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.
