[1/1] arm-bsp/u-boot: corstone1000: Reserve memory for RSS comm pointer access protocol commit: d65627585548985491a79f01de6f37e325efab96 Best regards,
From: Philip Puk <philip.puk@arm.com> 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.
