[U-Boot] davinci_dm355evm_config -make error

Hi all

The u-boot ti git source code (u-boot-ti) does not seem to build for the dm355evm. I'm getting a "lowlevel_init.S:619:2: error: #error "Unknown DDR configuration!!!" after : make davinci_dm355evm_config make

Before I correct this am I missing something?
