    dm: sandbox: Add a SPI emulation uclass · c60e1f25
    Simon Glass authored
    U-Boot includes a SPI emulation driver already but it is not explicit, and
    is hidden in the SPI flash code.
    
    Conceptually with sandbox's SPI implementation we have a layer which
    creates SPI bus transitions and a layer which interprets them, currently
    only for SPI flash. The latter is actually an emulation, and it should be
    possible to add more than one emulation - not just SPI flash.
    
    Add a SPI emulation uclass so that other emulations can be plugged in to
    support different types of emulated devices on difference buses/chip
    selects.
