      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.
