Right. The usual naming is to use 'mach-*' for one platform, and 'plat-*'
for stuff that spreads multiple 'mach-*' directories. In this case, the
name I would expect is either 'mach-bcm' as Christian suggested, or
'mach-brcm' if people have strong opinions in favor of that, but not
'plat-brcm'.

Yes, of course.

I'll let you work that out with Stephen and Christian. I think just
'mach-bcm' is sufficent, but I think the three of you should come to
an agreement first.
