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
According to the MPC8260 User's Manual, PCI_MODE signal should be
reflected in SCCR register, and local bus pins configuration is taken
from HRCW and appears in SIUMCR. For some reason it does not work
this way, so the only possibility to detect if the board is
configured in PCI mode is to check the BCSR. This patch sets SCCR and
SIUMCR according to the BCSR.
