+         This enables support for the Intel Primary-to-Sideband bus,
+         abbreviated to P2SB. The P2SB is used to access various peripherals
+         such as eSPI, GPIO, 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. A
+         Peripheral Channel Register? (PCR) API is provided to access those
+         devices - see pcr_readl(), etc.
