# Note about _cross/_hostcc
#
# The Allwinner A64 has an "embedded controller" of sorts for managing
# peripherals when the A53 cores are turned off. This EC is a custom CPU core
# that uses the OpenRISC 1000 ISA, and it's what the Crust firmware runs
# on. or1k is the gcc platform for OpenRISC, and it has nothing to do with any
# real Void system targets. This is why the two cross-compilers are needed, or1k
# is used ONLY for the crust portion of the firmware.
