While the alternative PEI-less SEC implementation in PrePi already takes the EnableVFP PCD into account, the PrePeiCore code does not, and so we may end up triggering synchronous exception when code attempts to use FP or SIMD registers, which is permitted on AARCH64 by the spec. So enable the VFP as early as feasible if the associated PCD is set. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>
