# This is a very trickly TEMPORARY fix. Enabling ALL features exceeds BL31's
# progbits limit. We need a way to build all useful configurations while waiting
# on the fvp to increase its SRAM size. The problem is twofild:
#  1. the cleanup that introduced these enables cleaned up tf-a a little too
#     well and things that previously (incorrectly) were enabled, no longer are.
#     A bunch of CI configs build subtly incorrectly and this combo makes it
#     necessary to forcefully and unconditionally enable them here.
#  2. the progbits limit is exceeded only when the tsp is involved. However,
#     there are tsp CI configs that run on very high architecture revisions so
#     disabling everything isn't an option.
# The fix is to enable everything, as before. When the tsp is included, though,
# we need to slim the size down. In that case, disable all optional features,
# that will not be present in CI when the tsp is.
# Similarly, DRTM support is only tested on v8.0 models. Disable everything just
# for it.
# TODO: make all of this unconditional (or only base the condition on
# ARM_ARCH_* when the makefile supports it).
