Implement checkboard() to print current SoC variant used by a board, e.g. one of: SoC: RK3308 SoC: RK3308B SoC: RK3308B-S when U-Boot proper is running. U-Boot 2025.01-rc1 (Nov 02 2024 - 20:26:25 +0000) Model: Radxa ROCK Pi S SoC: RK3308B DRAM: 512 MiB (effective 510 MiB) Information about the SoC variant is read from GRF.
