From e5e546aad18a725787e6c6b6aa1383b02eed0723 Mon Sep 17 00:00:00 2001 From: "Cooper Jr., Franklin" Date: Fri, 16 Jun 2017 17:25:21 -0500 Subject: [PATCH] ARM: k2g: Program DDRPHY_DATX8 registers via mask and value variables Different K2G evms may need to program the various KS2_DDRPHY_DATX8_X_OFFSET registers in different ways. Therefore, use the mask and val registers for each KS2_DDRPHY_DATAX_X_OFFSET to properly program the register.
