-This is experimental, community-supported port for Cortex-M emulation as
-provided by QEMU (http://qemu.org).
-
-The purposes of this port are to enable:
-
-1. Continuous integration
- - run tests against 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.
