Let me put my TI Custodian hat on and say, I've been where you are and I
have some advice.  Make a local branch (or 5) of your working but needs
re-factoring and re-cleaning tree, and start fresh from
u-boot-tegra/next.  Move more tegra20 files to the tegra common area.
Strip (#if 0) the "new" include files bare.  Bring it up again.  If you
bring in the framework so we can have <plat/foo.h> (which is in turn
arch/$(ARCH)/include/plat-vendor) I will be so happy you beat me to the
punch and with something a bit more (IMHO) clean than how the kernel
handles <plat/>.  You're masking a way a lot of things that are either
identical (which is duplication which is bad) or subtly different (and
you haven't hit it, yet).  However you migrate from the current tree to
the new tree (I've done a lot of ugly steps when I've done this locally,
but it keeps the board working from change to change), do it and do it
sooner rather than later.  You will thank yourself in the end.
