* 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
