Your argument does not make sense here, if I follow your point, these
directories should have been named mach-nvidia or mach-ti respectively if I 
follow your convention (you use the vendor name, not a commercial product name)

I do understand your intent, yet you announce support for BCM281xx SoCs, and
one of your dtsi file is bcm281xx.dtsi. At least something like mach-bcmmobile
sounds better to me.

We have had the inclusion of the "socfpga" platform which is already very
badly named because it does not make it clear that it is an Altera platform and
not some generic SoC + FPGA platform.

Anyway, that's just my 2 cents.
