[U-Boot] [PATCH v2 00/26] remoteproc: Add support for R5F and DSP processors

[Lokesh Vutla]

This series addds support loading and starting for the following remote
processors:
- ARM Cortex-R5F in lockstep and split mode
- C66x DSP
- C7x DSP

Enable these remoteprocessor in AM654-evm and J721E evm.

Changes since v1:
- Reword the comments section for device_to_virt() api.
- Update the stm32_coproc driver to add size checks in device_to_virt()
  callback.
- Retain the export of rproc_elf32_sanity_check().
- Exported rproc_elf64_sanity_check()
- Added rproc_elf_sanity_check() api
- Added README for J721E.
