spi flash 可以通过挂载 fat 和 easyflash 吗？

这家伙很懒，什么也没写！

也可以手动新建目录，然后将分区挂载到目录下面，这是挂载lfs分区的例子
```c
void fileinit(void)
{
    struct rt_device *mtd_dev = RT_NULL;

/* 初始化 fal */
    fal_init();
    /* 生成 mtd 设备 */
    mtd_dev = fal_mtd_nor_device_create(FS_PARTITION1_NAME);
    if (!mtd_dev)
    {
        LOG_E("Can't create a mtd device on '%s' partition.", FS_PARTITION1_NAME);
    }
    else
    {
        /* 挂载 littlefs */
        if (dfs_mount(FS_PARTITION1_NAME, "/", "lfs", 0, 0) == 0)
        {
            LOG_I("Filesystem initialized!");
            mtd_dev = fal_mtd_nor_device_create(FS_PARTITION2_NAME);
            if (!mtd_dev)
            {
                LOG_E("Can't create a mtd device on '%s' partition.", FS_PARTITION2_NAME);
            }
            if (opendir("/c") == RT_NULL)
            {
                mkdir("c", 0);
            }
            if (dfs_mount(FS_PARTITION2_NAME, "/c", "lfs", 0, 0) == 0)
            {
                LOG_I("Onchip Filesystem initialized!");
            }

else
            {
                /* 格式化文件系统 */
                dfs_mkfs("lfs", FS_PARTITION2_NAME);
                if (dfs_mount(FS_PARTITION2_NAME, "/c", "lfs", 0, 0) == 0)
                    LOG_I("Onchip Filesystem initialized!");
                else
                    LOG_E("Onchip Failed to initialize filesystem!");
            }
        }
        else
        {
            /* 格式化文件系统 */
            dfs_mkfs("lfs", FS_PARTITION1_NAME);
            /* 挂载 littlefs */
            if (dfs_mount(FS_PARTITION1_NAME, "/", "lfs", 0, 0) == 0)
            {
                LOG_I("Filesystem initialized!");
            }
            else
            {
                LOG_E("Failed to initialize filesystem!");
            }
        }
    }
}
```
