In linux kernel since version 4.14.326 (release Date: 2023-09-23)
The Primary to Sideband (P2SB) bridge is an interface to some
PCI devices connected through it. In particular, SPI NOR controller
in Intel Apollo Lake SoC is one of such devices.
The main purpose of this library is to unhide P2SB device in case
firmware kept it hidden on some platforms in order to access devices
behind it.
