-Subject: [PATCH] arm-bsp/u-boot: Reserve memory for SE comm
-
-The memory used by OpenAMP for communication between the SE-proxy and
-the Secure Enclave on the Corstone-1000 is being corrupted at some
-point after boot. When the PSA APIs are called from Linux, this
-results in OpenAMP errors from the SE-proxy.
-
-While u-boot should not be accessing this memory region, it's possible
-that something in Linux is. Explicitly reserve the memory in the
-u-boot device tree so that it is reported to the Linux kernel.
-
-Upstream-Status: Pending [Not submitted to upstream yet]
-Signed-off-by: Emekcan Aras <emekcan.aras@arm.com>
