    SMMUv3: Abort DMA transactions · 1461ad9f

    For security DMA should be blocked at the SMMU by default
    unless explicitly enabled for a device. SMMU is disabled
    after reset with all streams bypassing the SMMU, and
    abortion of all incoming transactions implements a default
    deny policy on reset.
    This patch also moves "bl1_platform_setup()" function from
    arm_bl1_setup.c to FVP platforms' fvp_bl1_setup.c and
    fvp_ve_bl1_setup.c files.
