      stmhal: Enable two USB phys to be supported together. · 1be0fde4
      neilh10 authored
      This is refactoring to enable support for the two USB PHYs available on
      some STM32F4 processors to be used at the same time. The F405/7 & F429
      have two USB PHYs, others such as the F411 only have one PHY.
      
      This has been tested separately on a pyb10 (USB_FS PHY) and F429DISC
      (USB_HS PHY) to be able to invoke a REPL/USB.  I have modified a PYBV10
      to support two PHYs.
      
      The long term objective is to support a 2nd USB PHY to be brought up as a
      USB HOST, and possibly a single USB PHY to be OTG.

      all: Add py/mphal.h and use it in all ports. · 731f3592
      Damien George authored
      py/mphal.h contains declarations for generic mp_hal_XXX functions, such
      as stdio and delay/ticks, which ports should provide definitions for.  A
      port will also provide mphalport.h with further HAL declarations.

      py: Overhaul and simplify printf/pfenv mechanism. · 7f9d1d6a
      Damien George authored
      Previous to this patch the printing mechanism was a bit of a tangled
      mess.  This patch attempts to consolidate printing into one interface.
      
      All (non-debug) printing now uses the mp_print* family of functions,
      mainly mp_printf.  All these functions take an mp_print_t structure as
      their first argument, and this structure defines the printing backend
      through the "print_strn" function of said structure.
      
      Printing from the uPy core can reach the platform-defined print code via
      two paths: either through mp_sys_stdout_obj (defined pert port) in
      conjunction with mp_stream_write; or through the mp_plat_print structure
      which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
      on the platform.  The former is only used when MICROPY_PY_IO is defined.
      
      With this new scheme printing is generally more efficient (less layers
      to go through, less arguments to pass), and, given an mp_print_t*
      structure, one can call mp_print_str for efficiency instead of
      mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
      Thumb2 archs.

      py: Implement core of OrderedDict type. · 0ef01d0a
      Paul Sokolovsky authored
      Given that there's already support for "fixed table" maps, which are
      essentially ordered maps, the implementation of OrderedDict just extends
      "fixed table" maps by adding an "is ordered" flag and add/remove
      operations, and reuses 95% of objdict code, just making methods tolerant
      to both dict and OrderedDict.
      
      Some things are missing so far, like CPython-compatible repr and comparison.
      
      OrderedDict is Disabled by default; enabled on unix and stmhal ports.

      stmhal: Disable MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE. · ad33e246
      Damien George authored
      It uses RAM and on pyboard we are generally tight on RAM, so disable
      this optimisation for general builds.  If users need the speed then
      they can build their own version.  Maybe in the future we can have
      different versions of pyboard firmware built with different tradeoffs.

      stmhal: Collect all root pointers together in 1 place. · 3b51b3e9
      Damien George authored
      A GC in stmhal port now only scans true root pointers, not entire BSS.
      This reduces base GC time from 1700ms to 900ms.

      py: Add option to cache map lookup results in bytecode. · 7ee91cf8
      Damien George authored
      This is a simple optimisation inspired by JITing technology: we cache in
      the bytecode (using 1 byte) the offset of the last successful lookup in
      a map. This allows us next time round to check in that location in the
      hash table (mp_map_t) for the desired entry, and if it's there use that
      entry straight away.  Otherwise fallback to a normal map lookup.
      
      Works for LOAD_NAME, LOAD_GLOBAL, LOAD_ATTR and STORE_ATTR opcodes.
      
      On a few tests it gives >90% cache hit and greatly improves speed of
      code.
      
      Disabled by default.  Enabled for unix and stmhal ports.

      py: Allow builtins to be overridden. · 78d702c3
      Damien George authored
      This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
      which, when enabled, allows to override all names within the builtins
      module.  A builtins override dict is created the first time the user
      assigns to a name in the builtins model, and then that dict is searched
      first on subsequent lookups.  Note that this implementation doesn't
      allow deleting of names.
      
      This patch also does some refactoring of builtins code, creating the
      modbuiltins.c file.
      
      Addresses issue #959.
