This patch series adds MSCC SPI flash driver. The VCore III SoCs can access directly the flash through memory, this direct mapping is working only for read functions. The other operations are going through SPI driver.
This improves the read performace by a factor of 4.75. This patch series is based on u-boot-mips/next.
