452           Find out whether your system includes a PCI bus. PCI is the name of
453           a bus system, i.e. the way the CPU talks to the other stuff inside
454           your box.  If you say Y here, the kernel will include drivers and
455           infrastructure code to support PCI bus devices.
456 
457           CONFIG_PCI is needed for all JavaStation's (including MrCoffee),
458           CP-1200, JavaEngine-1, Corona, Red October, and Serengeti SGSC.
459           All of these platforms are extremely obscure, so say N if unsure.

483           PCI host controller is typically found in GRLIB SPARC32/LEON
484           systems. The driver has one property (all_pci_errors) controlled
485           from the bootloader that makes the GRPCI to generate interrupts

502           If you say Y, the OpenPROM device tree will be available as a
503           virtual file system, which you can mount to /proc/openprom by "mount

505 
506           To compile the /proc/openprom support as a module, choose M here: the
507           module will be called openpromfs.
