Currently CONFIG_ARCH_BCM_MOBILE is used to select all (both) Broadcom mobile SoC families. Instead, use that only as a config menu switch, and define specific symbols like ARCH_BCM_281XX to select a particular SoC family. If ARCH_BCM_MOBILE is selected, all of the SoCs will be selected by default, but this way each can be disabled individually as well. Note that BCM281xx and BCM21664 both require the SMC and L2 cache control code, so that code will be built based on ARCH_BCM_MOBILE. Signed-off-by: Alex Elder <elder@linaro.org> --- v3: SMC and L2 cache code is needed by both SoC families. v2: No longer uses Kbuild's $(<modulename>-y) variable mechanism.
