From c60e1f254747ac650f8290e5debcf8ad1567584b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 13 Oct 2014 23:41:53 -0600 Subject: dm: sandbox: Add a SPI emulation uclass 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.
