It seems that the current trend is to have the USB subsystem "know" which arch are ECHI and OHCI, versus having the board manually select the values. The current defconfig for Cavium produces the following: warning: (MIPS_ALCHEMY && CAVIUM_OCTEON_REFERENCE_BOARD && SOC_AR71XX && SOC_AR724X && SOC_AR913X && SOC_AR933X) selects USB_ARCH_HAS_EHCI which has unmet direct dependencies (USB_SUPPORT) There are a few other boards that suffix the ARCH_HAS selects with "if USB_SUPPORT", but the selection of enabling the support doesn't really change whether the arch has it or not, so go with the solution that lets the subsystem choose.
