Hello, This patchset adds initial support for Bitmain BM1880 SoC and Sophon Edge board. BM1880 SoC consists of a Dual Core ARM Cortex A53 Application processor subsystem, a single core RISC-V subsystem and a Tensor Processor subsystem. This patchset adds support for only ARM Cortex A53 Application processor subsystem with UART, which enables the board to boot into initramfs with 2 CPUs.
