From: Nathan Lynch <nathan.lynch@xxxxxxx> Add SDXI Kconfig that includes debug and unit test options in addition to the usual tristate. SDXI_DEBUG seems necessary because DMADEVICES_DEBUG makes dmatest too verbose. One goal is to keep the bus-agnostic portions of the driver buildable without PCI(_MSI), in case non-PCI SDXI implementations come along later.
