Use the special LUNLEN_SINGLE_LEVEL constant for post Rev A4 hardware for single byte luns. Without this change, Rev B hardware would place the single byte of lun data in byte 0 of the lun structure when it should be in byte 1. Since there are few if any devices on the market that support multiple luns in target mode, the corrupted lun field (which was only corrupted for non-zero luns) wasn't hurting us.

Fix support for 256 MB aperture sizes on chipsets such as the 845 and

2003-05-27T20:13:44Z

865. The APSIZE register has a variable-sized field of enabled bits. To figure out how many bits a specific host bridge supports, write the maximum width and see how many bits are set in the hardware. We then use this mask for setting and getting the aperture size. Prior to this, the agp(4) driver would treat an aperture size of 256 MB as 128 MB and would not allocate enough physical memory for the GART as a result.
