I completely agree that per-SoC defconfigs are extremely useful. I 
attempted to do so for Cygnus and would like to for other Broadcom SoCs 
as well. Unfortunately Arnd's policy was one defconfig per company. This 
prevents use from doing so. Broadcom has a variety of SoCs and families. 
Some share technology, others are entirely different. On the projects I 
work with we don't use multi_v7_defconfig nor do our customers. We use 
per SoC defconfigs.

So, as it stands bcm_defconfig is of little use to us. We are able to 
upstream everything into the kernel except for the defconfig file. We 
are forced to maintain these internally. Yet we are able to upstream dts 
files which are per board...
