   in my project, I use SPI inerface (4 pin(pin must can been changed)) communicated with a 4G TF card, this card must mount in Zephyr filesystem ,  in connect SDK\ v1.5.0\zephyr\samples\subsys\fs\fat_fs , this sample can get some advice . I can use SPI read and write TF card how can i mount this card in zephyr filesystem and use file API fuctinon , would I should re-edit some read/write API fountion of Zephyr filesystem?
