Legacy fatfs code being ported to ESP-IDF may use `f_gets()`, `f_puts()`,
`f_putc()`, and `f_printf()` calls, but the define `FF_USE_STRFUNC` is set to 0
without Kconfig options to enable it.
This commit retains the existing default behavior of `FF_USE_STRFUNC=0` and
adds Kconfig settings so users can configure `FF_USE_STRFUNC` and the related
`FF_PRINT_LLI`, `FF_PRINT_FLOAT`, and `FF_STRF_ENCODE` if needed.

FF_USE_TRIM is set by default with this commit. Fatfs invokes disk_ioctl
with CTRL_TRIM to erase the sectors calling sdmmc_erase_sectors to choose the right
argument for the erase operation based on media type.
This is a breaking change: applications which used diskio.h to
call ff_diskio_register, will now need to include diskio_impl.h.
Including diskio.h will include the original diskio.h header from
FatFS library.
Fixed problem with multiple mount/unmount for different devices.
Additional check for structure length included into the code.
Remove useless spaces.
Added initialization for reserved memory.

This change allows readonly FATFS to be mounted without wear levelling
support. This will provide the customers a simple way to mount FATFS images
generated on host and flashed onto the chip during factory provisioning.
Since NVS encryption is not supported yet and NVS entry size is limited,
the change will provide an easy alternative for securing the provisioning data
by just marking FATFS parition as encrypted.
This commit adds character encoding configurations in for the fatfs component.
The FF_LFN_UNICODE definition in ffconf.h can now be changed to accept UTF-8 or
UTF-16 encoded filernames. Test cases using UTF-8 encoded file paths and names in
FatFs have also been added.
Closes#1183
Replace explicit masks and shifts with bit fields when working with FATFS date and time representations. Also zero-initialize remaining members of struct tm.
Fixes https://github.com/espressif/esp-idf/issues/1369.
FATFS does not support f_stat call for drive root. When handling stat
for drive root, don't call f_stat and just return struct st with S_IFDIR
flag set.
Closes#984
- Remove ASCII-only configuration, CP437 is used instead
- Add dynamic code page configuration
See components/fatfs/src/00history.txt for FATFS changelog.
- _FS_TINY: disables per-file caches
- _FS_TIMEOUT: locking timeout for concurrent access
- _FS_LOCK: prevents operations which are not allowed on open files
Also sets _MAX_SS based on sector size configured for wear_levelling.
This reduces memory usage of FATFS if wear_levelling is using 512 byte
sectors.
