config CPU bool "Enable CPU drivers using Driver Model" help This allows drivers to be provided for CPUs and their type to be specified in the board's device tree. For boards which support multiple CPUs, then normally have to be set up in U-Boot so that they can work correctly in the OS. This provides a framework for finding out information about available CPUs and making changes. config CPU_IMX bool "Enable i.MX CPU driver" depends on CPU && ARM64 help Support CPU cores for SoCs of the i.MX series. config CPU_MPC83XX bool "Enable MPC83xx CPU driver" depends on CPU && MPC83xx select CLK_MPC83XX help Support CPU cores for SoCs of the MPC83xx series. config CPU_RISCV bool "Enable RISC-V CPU driver" depends on CPU && RISCV help Support CPU cores for RISC-V architecture. config CPU_MICROBLAZE bool "Enable Microblaze CPU driver" depends on CPU && MICROBLAZE select DM_EVENT select XILINX_MICROBLAZE0_PVR help Support CPU cores for Microblaze architecture.
