* The IRQ0 on Rev 2 is pulled high (low in Rev 1.x) to
* implement PEX10 errata. As INT is active high, it
* will cause core to take 0x500 interrupt.
*
* Due to the PIC's default pass through mode, as soon
* as interrupts are enabled (MSR[EE] = 1), an interrupt
* will be taken and u-boot will hang. This is due to a
* hardware change (per an errata fix) on new revisions
* of the board with Rev 2.x parts.
*
* Setting the PIC to mixed mode prevents the hang.
