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.
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.
Ideally suited for generating a binary externally, containing key-value pairs specific
to device manufacturers. Utility allows creation of a binary, compatible
with NVS structure, which can be separately flashed onto a new
partition. This helps device manufacturers set different values for
different devices, e.g. serial numbers, but using a single firmaware
image.
- Split SDMMC page into pages about SDMMC/SDSPI hosts and a page about
the protocol layer.
- Use autogenerated API reference instead of manually generated one.
- Add information about SDIO APIs.
