- ``ARM_PLAT_MT``: This flag determines whether the Arm platform layer has to
cater for the multi-threading ``MT`` bit when accessing MPIDR. When this flag
is set, the functions which deal with MPIDR assume that the ``MT`` bit in
MPIDR is set and access the bit-fields in MPIDR accordingly. Default value of
this flag is 0. Note that this option is not used on FVP platforms.

image for the ``fip`` target. In this case, the BL2 in the TF-A will not be
built.
