This commit renames the NORETURN macro, indicating to the compiler
that a function does not return, into MP_NORETURN to maintain the same
naming convention of other similar macros.
To maintain compaitiblity with existing code NORETURN is aliased to
MP_NORETURN, but it is also deprecated for MicroPython v2.
This changeset was created using a similar process to
decf8e6a8b ("all: Remove the "STATIC"
macro and just use "static" instead."), with no documentation or python
scripts to change to reflect the new macro name.

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 with the potato uart for microwatt:
$ make
To instead build for a machine with LPC serial, such as QEMU powernv:
$ make UART=lpc_serial
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:
- https://toolchains.bootlin.com/ (use CROSS_COMPILE=powerpc64le-buildroot-linux-gnu-)
(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
