spi: meson: Add support for Amlogic Meson SPIFC
This is a driver for the Amlogic Meson SPIFC (SPI flash controller), which is one of the two SPI controllers available on the SoC. It doesn't support DMA and has a 64-byte unified transmit/receive buffer. The device is optimized for interfacing with SPI NOR memories and allows the execution of standard operations such as read, page program, sector erase, etc. in a simplified way, toggling a bit in a dedicated register. The driver doesn't use those predefined commands and relies only on custom transfers. Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
