From: Philip Puk <[email protected]> This memory was used by OpenAMP to establish communication between the Secure Enclave and Trusted Services. After transitioning from OpenAMP to RSE_COMMS, this shared memory is now configured for the pointer access protocol in RSE_COMMS. Since this memory may be still used by a user-space application in linux as U-Boot is passing an EFI memory map starting from 0x80000000, this memory range should be reserved as the pointer access protocol may be enabled on corstone1000 in the future.
