Andrey notice how the Power is not completely in the corner,
but is not in the middle either, but also how they group

also note, PLL is right in the top corner, and, also, note
that any clock lines are (or should) be away from unrelated
high speed transients.  e.g. ULPI CLK should not be directly
next to an EINT which might be for an external button with a
lot of "bounce" on the contacts.

Staf, Jean-Paul: a 256-pin package is going to be 64 pins per side.

are there any special considerations for that?
