# This makefile contains rules for building QEMU for running Trusty.
# It is expected that it will be included by the project that uses QEMU
# and the caller will configure the following variables:
#
# QEMU_ROOT - Root of qemu project
# QEMU_BUILD_BASE - location that will be used to store temp files and
# build results.
# QEMU_ARCH - qemu arch to build
# QEMU_TARGET - targets to build, use comma to separate targets
# if multiple targets are specified.
#
# The following variable is returned to the caller:
# QEMU_BIN - resulting qemu image
# QEMU_BUILD_BASE - location that will be used to store temp files and
# build results.
#
