dcb9ea7215 extmod: Add generic VFS sub-system. 
This provides mp_vfs_XXX functions (eg mount, open, listdir) which are
agnostic to the underlying filesystem type, and just require an object with
the relevant filesystem-like methods (eg .mount, .open, .listidr) which can
then be mounted.

These mp_vfs_XXX functions would typically be used by a port to implement
the "uos" module, and mp_vfs_open would be the builtin open function.

This feature is controlled by MICROPY_VFS, disabled by default.

94d87fbb30 test/extmod: Update vfs_fat tests for new OO FatFs library. 
The new version of FatFs requires a minimum of 50 blocks on the device.
Also, some tests no longer make sense with an OO vfs.

f5f4cdae89 extmod/vfs_fat: Rework so it can optionally use OO version of FatFS. 
If MICROPY_VFS_FAT is enabled by a port then the port must switch to using
MICROPY_FATFS_OO.  Otherwise a port can continue to use the FatFs code
without any changes.

f1db8a3097 qemu-arm: Don't compile tests in "REPL" mode. 
Previous to this patch the qemu-arm tests were compiled with is_relp=true
meaning that the __repl_print__ function was called for all lines of code
in the outer scope.  This is not the right behaviour for scripts that are
executed as though they were a file (eg tests).

With this fix the micropython/heapalloc_str.py test now works so it is
removed from the test blacklist.

e2e663291d py/objstr: Optimize string concatenation with empty string. 
In this, don't allocate copy, just return non-empty string. This helps
with a standard pattern of buffering data in case of short reads:

    buf = b""
    while ...:
        s = f.read(...)
        buf += s
        ...

For a typical case when single read returns all data needed, there won't
be extra allocation. This optimization helps uasyncio.

e9cb1f8077 py/objmodule: Move module init/deinit code into runtime functions. 
They are one-line functions and having them inline in mp_init/mp_deinit
eliminates the overhead of a function call, and matches how other state
is initialised in mp_init.

246f607a92 stmhal/mpconfigport.h: Reorganise the config options into groups. 
The order now follows that in py/mpconfig.h and is a bit cleaner and easier
to maintain.  No options were changed/added/removed with this patch, it's
just a reordering.

f8a022bc11 stmhal/boards/STM32L476DISC: Use external SPI flash for filesystem. 2017-01-24 17:01:53 +11:00
Damien George
d6a2d00167 stmhal: Add ability to have filesystem stored on external SPI flash. 
To use this feature a port should define MICROPY_HW_SPIFLASH_SIZE_BITS
along with x_CS, x_SCK, x_MOSI, x_MISO (x=MICROPY_HW_SPIFLASH).  This will
then use external SPI flash on those pins instead of the internal flash.

The SPI is done using the software implementation.  There is currently only
support for standard SPI (ie not dual or quad mode).

FROZEN_MPY_DIR.
