc_attach MemoryRegion conversion
Now that all callers of omap_gpmc_attach pass in a MemoryRegion*,
we can remove the base_update and unmap function pointer arguments,
and the opaque pointer that was passed into these callbacks.

We can also remove the base and size fields from omap_gpmc_cs_file_s
as these are no longer necessary (you don't need the base/size
to unmap a MemoryRegion the way you did to undo a mapping made
with cpu_register_physical_memory()).

0fc6b5828f Fix build on OpenBSD with BSD userland emu and smartcard NSS enabled
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.
