I now realized that bcm63xx's:
* Kconfig is wrapper in: if SOC_BCM63XX
* Makefile is conditional: obj-$(CONFIG_SOC_BCM63XX)

So it means I've to either:
1. Refactor bcm63xx structure
2. Make SOC_BCM63XX selectable on ARCH_BCM4908 and select it

I'm not sure if any of above is a really good idea. Any further thought, ideas?
