Implement __flt_rounds for ARMv6 hard-float. The fpscr register stores the
current rounding mode used by the VFP unit.
Simplify how we build MACHINE_ARCH. There are 3 options that may be set
however only arm, armeb, armv6, and soon armv6hf will be used.
Add the llvm/clang patch for r263619.
Reorder the pmap macros so "ARM_MMU_V6 + ARM_MMU_V7" is first. As they are
identical this allows us to build for both v6 and v7 together.
Add code for enabling second CPU core for A20 SoC.
Enable SMP on Cubieboard2.
Switch to freebsd.org emal address in copyright.
