[PATCH 0/3] HiSilicon v3xx SFC driver

[John Garry <john.garry@xxxxxxxxxx>]

This patchset introduces support for the HiSilicon SFC V3XX driver.

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.
