[U-Boot] Access to certain MPC8308 internal registers causes exception

I'm doing board bring up on a design using an MPC8308 and I'm seeing odd behavior when I try to read certain internal registers on the processor. In particular when I try to read the reserved registers in the DMA engine (for example offset 0xyyy2c008, right after the DMAES register) causes a ma
