Yes, of course. If your board is supported by U-Boot you have to  put
your  clock  configuration  somewhere  in  the U-Boot code. Best idea
seems to be the board directory.

Yes, of course. What else? If they are supported by U-Boot  you  have
to  put  their clock configuration somewhere in the U-Boot code. Best
idea seems to be the board directory.

There is no real need for an  #ifdef  hell.  I  agree  that  we  have
already  more than enough #ifdef's, but every now and then some parts
get cleaned up. And you can make a good contribution by avoiding  the
necessity  of  new #ifdefs by helping to implement a clean separation
of CPU and board dependend code.

If you don't throw in your board specific stuff  your  board  is  not
supported  by the public version of U-Boot. Which means you will have
to maintain your own version,  and  to  make  sure  to  publish  your
"private" version according to the GPL.

As you can see, I do.
