U-Boot Users:
One of our engineers traced a problem with interrupts to an error in the include/ppc440.h file. It appeares that several sets of defines for the addresses of registers in the EPX and GRX universal interrupt controller are incorrect. It actually just looks like a minor cut-and-paste error resulting in, for example, "UIC0_DCR_BASE+0xXX" where "UIC2_DCR_BASE+0xXX" should have been. This bug appears to only affect the upper two sets of registers in the UIC (UIC2 and UIC3).
This correction has been tested on a sequioa board. Amoung the things this bug affects is the USB device. USB Device works correctly with the bug corrected.
[PATCH]

- Corrects bug affecting the addresses for the universal interrupt controller UIC2 and UIC3 on the PPC440 Epx, GRx, and SPE chips.
