    For davinci soc I wanted to add "clocks" command not particularly for
SPL only
    when I move some piece of code from arc/arm/cpu/arm926ejs/cpu.c to say
    arc/arm/cpu/arm926ejs/speed.c and implement the command I get following
errors,

   arm-none-linux-gnueabi-ld: error: no memory region specified for
loadable section `.u_boot_cmd'
   make[2]: ***
[/home/plad/ti/uboot/denx_uboot/uboot-ti/u-boot-ti/spl/u-boot-spl] Error 1
   make[2]: Leaving directory
`/home/plad/ti/uboot/denx_uboot/uboot-ti/u-boot-ti/spl'
   I get these errors for SPL enabled
