Whilst the kernel tree already includes support for a "HiSilicon SFC driver", that is for different HW. Indeed, as mentioned in patch #1, the naming for that driver could be better, as it should support more memory technologies than SPI NOR (as I have been told), and it is actually known internally as FMC. As such, maybe "hisi-fmc" would have been better, but we can't change that now. I used V3XX in this driver name, as that is the unique versioning for this HW. As for the driver itself, it is quite simple. Only ACPI firmware is supported, and we assume m25p80 compatible SPI NOR part will be used. DMA is not supported, and we just use polling mode for operation completion notification. The driver uses the SPI MEM OPs. Tested against 5.4-rc4.
