From: Michael Rolnik <mrolnik@gmail.com>

AVR core types are:

  - avr1
  - avr2
  - avr25
  - avr3
  - avr31
  - avr35
  - avr4
  - avr5
  - avr51
  - avr6
  - avrtiny
  - xmega2
  - xmega3
  - xmega4
  - xmega5
  - xmega6
  - xmega7

Each core type covers multiple AVR MCUs, mentioned in the comments
before definition of particular AVR core type (part of this patch).

AVR core type defines shared features that are valid for all AVR
MCUs belonging in that type.
