To be nominated, the vga\n arbiter and platform hooks must not have nominated a default. A\n card will then only be nominated if it has a driver attached and\n has IO or memory decoding enabled.\n\n - adds relevant documentation.\n\nThe practical impact of this is improved X autoconfiguration on some\narm64 systems.\n\nChanges in v3:\n\n - Add documentation - thanks Daniel Vetter for pointing it out.\n\n - Clarify explanations. Thanks to everyone for continuing to bear\n with my incomplete understanding of PCI and provide some clarity.\n\n - Split refactoring and adding functionality.\n\nChanges in v2: https://www.spinics.net/lists/linux-pci/msg64007.html\n\nDrop all the powerpc patches.
