OK, I will remove the "iProc SoC based Machine types".  This was 
grouping all iProc based SoCs under one menu and parallels what the 
existing "Broadcom Mobile Soc Support" menu does.
I can create another patch removing the "Broadcom Mobile SoC Support" 
menu if the ARM Maintainer now want all Broadcom devices are supposed to 
be contained in a single level?
