/* Proper autodetection of an AGP capable device requires examining
* PCI config registers to determine if the device implements extended
* PCI capabilities, and then walking the capability list as indicated
* in the PCI 2.2 and AGP 2.0 specifications, to determine if AGP
* capability is present. The procedure is outlined as follows:
*
* 1) Test bit 4 (CAP_LIST) of the PCI status register of the device
* to determine wether or not this device implements any extended
* capabilities. If this bit is zero, then the device is a PCI 2.1
* or earlier device and is not AGP capable, and we can conclude it
* to be a PCI device.
*
* 2) If bit 4 of the status register is set, then the device implements
* extended capabilities. There is an 8 bit wide capabilities pointer
* register located at offset 0x34 in PCI config space which points to
* the first capability in a linked list of extended capabilities that
* this device implements. The lower two bits of this register are
* reserved and MBZ so must be masked out.
*
* 3) The extended capabilities list is formed by one or more extended
* capabilities structures which are aligned on DWORD boundaries.
* The first byte of the structure is the capability ID (CAP_ID)
* indicating what extended capability this structure refers to. The
* second byte of the structure is an offset from the beginning of
* PCI config space pointing to the next capability in the linked
* list (NEXT_PTR) or NULL (0x00) at the end of the list. The lower
* two bits of this pointer are reserved and MBZ. By examining the
* CAP_ID of each capability and walking through the list, we will
* either find the AGP_CAP_ID (0x02) indicating this device is an
* AGP device, or we'll reach the end of the list, indicating it is
* a PCI device.
