Subject: board: ti: am574x-idk: Add ddr data support
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=7b16de8595376e80ad6aa3fd616b39556f9e3df7;p=u-boot.git

board: ti: am574x-idk: Add ddr data support

AM574x-idk has the following DDR parts attached:
EMIF1: MT41K256M16HA (1GB with ECC)
EMIF2: MT41K256M16HA (1GB without ECC)

Enabling 2GB DDR without interleaving between EMIFs. And
enabling ECC on EMIF1.
