I pulled these in from current Linux Mainline. I added SPDX headers and 
reformatted some lines to for line length (but I have reverted the line 
lengths in my follow-up patch).

I renamed everything to variants of phycore_am335x_r2 as previously 
discussed.

Done, thank you for the suggestion. I also took inspiration for the data 
structure as suggested by Wadim Egorov.

Unfortunately, these defines are referenced within 
arch/arm/mach-omap2/am335x/board.c, which I would rather not want to 
break at this time.

Other than that, I implemented all points, along with some further 
refinement/clean-up.
