[U-Boot-Users] mpc8260 currently has no address translation - OK - but how is PCI supposed to work?

Just recently I had an attempt to use a couple of PIC NICs (pcnet & e100) on my mpc8272 target (using as mpc8260 in u-boot)
Both work correctly but only after disabling ALL cache which isn't exactly desirable, so there's all this code for the mpc8260 PCI but no traces of any BAT setups for this CPU, is anyone else using PCI devices on the mpc8260 without going all out and writing out BAT configurations, or is common practice to disable the cache?

Please use a line length of 72 or less characters. Thanks.
No, it is NOT common practice to disable the caches in general. See the README for details.
