From f0aa1254776cbc0406d9b0b794479490799c3c47 Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Thu, 16 May 2019 13:03:57 +0300 Subject: [PATCH] arm: mvebu: fix ahci mbus config in SPL SPL does not initialize mbus_dram_info. Don't change the ahci mbus settings of the ROM. This allows the ahci to work in SPL.
