New Revision: 209024
URL: http://svn.freebsd.org/changeset/base/209024
Log:
Merge from tbemd branch:
Introduce MACHINE_CPUARCH. Many different MACHINE_ARCHs will be built
from one MACHINE_CPUARCH. This will allow us to move to a more
standard MACHINE_ARCH for mips and arm which exist in many different
endian variants, and for powerpc where both 32 and 64 bit binaries are
generated from the same sources.
Reviewed by: arch@ (mostly silence though)
