powerpc/p1010rdb: nandboot: compare SVR properly
We were not comparing the SVRs properly previously. This comparison will properly shift the SVR and mask off the E bit This fixes the boot output to show the correct DDR bus width: 512 MiB (DDR3, 16-bit, CL=5, ECC off) instead of 512 MiB (DDR3, 32-bit, CL=5, ECC off) Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
