Hi,
Tested only on SPI NAND, so bind is made only for SPI NAND drivers.
If tried to test this with the SPI NOR framework but I couldn't get it to work. The SPI NOR flash didn't register with/was found by the mtdblock subsystem. I guess that is probably because the SPI NOR flash has it's own UCLASS_SPI_FLASH. There is some kind of compatibility layer (drivers/mtd/spi/sf_mtd.c) but it doesn't register a UCLASS_MTD.
Do you have any idea how to get this to work?
I think you have to try bind driver via mtd_bind(), just like I do for SPI-NAND in patch "spinand: bind mtdblock".
I see what in file drivers/mtd/spi/sf_probe.c there is struct mtd_info and also you have U_BOOT_DRIVER. Maybe try to bind there?
