Driver for DesignWare SPI controller, found on many SoCs (see compatible list in Linux device tree bindings Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml). This implementation only supports MIPS as it was the only one available for the tests, however, adding support for other architectures should require only few adjustments. Driver relies on flash/nor/spi.h to find Flash chip info. Driver internal functions support 24bit addressing mode, but due to limitations of flash/nor/spi.h, it is not used. The reported writing speed is about 60kb/s. Lint, sanitizer and valgrind reported warnings were not related to the driver.
