RE: Where to define IO ports

I think you should change the "u-boot".

NO. Linux stuff should be done in Linux.

 - include/configs/IceCube.h
 - board/icecube/icecube.h

1st, put a constant like (CFG_CS1_START, CFG_CS1_STOP, CFG_CS1_CFG) to
IceCube.h.

NO again. If you port to your own board, you should create  your  own
board  configuration  instead  of  messing  with  an existing one for
another board.

Is there a HOWTO on the subject of "creating my own board configuration"?

Do I put hooks in "make menuconfig" to enable/disable my customizations? 

I'm new to the process of building kernels, and I have been using an
off-the-shelf development board that had a supported configuration, so
my only customizations have been turning on/off preconfigured options. 
Any guidance, or the name of a more appropriate list in which to
post the question would be appreciated.

Thanks,

Ed
