[yocto] machine arch files for Jetson TX1 (Quad-core ARMCortex-A57 MPCore Processor)

[Paul Knopf]

This is what I am thinking.

DEFAULTTUNE = "cortexa9hf"
require conf/machine/include/tune-cortexa9.inc

Does this sound right? I am using "hf" because in the crosstools-ng has
CT_ARCH_FLOAT="hard", and cortexa9 because of CT_ARCH_CPU="cortex-a9" and
CT_ARCH_TUNE="cortex-a9".

Sorry, I'm that familiar with embedded processors. Any guidance would be
greatly appreciated.

Thanks,
