Application Notes 385 and 386 shares the same memory map and features
except the CPU is used. AN385 is supplied with Cortex-M3 CPU and AN386
is supplied with Cortex-M4.

I'd very appreciate some feedback on this (and following) patch from DT
camp, so I could incorporate them in the next attempt after merge window
closed.

Merry Christmas!
