Introduce Socionext F_OSPI controller driver. This controller is used to
communicate with slave devices such as SPI Flash memories. It supports
4 slave devices and up to 8-bit wide bus, but supports master mode only.
This driver uses spi-mem framework for SPI flash memory access, and
can only operate indirect access mode and single data rate mode.

Thanks for your patch, which is now commit 1b74dd64c8612619
("spi: Add Socionext F_OSPI SPI flash controller driver") in
spi/for-next.
Thank you for your work.

On which systems is this hardware block found?
Perhaps this should depend on ARCH_UNIPHIER || COMPILE_TEST?
This IP doesn't depend on ARCH_UNIPHIER, so I expect that it can be widely
applied not only to ARCH_UNIPHIER.
If COMPILE_TEST is required, the dependency is like SPI_CADENCE_XSPI:
depends on (OF || COMPILE_TEST) && HAS_IOMEM
Thank you,
