Enable remoteproc command and APMU remoteproc driver to start Cortex-R52 cores from U-Boot command line. Code on the Cortex-R52 #0 can be started as follows, code on other cores can be started by passing the correct ID to 'rproc load' and 'rproc start' to select the core:
" => rproc init => rproc list 0 - Name:'rcar-apmu-cr52.0-apmu@e6170000' type:'internal memory mapped' supports: load start stop reset is_running 1 - Name:'rcar-apmu-cr52.1-apmu@e6170000' type:'internal memory mapped' supports: load start stop reset is_running 2 - Name:'rcar-apmu-cr52.2-apmu@e6170000' type:'internal memory mapped' supports: load start stop reset is_running => rproc load 0 0xeb200000 0x10000 Load Remote Processor 0 with data@addr=0xeb200000 65536 bytes: Success! => rproc start 0 "
