* Add support for SK98xx driver

* Add PCI support for SL8245 board

* Support IceCube board configurations with 1 x AMD AM29LV065 (8 MB)
  or 1 x AM29LV652 (two LV065 in one chip = 16 MB);
  Run IPB at 133 Mhz; adjust the MII clock frequency accordingly

* Set BRG_CLK on PM825/826 to 64MHz (VCO_OUT / 4, instead of 16  MHz)
  to allow for more accurate baudrate settings
  (error now 0.7% at 115 kbps, instead of 3.5% before)

* Patch by Andreas Mohr, 4 Sep 2003:
  Fix a lot of spelling errors
