SFC stands for Serial Flash Controller on some rockchip platforms such as RV1108/RK3128.
This patch add support for it with Standard,Dual,Quad mode.
What I found from the code and related kconfig, this sounds like spi-nor flash driver try to write driver under mtd with UCLASS_SPI_FLASH.
You mean I should write a UCLASS_SPI_FLASH U_BOOT_DRIVER(rockchip_sfc)which implement a dm_spi_flash_ops?
Yes, see sf_dataflash for example.
I see you updated the spi-nor framework on your spi tree these days,How about I write the sfc driver based on your spi-nor framework?
May be you can do that - certainly we need to write spi-nor, It is WIP looking for suitable design for handling spi-nor chips through MTD.
thanks!
