From d7b4731efd4d4d90224917fca1a09ccf99cd1baa Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Mon, 22 Aug 2016 12:38:39 +1200 Subject: arm: mvebu: Add support for NAND interface on A-38x The NAND interface on the Armada-38x series is similar to that on the Armada-XP. The key difference is that the NAND ECC clock ratio is provided via the DFX Server registers instead of the Core Clock.
