7 -  ``ARM_BL31_IN_DRAM``: Boolean option to select loading of BL31 in TZC secured
8    DRAM. By default, BL31 is in the secure SRAM. Set this flag to 1 to load
10    sets the TSP location to DRAM and ignores the ``ARM_TSP_RAM_LOCATION`` build
13 -  ``ARM_CONFIG_CNTACR``: boolean option to unlock access to the ``CNTBase<N>``
17    kernel). Default is true (access to the frame is allowed).
19 -  ``ARM_FW_CONFIG_LOAD_ENABLE``: Boolean option to enable the loading of
25 -  ``ARM_DISABLE_TRUSTED_WDOG``: boolean option to disable the Trusted Watchdog.
26    By default, Arm platforms use a watchdog to trigger a system reset in case
33 -  ``ARM_LINUX_KERNEL_AS_BL33``: The Linux kernel expects registers x0-x3 to
35    to have a Linux kernel image as BL33 by preparing the registers to these
36    values before jumping to BL33. This option defaults to 0 (disabled). When
43 -  ``ARM_PLAT_MT``: This flag determines whether the Arm platform layer has to
49 - ``ARM_PLAT_PROVIDES_BL2_MEM_PARAMS``: This flag can be overriden to 1 in the Arm
50    platform’s ``platform.mk`` to indicate that the platform supplies its own
53    bl2_mem_params_desc.c file to ``BL2_SOURCES``.  The default value is 0.
58    State-ID yet. Hence this flag is used to configure whether to use the
60    in which case the platform is configured to expect NULL in the State-ID
68    to sign the BL2 and Trusted Key certificates. Available options for
74       and BL2 binaries. This hash corresponds to the development private key
80       and BL2 binaries. This hash corresponds to the development private key
86       the BL1 and BL2 binaries. This key corresponds to the RSA private
91       the BL1 and BL2 binaries. This key corresponds to the EC private key
102 -  ``ARM_XLAT_TABLES_LIB_V1``: boolean option to compile TF-A with version 1
103    of the translation tables library instead of version 2. It is set to 0 by
106 -  ``ARM_GPT_SUPPORT``: Enable GPT parser to get the entry address and length of
122 -  ``CSS_DETECT_PRE_1_7_0_SCP``: Boolean flag to detect SCP version
124    compatible change to the MTL protocol, used for AP/SCP communication.
125    TF-A no longer supports earlier SCP versions. If this option is set to 1
129    SCP_BL2U to the FIP and FWU_FIP respectively, and enables them to be loaded
135    is set to 1, then SCMI/SDS drivers will be used. Default is 0.
137 - ``CSS_SYSTEM_GRACEFUL_RESET``: Build option to enable graceful powerdown of
139    require all the CPUs to execute the CPU specific power down sequence to
145 - ``FVP_TRUSTED_SRAM_SIZE``: Size (in kilobytes) of the Trusted SRAM region to
146   utilize when building for the FVP platform. This option defaults to 256 with
152 -  ``JUNO_AARCH32_EL3_RUNTIME``: This build flag enables you to execute EL3
153    runtime software in AArch32 mode, which is required to run AArch32 on Juno.
154    By default this flag is set to '0'. Enabling this flag builds BL1 and BL2 in
162    which supports multi-chip operation. If ``NRD_CHIP_COUNT`` is set to any
164    to support multi-chip operation.
168   core count, cluster count or other peripherals. This build option is used to
