If you look at the function static void DDR2PhyInit(void) in bl_devam335x.c you will see this line
HWREG(DATA0_FIFO_WE_SLAVE_RATIO_0) = ((0x56 << 30)|(0x56 << 20)|(0x56<< 10)|(0x56 << 0));
I get integer operation result is out of range errors/warnings from this. I get this type of error in several places actually.
