This is regarding SPI controller driver support in OpenBMC.

Here is the scenario: Three devices connected over same SPI controller as mentioned below:

Firmware SPI Memory Controller (BSPI): (0x1E620000):

    - Flash 0 (CS0)

    - Flash 1 (CS1)

    - MCU/CPLD (CS2)

When I look at the OpenBMC Linux repository, I could find 'aspeed-smc.c' driver under the MTD subsystem, so this seems to work only for flash devices.

Do we've any other driver support or a solution to handle all the three devices? Any help/suggestions would be appreciated.
