PMB can be found on BCM4908 and many other chipsets (e.g. BCM63138).
It's needed to power on and off SoC blocks like PCIe, SATA, USB.

I will do a more thorough review tonight, however do you mind moving the
driver under drives/soc/bcm/bcm63xx? The first SoC that had PMB was
63138 and that one is DSL.
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?
Well, I was thinking about thing along those lines below, it's really
about putting drivers that belong to the same SoC family in the same
basket for easier maintenance while submitting patches/pull requests
from my side.

Sounds OK to me, thanks for clarifying what approach you're OK with!
