The Primary-to-Sideband bus (P2SB) is used to access various peripherals through memory-mapped I/O in a large chunk of PCI space. The space is segmented into different channels and peripherals are accessed by device-specific means within those channels. Devices should be added in the device tree as subnodes of the p2sb. This adds a uclass and enables it for sandbox. Signed-off-by: NSimon Glass <sjg@chromium.org> Reviewed-by: NBin Meng <bmeng.cn@gmail.com>
