Add a remoteproc driver to load the firmware and boot a small Wakeup M3 processor present on TI AM33xx and AM43xx SoCs. This Wakeup M3 remote processor is an integrated Cortex M3 that allows the SoC to enter the lowest possible power state by taking control from the MPU after it has gone into its own low power state and shutting off any additional peripherals. The Wakeup M3 processor has two internal memory regions - 16 kB of unified instruction memory called UMEM used to store executable code, and 8 kB of data memory called DMEM used for all data sections. The Wakeup M3 processor executes its code entirely from within the UMEM and uses the DMEM for any data. It does not use any external memory or any other external resources. The device address view has the UMEM at address 0x0 and DMEM at address 0x80000, and these are computed automatically within the driver based on relative address calculation from the corresponding device tree IOMEM resources. These device addresses are used to aid the core remoteproc ELF loader code to properly translate and load the firmware segments through the .rproc_da_to_va ops.
