From 63051d62b894b47e6aa3f59756be46513a450742 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 2 Sep 2020 08:29:10 +0200 Subject: [PATCH] mips: octeon: octeon_ebb7304: Add DDR4 support This patch adds the board specific configuration (struct) for the Octeon 3 EBB7304 EVK. This struct is ported from the 2013er Cavium / Marvell U-Boot repository. Also, the Octeon RAM driver is enabled in the board defconfig for its usage. Tested with one and two DIMMs on the EBB7304 EVK (8 & 16 GiB).
