to mask these events. Platforms that enable FIQ handling in SP_MIN shall
implement the api ``sp_min_plat_fiq_handler()``. The default value is 0.
- ``SVE_VECTOR_LEN``: SVE vector length to configure in ZCR_EL3.
Platforms can configure this if they need to lower the hardware
limit, for example due to asymmetric configuration or limitations of
software run at lower ELs. The default is the architectural maximum
of 2048 which should be suitable for most configurations, the
hardware will limit the effective VL to the maximum physically supported
VL.
- ``TRUSTED_BOARD_BOOT``: Boolean flag to include support for the Trusted Board
Boot feature. When set to '1', BL1 and BL2 images include support to load
and verify the certificates and images in a FIP, and BL1 includes support
