RE: [U-Boot-Users] Problems with MPC8247, HRCW, PCI_MODCK and PLL multiplication factors

From: Ron Kellam In short, my current problem is that the PCI_MODCK bit in the SCCR register does not reflect the PCI_MODCK bit in the Hard Reset Configuration Word. Thus I can't get the clocks I want.

Sounds like the PCI is enabled in hardware, because then the MODCK_H bits in the HRCW are ignored and the MODCK_H pins on the CPU are used instead.
