## Summary
* documentation: update docs on SDMMC for ESP32|S2|S3
* boards/xtensa: add SDMMC SPI defconfig to ESP32|S2|S3 boards
* boards/xtensa/esp32: use common board source for SDMMC
* boards/xtensa: support SDMMC over SPI on ESP32-S2|S3
This PR improves SDMMC source code on Espressif Xtensa devices in the
following manner:
- Moves duplicated code from each board to a common directory, simplifying
feature maintenance.
- Adds support for SDMMC over SPI for ESP32S2 and ESP32S3 boards.
- Creates defconfig said boards.
- Updates the documentation with basic mounting and usage instructions.
## Impact
General impact is added support for SDMMC over SPI.
Impact on user: No.
Impact on build: No.
Impact on hardware: No.
Impact on documentation: Yes. Adds instructions for `sdmmc_spi` defconfig
for ESP32, ESP32S2 and ESP32S3.
Impact on security: No.
Impact on compatibility: Yes. On `esp32-wrover-kit` and `esp32-lyrat` the
defconfig has been renamed from `mmcsdspi` to `sdmmc_spi`.
## Testing
The following example can be replicated with ESP32, S2 and S3 devices.
### Building
- ./tools/configure.sh esp32s3-devkit:sdmmc_spi
- make and flash
### Running
Check mmcsd0 is available:
```
nsh> ls /dev
/dev:
console
mmcsd0
null
spi2
ttyS0
zero
```
Then, mount FAT FS and SD Card content should appear. Read and write
possible through echo and cat commands.
```
nsh> mount -t vfat /dev/mmcsd0 /mnt
nsh> ls /mnt
/mnt:
hello.txt
nsh> cat /mnt/hello.txt
Hello World
nsh>
```
### Results
It is possible to read and write data to the SD Card.
