help
Enable SPI support for sandbox. This is an emulation of a real SPI
bus. Devices can be attached to the bus using the device tree
which specifies the driver to use. As an example, see this device
tree fragment from sandbox.dts. It shows that the SPI bus has a
single flash device on chip select 0 which is emulated by the driver
for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.
