Some compiler warnings to deal with:

speed.c: In function 'get_sys_info':
speed.c:184:4: warning: implicit declaration of function 'get_board_ddr_clk'
speed.c: In function 'get_sys_info':
speed.c:184:4: warning: implicit declaration of function 'get_board_ddr_clk'

Do you want 'CONFIG_FSL_DDR_INTERACTIVE' turned on by default?

interactive.c: In function 'fsl_ddr_interactive':
interactive.c:1357:15: warning: variable 'len' set but not used [-Wunused-but-set-variable]

I'll look at this one.
