From: Aleksandar Markovic <amarkovic@wavecomp.com>

This is the AVR port from Michael release (merge) candidate 3.

The series can be found also in this repository:

https://github.com/AMarkovic/qemu-avr-merger-rc3

History:

Since v2:

- First patch is split into six smaller logical units (net result
  remains the same)
- Patch "hw/core/loader: Let load_elf populate the processor-specific
  flags" was redone to reflect the original intent that was lost in
  transalation between multiple autors
- Patch "hw/avr: Add helper to load raw/ELF firmware binaries" was
  corrected only in one line to rectify type of "e_flags"
- Patch "target/avr: Add section about AVR into QEMU documentation"
- Spurious <message-Id:> elements were removed
- The series was rebased to the latest code

Since v1:

- Addressed Thomas comments
- Fixed a non-critical bug in ATmega (incorrect SRAM base address)
- Added ELF parsing requested by Aleksandar
- Dropped default machine (as with the ARM port)
