Damien George 7c44354592 ports: Remove def of MP_PLAT_PRINT_STRN if it's the same as the default.
To simplify config, there's no need to specify MP_PLAT_PRINT_STRN if it's
the same as the default definition in py/mpconfig.h.

Joel Stanley f03d030080 powerpc/uart: Choose which UART to use at build time, not runtime.
Microwatt may have firmware that places data in r3, which was used to
detect microwatt vs powernv.  This breaks the existing probing of the UART
type in this powerpc port.

Instead build only the appropriate UART into the firmware, selected by
passing the option UART=potato or UART=lpc_serial to the Makefile.

A future enhancement would be to parse the device tree and configure
MicroPython based on the settings.

Joel Stanley b65482ffa8 powerpc: Set better default compiler.
Most developers use a compiler which is called powerpc64le-linux-gnu-gcc.

Joel Stanley 25bc42e754 powerpc: Fix Makefile rule when linking.
The linker script was included in the "$^" inputs, causing the build to
fail:

 LINK build/firmware.elf
 powerpc64le-linux-gnu-ld: error: linker script file 'powerpc.lds' appears multiple times

As a fix the linker script is left as a dependency of the elf, but only the
object files are linked.

stijn 84fa3312cf all: Format code to add space after C++-style comment start.
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.

stijn 30840ebc99 all: Enable extra conversion warnings where applicable.
Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out
implicit floating point conversions, and add extra Travis builds using
MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found
previously.  For the unix port -Wsign-comparison is added as well but only
there since only clang supports this but gcc doesn't.

Damien George 69661f3343 all: Reformat C and Python source code with tools/codeformat.py.
This is run with uncrustify 0.70.1, and black 19.10b0.

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.

David Lechner e79424d672 ports: Allow overriding CROSS_COMPILE in a custom makefile.
Many ports already allow overriding CROSS_COMPILE.  This modifies the
remaining ports to allow it as well.

Michael Neuling 079cc940a6 powerpc: Add initial port to bare metal PowerPC arch.
Runs in microwatt (GHDL and FPGA) and qemu.

Port done initially by Michael Neuling, with help from Anton Blanchard and
Jordan Niethe.
