[POWERPC] qe: Fix QUICC Engine SDMA setup errors
Chuck Meade [Tue, 27 Mar 2007 14:46:10 +0000 (10:46 -0400)]
Correct the alignment of the internal buffer used by the QUICC Engine
SDMA controller to 4Kbytes.  Correct the shift direction in the logic
that sets up the SDMR register for the QUICC Engine SDMA controller.
