This patch adds support to fsusermount for multiple block devices (instead of just one). The maximum allowed is fixed at compile time by the size of the fs_user_mount array accessed via MP_STATE_PORT, which in turn is set by MICROPY_FATFS_VOLUMES. With this patch, stmhal (which is still tightly coupled to fsusermount) is also modified to support mounting multiple devices And the flash and SD card are now just two block devices that are mounted at start up if they exist (and they have special native code to make them more efficient).
