From 86ce9a340e38bcba664fb11c7ab9ba03fcf5e55e Mon Sep 17 00:00:00 2001 From: Sashka Nochkin Date: Tue, 19 Apr 2016 23:44:45 -0400 Subject: mips: mt7620: fallback to SDRAM when syscfg0 does not have a valid value for the memory type Mediatek MT7620 SoC has syscfg0 bits where it sets the type of memory being used. However, sometimes those bits are not set properly (reading "11"). In this case, the SoC assumes SDRAM. The patch below reflects that.
