/* Setting _FS_READONLY to 1 defines read only configuration. This removes
/  writing functions, f_write, f_sync, f_unlink, f_mkdir, f_chmod, f_rename,
/  f_truncate and useless f_getfree. */

/* The _FS_MINIMIZE option defines minimization level to remove some functions.
/
/   0: Full function.
/   1: f_stat, f_getfree, f_unlink, f_mkdir, f_chmod, f_truncate and f_rename
/      are removed.
/   2: f_opendir and f_readdir are removed in addition to level 1.
/   3: f_lseek is removed in addition to level 2. */
