18#  This makefile containts rules for  building ATF image for Trusty.
19#  It is expected that it will be included by the project that requres ATF
20#  support and the caller will configure the following variables:
21#
22#      ATF_ROOT       - Root of arm-trusted-firmware project
23#      ATF_BUILD_BASE - location that will be used to store temp files and
24#                       build results.
25#      ATF_PLAT       - ATF platform to build
26#      ATF_DEBUG      - ATF debug level
27#      ATF_WITH_TRUSTY_GENERIC_SERVICES - Add Trusty generic services
28#      ATF_TOOLCHAIN_PREFIX - AArch64 toolchain to use for building ATF
29#
30#  The following variable is returned to the caller:
31#      ATF_OUT_DIR    - Directory containing ATF images
32#      ATF_BUILD_BASE - location that will be used to store temp files and
33#                       build results.
