New SoC is a78 based with gicv3 and uart over pl011. Communication interfaces are similar to Versal NET platform. System starts with AMD PLM firmware which loads TF-A(bl31) to memory, which is already configured, and jumps to it. PLM also prepare handoff structure for TF-A with information what components were load and flags which indicate which EL level SW should be started.
