Pull up following revision(s) (requested by skrll in ticket #742): sys/arch/arm/arm32/pmap.c: revision 1.388 sys/arch/arm/arm32/armv7_generic_space.c: revision 1.11 sys/arch/arm/arm/cpufunc.c: revision 1.176 sys/arch/arm/conf/Makefile.arm: revision 1.54 (via patch) sys/arch/arm/include/arm32/pmap.h: revision 1.161 Fix the armv[67] memory attributes for uncached memory. Previously it was mapped as strongly-ordered which meant that unaligned accesses would fault. armv7_generic_bs_map now maps pages with PMAP_DEV which is treated as SO bus_dma continues to use PMAP_NOCACHE as appropriate, but this now get mapped to the correct memory attribute bits for armv[67] DEVMAP_ENTRY usees a new flag PTE_DEV. The workaround for the unaligned access faults is now removed. XXX Other armv[67] boards bus_space implementations should be checked. XXX There is scope to reduce the difference to aarch64
