* AST2600 Firmware SPI Memory Controller (FMC) . BMC firmware . 3 chip select pins (CE0 ~ CE2) . Only supports SPI type flash memory . different segment register interface . single, dual and quad mode.
* AST2600 SPI Flash Controller (SPI1 and SPI2) . host firmware . 2 chip select pins (CE0 ~ CE1) . different segment register interface . single, dual and quad mode.
* AST2500 Firmware SPI Memory Controller (FMC) . BMC firmware . 3 chip select pins (CE0 ~ CE2) . supports SPI type flash memory (CE0-CE1) . CE2 can be of NOR type flash but this is not supported by the driver . single, dual mode.
* AST2500 SPI Flash Controller (SPI1 and SPI2) . host firmware . 2 chip select pins (CE0 ~ CE1) . single, dual mode.
* AST2400 New Static Memory Controller (also referred as FMC) . BMC firmware . New register set . 5 chip select pins (CE0 ∼ CE4) . supports NOR flash, NAND flash and SPI flash memory. . single, dual and quad mode.
Each controller has a memory range on which flash devices contents are mapped. Each device is assigned a window that can be changed at bootime with the Segment Address Registers.
Each SPI flash device can then be accessed in two modes: Command and User. When in User mode, SPI transfers are initiated with accesses to the memory segment of a device. When in Command mode, memory operations on the memory segment of a device generate SPI commands automatically using a Control Register for the settings.
This initial patch adds support for User mode. Command mode needs a little more work to check that the memory window on the AHB bus fits the device size. It will come later when support for direct mapping is added.
Single and dual mode RX transfers are supported. Other types than SPI are not supported.

mtd: spi-nor: intel-spi: Convert to SPI MEM
The preferred way to implement SPI-NOR controller drivers is through SPI subsubsystem utilizing the SPI MEM core functions. This converts the Intel SPI flash controller driver over the SPI MEM by moving the driver from SPI-NOR subsystem to SPI subsystem and in one go make it use the SPI MEM functions. The driver name will be changed from intel-spi to spi-intel to match the convention used in the SPI subsystem.

* AST
spi: spi-mem: Convert Aspeed SMC driver to spi-mem
This SPI driver adds support for the Aspeed static memory controllers of the AST2600, AST2500 and AST2400 SoCs using the spi-mem interface.
* AST2600 Firmware SPI Memory Controller (FMC) . BMC firmware . 3 chip select pins (CE0 ~ CE2) . Only supports SPI type flash memory . different segment register interface . single, dual and quad mode.
* AST2600 SPI Flash Controller (SPI1 and SPI2) . host firmware . 2 chip select pins (CE0 ~ CE1) . different segment register interface . single, dual and quad mode.
* AST2500 Firmware SPI Memory Controller (FMC) . BMC firmware . 3 chip select pins (CE0 ~ CE2) . supports SPI type flash memory (CE0-CE1) . CE2 can be of NOR type flash but this is not supported by the driver . single, dual mode.
* AST2500 SPI Flash Controller (SPI1 and SPI2) . host firmware . 2 chip select pins (CE0 ~ CE1) . single, dual mode.
* AST2400 New Static Memory Controller (also referred as FMC) . BMC firmware . New register set . 5 chip select pins (CE0 ∼ CE4) . supports NOR flash, NAND flash and SPI flash memory. . single, dual and quad mode.
Each controller has a memory range on which flash devices contents are mapped. Each device is assigned a window that can be changed at bootime with the Segment Address Registers.
Each SPI flash device can then be accessed in two modes: Command and User. When in User mode, SPI transfers are initiated with accesses to the memory segment of a device. When in Command mode, memory operations on the memory segment of a device generate SPI commands automatically using a Control Register for the settings.
This initial patch adds support for User mode. Command mode needs a little more work to check that the memory window on the AHB bus fits the device size. It will come later when support for direct mapping is added.
Single and dual mode RX transfers are supported. Other types than SPI are not supported.

* AST2400 New Static Memory Controller (also referred as FMC) . BMC firmware . New register set . 5 chip select pins (CE0 ∼ CE4) . supports NOR flash, NAND flash and SPI flash memory. . single, dual and quad mode.
Each controller has a memory range on which flash devices contents are mapped. Each device is assigned a window that can be changed at bootime with the Segment Address Registers.
Each SPI flash device can then be accessed in two modes: Command and User. When in User mode, SPI transfers are initiated with accesses to the memory segment of a device. When in Command mode, memory operations on the memory segment of a device generate SPI commands automatically using a Control Register for the settings.
This initial patch adds support for User mode. Command mode needs a little more work to check that the memory window on the AHB bus fits the device size. It will come later when support for direct mapping is added.
Single and dual mode RX transfers are supported. Other types than SPI are not supported.
