Hi,
On our system, we are interested in keeping all files, including the OS image and U-Boot second stage on FAT filesystem residing on a SPI flash.
I'm not a file-system expert, but I've a basic question like how does/well a SPI flash(mtd) device have FAT support on it. Generally flash file-systems were categories to do the job right?
I have not found existing U-Boot support for such functionality. Have I missed it?
In any case, I'm willing to implement this, do you see it reasonable incorporating such code into U-Boot? (if it passes review of course)
I note about design: As our chip (TI's AM335x) does not support direct boot from FAT stored on SPI, I plan reserving section at the beginning of SPI flash for the first stage boot loader and having the filesystem after it.
thanks!
