Subject: ARM: k2g: Program DDRPHY_DATX8 registers via mask and value variables
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e5e546aad18a725787e6c6b6aa1383b02eed0723;p=u-boot.git

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.
