Yes, many of the IP blocks are for example DesignWare IPs, or ARM IPs
in the case of the Cortex-A based variants.

I also like mach-berlin a bit more than mach-mve88de3xxx, for a very
silly reason: when during a discussion you have to say mach-mv88de3xxx,
it's pretty annoying. We already have the horrible mach-mv78xx0, let's
not add more of this :)

That'd be nice indeed.
