Damien George 3f39d18c2b all: Add *FORMAT-OFF* in various places.
This string is recognised by uncrustify, to disable formatting in the
region marked by these comments.  This is necessary in the qstrdef*.h files
to prevent modification of the strings within the Q(...).  In other places
it is used to prevent excessive reformatting that would make the code less
readable.

The PowerPC port that runs on microwatt and qemu

This port is intended to be a minimal MicroPython port that runs in QEMU, microwatt simulator with ghdl or microwatt on Xilinx FPGA with potato UART.

Building

By default the port will be built for the host machine:

$ make

Cross compilation for POWERPC

If you need to cross compilers you'll want to grab a powerpc64le compiler (not powerpc or powerpc64).

On Ubuntu (18.04) you'll want:

$ apt install gcc-powerpc64le-linux-gnu

(Use CROSS_COMPILE=powerpc64le-linux-gnu-)

If your distro doesn't have cross compilers, you can get cross compilers here:

(Avoid musl libc as it defines __assert_fail() differently to glibc which breaks the micropython powerpc code)

Then do:

$ make CROSS_COMPILE=<compiler prefix>

Building will produce the build/firmware.bin file which can be used QEMU or microwatt.

To run in QEMU use:

$ ./qemu-system-ppc64 -M powernv -cpu POWER9 -nographic -bios build/firmware.bin
