[U-Boot] [PATCH 09/13] board: ti: am574x-idk: Add ddr data support

Lokesh Vutla
2017-12-18T09:34:21Z

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.
