No, I don't have access on PowerPC hardware, so I didn't test it on PowerPC.

Can you change the code so that the interrupts are enabled only on i.MX? On PowerPC, the interrupts are used only for debugging.

Why is this necessary? The interrupts were enabled for all architectures before.

However, this patch is wrong as Jürgen mentioned, the SIER_FLAGS are written to the SIER register after we enable the DMA enable bits which leads to missing DMA enable bits at the end. I created a new patch to cleanup the whole interrupt flag setup. I will post it later.
