From 30e78c055265a09f5614c729133189e5b0ec6bbf Mon Sep 17 00:00:00 2001 From: Vishnu Banavath Date: Wed, 26 Oct 2022 09:44:21 +0100 Subject: [PATCH] arm-bsp/optee: register DRAM1 for N1SDP target N1SDP has 2 DRAM's. This change is to register 2nd DRAM which starts at 0x8080000000. Linux uses 1KB of this memory to share data with optee-os.
