043dc4dd0c minimal/Makefile: Set linker to $(CC).
Changed 'LD = gcc' too 'LD = $(CC)' to support other compilers.

d6d8722558 extmod: Make extmod.mk self-contained.
This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.

Make all extmod variables (src, flags, etc) private to extmod.mk.

Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.

Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

17f2783e4a all: Use += rather than = everywhere for CFLAGS/LDFLAGS/LIBS.
This avoids a surprise where an = can cancel out an earlier +=.

6ecdf1a240 tests/frozen: Move frozentest.mpy from ports/ to tests/.
frozentest.mpy was previously duplicated in ports/minimal and
ports/powerpc.

This needs to be re-generated on every .mpy version increase, so might as
well just have a single copy of it.

9c6fd974f7 minimal/Makefile: Avoid terminal reset, use BUILD variable.
stty can provide the current terminal settings, so that they can be
stored in a shell variable and restored after running the firmware. This
avoids the complete "blanking" of the terminal, and thus also removes the
need for the sleep call.

The run target now references the firmware file using the BUILD variable
instead of using the hard coded "build/" path.

fdfe4eca74 ports: Always include debug information in the ELF.
For bare metal ARM & xtensa targets, passing -g will make the ELF file
larger but doesn't change the binary size.  However, this means tools like
gdb, addr2line, etc can extract source-level information from the ELF.

Also standardise -ggdb to -g, these produce the exact same ELF file on
arm-none-eabi-gcc and will use DWARF format for all these ports.

68f46342aa shared/runtime/pyexec: Use MP_REGISTER_ROOT_POINTER().
This uses MP_REGISTER_ROOT_POINTER() to register repl_line
instead of using a conditional inside of mp_state_vm_t.

81dbea1ce3 shared/readline: Use MP_REGISTER_ROOT_POINTER().
This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root
pointer array used by shared/readline.c and removes the registration from
all mpconfigport.h files.

This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

c9c55032dc minimal/Makefile: Don't force a 32-bit build.
Word-size specific configuration is now done automatically, so it no longer
requires this to match the ARM configuration.

Also it's less common to have 32-bit compilation support installed, so this
will make it work "out of the box" for more people.

8e591d412a minimal: Make build more flexible and work as 64-bit build.
Changes are:
- string0 is no longer built when building for host as the target, because
  it'll be provided by the system libc and may in some cases clash with the
  system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
  both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
  from mpconfigport.h to make the configuration a bit more minimal, eg as
  a better starting point for new ports.

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.

Enabled on: bare-arm, minimal, unix coverage/dev/minimal, stm32, esp32,

to test the code when the feature is disabled (the default case).

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.

b45f9de809 bare-arm, minimal: Set CSUPEROPT=-Os to get minimal firmware size.
This option affects py/vm.c and py/gc.c and using -Os gets them compiling a
bit smaller, and small firmware is the aim of these two ports.  Also,
having these files compiled with -Os on these ports, and -O3 as the default
on other ports, gives a better understanding of code-size changes when
making changes to these files.

999733b1fb minimal: Use soft float for CROSS=1 Cortex-M4 target.
When compiled with hard float the system should enable FP access when it
starts or else FP instructions lead to a fault.  But this minimal port does
not enable (or use) FP and so, to keep it minimal, switch to use soft
floating point.  (This became an issue due to the recent commit
34c04d2319 which saves/restores FP registers
in the NLR state.)

the Makefile now uses $(PY_CORE_O).

9df6451ec5 ports/{bare-arm,minimal}/Makefile: Only build with core source files.
These ports don't need anything from extmod so don't include those files
at all in the build.  This speeds up the build by about 10% when building
with a single core.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
