This commit enables LittleFS for MAIN and ADCS hwtest. However, no definition has been added to the dts. The increase in MAIN stack size is based on the littlefs sample. Signed-off-by: Takuya Sasaki <takuya.sasaki@spacecubics.com>
This commit fixes the issue where the return value of the API for checking the SPI IDLE state was always 0. Signed-off-by: Takuya Sasaki <takuya.sasaki@spacecubics.com>
When introducing LittleFS to the SPI NOR flash, 64 bytes of data were being transmitted and received at once to the SPI device. However, since the QSPI Core's TX/RX buffer is only 16 bytes, it was causing an overflow. This commit limits the data transmission and reception to the SPI device to 16 bytes at a time.

This commit adds an API to initialize the Data Store Flash memory of SC-OBC-A1. However, SC-OBC-A1 has two sides of Data Store Flash memory, but at present, only Data Store Flash memory 1 (SS1) can be used. The mechanism utilizing both sides is planned to be implemented in the future. Signed-off-by: Takuya Sasaki <takuya.sasaki@spacecubics.com>

This PR introduces the LittleFS file system to the flash memory used for Data Store on SC-OBC-A1. However, at this point, only one of the two flash memory chips is being utilized. Additionally, as a sample of using the File System, a boot count update feature has been added to hwtest.
