[U-Boot] FAT filesystem support on SPI flash

[Vasili Galka]

Dear Wolfgang,

1. So, my understanding is that fatload/fatls/etc have only MMC/SATA
support now? No support for MTD?

2. Where can I find the description of "device driver model" you
mention? When is it planned to be adopted?

Best,
Vasili
