make: Modularize makefiles, add dependency tracking, build-type tracking Major build system rewrite. New and exciting: 1. Proper dependency tracking. All source files including header files should be properly tracked and recompiled as necessary when they are changed. 2. Build-type tracking. If the target changes from 'ram' to 'flash,' for example, the build system will force a rebuild rather than incorrectly link modules to a different address. 3. New targets: The old 'ram,' 'flash,' and 'jtag' targets have been replaced with the environment variable MAPLE_TARGET, which controls the link address. Users can either export it to their environment, or pass MAPLE_TARGET on the command-line. Once this is set, sketches can be compiled with 'make sketch,' or simply 'make.' Note: the default is MAPLE_TARGET='flash.' The target 'install' now automagically uploads the sketch to the board using the appropriate method. The 'run' target has been renamed to 'debug.' It starts an openocd gdb server. 4. Odds and ends: -Verbose and 'quiet' modes. Set V=1 for verbose compilation, the default is quiet. -Object file sizes and disassembly information is generated and placed in build/$(BOARD).sizes and build/$(BOARD).disas, respectively. -Parallel make with -j should speed things up if you have multiple cores.

# Useful tools
build-rules.mk: Add CROSS_COMPILE env var support Since toolchains other then older Code Sourcery (Mentor Graphics) might not use the arm-none-eabi triplet, make it possible to use any triplet by just setting the CROSS_COMPILE environment variable accordingly.

Enable USB auto-reset in a hard fault. Redirect thread-mode execution to a fail routine which throbs the LED to indicate a hard fault. Because the fail routine runs in thread mode with interrupts on, USB auto-reset should now work. Test by executing some bogus instruction (e.g. *(volatile int*)0xf34fdaa = 0;) and check that the auto-reset continues to work.
