527 Say Y here to include the GRPCI Host Bridge Driver. The GRPCI
528 PCI host controller is typically found in GRLIB SPARC32/LEON
529 systems. The driver has one property (all_pci_errors) controlled
530 from the bootloader that makes the GRPCI to generate interrupts
531 on detected PCI Parity and System errors.

546 help
547 If you say Y, the OpenPROM device tree will be available as a
548 virtual file system, which you can mount to /proc/openprom by "mount
549 -t openpromfs none /proc/openprom".
550
551 To compile the /proc/openprom support as a module, choose M here: the
552 module will be called openpromfs.
553
554 Only choose N if you know in advance that you will not need to modify
555 OpenPROM settings on the running system.
