Continuous integration + - run tests agains architecture-specific parts of code base +2. Experimentation + - simulation & prototyping of anything that has architecture-specific + code + - exploring instruction set in terms of optimising some part of + MicroPython or a module +3. Streamlined debugging + - no need for JTAG or even an MCU chip itself + - no need to use OpenOCD or anything else that might slow down the + process in terms of plugging things together, pressing buttons, etc. + +This port will only work with with [GCC ARM Embedded](launchpad.net/gcc-arm-embedded) +toolchain and not with CodeSourcery toolchain. You will need to modify +`LDFLAGS` if you want to use CodeSourcery's version of `arm-none-eabi`. +The difference is that CodeSourcery needs `-T generic-m-hosted.ld` while +ARM's version requires `--specs=nano.specs --specs=rdimon.specs` to be +passed to the linker.
