littlefs library
================
The upstream source for the files in this directory is
https://github.com/ARMmbed/littlefs
To generate the separate files with lfs1 and lfs2 prefixes run the following
commands in the top-level directory of the littlefs repository (replace the
version tags with the latest/desired ones, and set `$MPY_DIR`):
git checkout v1.7.2
python2 ./scripts/prefix.py lfs1
cp lfs1*.[ch] $MPY_DIR/lib/littlefs
git reset --hard HEAD
git checkout v2.1.3
python2 ./scripts/prefix.py lfs2
cp lfs2*.[ch] $MPY_DIR/lib/littlefs
git reset --hard HEAD
