- ``BL2U``: This is an optional build option which specifies the path to
BL2U image. In this case, the BL2U in TF-A will not be built.
-- ``BL2_AT_EL3``: This is an optional build option that enables the use of
+- ``BL2_AT_EL3``: This is an optional build option that enables the use of
BL2 at EL3 execution level.
-- ``BL2_IN_XIP_MEM``: In some use-cases BL2 will be stored in eXecute In Place
+- ``BL2_IN_XIP_MEM``: In some use-cases BL2 will be stored in eXecute In Place
(XIP) memory, like BL1. In these use-cases, it is necessary to initialize
the RW sections in RAM, while leaving the RO sections in place. This option
enable this use-case. For now, this option is only supported when BL2_AT_EL3
BL32 image for the ``fip`` target. In this case, the BL32 in TF-A will not
be built.

+- ``BL32_EXTRA1``: This is an optional build option which specifies the path to
Trusted OS Extra1 image for the ``fip`` target.
-- ``BL32_EXTRA2``: This is an optional build option which specifies the path to

Trusted OS Extra2 image for the ``fip`` target.
- ``BL32_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
- ``DEBUG``: Chooses between a debug and release build. It can take either 0
(release) or 1 (debug) as values. 0 is the default.
-- ``DYN_DISABLE_AUTH``: Enables the capability to disable Trusted Board Boot
- authentication. This option is only meant to be enabled for development
- platforms. Both TRUSTED_BOARD_BOOT and the LOAD_IMAGE_V2 flags need to be
- set if this flag has to be enabled. 0 is the default.

+ Board Boot authentication at runtime. This option is meant to be enabled only

- ``EL3_PAYLOAD_BASE``: This option enables booting an EL3 payload instead of
the normal boot flow. It must specify the entry point address of the EL3

- ``tdram`` : Trusted DRAM (if available)
- - ``dram`` : Secure region in DRAM (default option when TBB is enabled,

- ``ARM_XLAT_TABLES_LIB_V1``: boolean option to compile TF-A with version 1
of the translation tables library instead of version 2. It is set to 0 by
``checkpatch.pl``, ``spelling.txt`` and ``const_structs.checkpatch`` available
in the `Linux master tree`_ scripts directory, then set the ``CHECKPATCH``
