aspeed/smc: Fix DMA support for AST2600 Recent firmwares uses SPI DMA transfers in U-Boot to load the different images (kernel, initrd, dtb) in the SoC DRAM. The AST2600 FMC model is missing the masks to be applied on the DMA registers which resulted in incorrect values. Fix that and wire the SPI controllers which have DMA support on the AST2600.

aspeed/smc: Fix User mode select/unselect scheme The Aspeed SMC Controller can operate in different modes : Read, Fast Read, Write and User modes. When the User mode is configured, it selects automatically the SPI slave device until the CE_STOP_ACTIVE bit is set to 1. When any other modes are configured the device is unselected. The HW logic handles the chip select automatically when the flash is accessed through its AHB window. When configuring the CEx Control Register, the User mode logic to select and unselect the slave is incorrect and data corruption can be seen on machines using two chips, witherspoon and romulus. Rework the handler setting the CEx Control Register to fix this issue.

hw/ssi: NPCM7xx Flash Interface Unit device model This implements a device model for the NPCM7xx SPI flash controller. Direct reads and writes, and user-mode transactions have been tested in various modes. Protection features are not implemented yet. All the FIU instances are available in the SoC's address space, regardless of whether or not they're connected to actual flash chips.
