/* Window types */



 * This driver provides a window for the host to access a BMC resource
 * across the BMC <-> Host LPC bus.
 * window_type: The BMC resource that the host will access through the
 * window. BMC flash and BMC RAM.
 * window_id: For each window type there may be multiple windows,
 * these are referenced by ID.
 * flags: Reserved for future use, this field is expected to be
 * zeroed.
 * addr: Address on the host LPC bus that the specified window should
 * be mapped. This address must be power of two aligned.
 * offset: Offset into the BMC window that should be mapped to the
 * host (at addr). This must be a multiple of size.
 * size: The size of the mapping. The smallest possible size is 64K.
 * This must be power of two aligned.
