Yuri D'Elia 4ff990d130 build: Set -mrelax to remove trampolines while linking 
Avr GCC automatically marks all indirect calls for trampoline generation
irregardless of the target.

This can be avoided by forcing -mshort-calls or using -mrelax that
removes the trampoline at link time (after the call location has been
proven to be reachable).

This saves 510 bytes on the current build (the trampolines section is
now empty as expected).

How to prepare build env and tools

Run ./utils/bootstrap.py

bootstrap.py will now download all the "missing" dependencies into the .dependencies folder:

  • clang-format-9.0.0-noext
  • cmake-3.22.5
  • ninja-1.10.2
  • avr-gcc-7.3.0

How to build the preliminary project so far:

Now the process is the same as in the Buddy Firmware:

./utils/build.py

builds the firmware.hex in build/mmu_release

In case you'd like to build the project directly via cmake you can use an approach like this:

mkdir build
cd build
cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE=../cmake/AvrGcc.cmake
ninja

It will produce a MMU2SR_<version>.hex file.
