[U-Boot] [PATCH] fsl_dma: fix support for 83xx DMA engine
Commit 359ec4931944adb885882deb9b781e4095eabc94 broke support for the Freescale DMA engine on the 83xx parts. This is due to using registers which do not exist on 83xx. Remove the attribute register accesses from the 83xx build.

Hi everyone,
This never made it into mainline. I think it is a pretty obvious build error on 83xx platforms. Can someone pick it up?
Thanks, Ira

applied to u-boot-mpc83xx.
