# Choose a Yocto architecture with the MACHINE variable.  Choices
# supported are:
#
# yd-arm    - ARMv6 code for older (e.g. ARM11) machines
# yd-armv7  - ARMv7-A code for newer (ARM Cortex, Krait) devices
# yd-x86    - 32 bit i586 code
# yd-x86-64 - 64 bit x86_64, use only if you have a suitable kernel!
#
# Note that Yocto allows a single build tree to span multiple
# architectures.  The last MACHINE choice is cached in ./machine.mak
# to prevent accidents like installing the wrong architecture.
