The patch referenced below does:

- support AMD's Pb1x00 eval board, based on the Dbau1x00 support. I've tested it by loading it into the board SDRAM. It works both in big endian mode and, if you change all linker scripts to output little endian srec files and use the appropriate compiler command line, also in little endian mode

Note that the usb ohci driver doesn't yet work for me. Root hub seems to work, but any data transfer from a device fails. On the other hand, current linux mips 2.6 hangs when I load the ohci driver, so it doesn't work there too.

- fix the mii and usb commands which can dereference a null pointer when called without arguments.

- added mii routines to the au1x00 ethernet driver.

- add the objects as explicitly in the examples makefile, to avoid the use of a builtin make rule that goes directly from source to executable without going through the object files.

Btw, it seems to me that the Dbau1x00 port sets up the auxilliary PLL way too fast.
