This patch series aims to porting ASPEED FMC/SPI memory controller driver with spi-mem interface. spi-mem dirmap framework is also synchronized from Linux. These patches have been verified on both AST2600 and AST2500 EVBs.
Changes in v2: - Separate defconfig files from the SPI driver patch. - Use "if (CONFIG_IS_ENABLED(SPI_DIRMAP))" to wrap spi_dirmap related functions. - Add Winbond w25q512jv flash ID.
Changes in v3: - Get AHB bus clock frequency from the function parameter. - Fix a grammatical error in spi-mem.h.
Changes in v4: - Fix bug when SPI_NOR_4B_OPCODES flag is set.
