-AMCC suggested to set the PMU bit to 0 for best performace on the
-PPC440 DDR controller. The 440er common DDR setup files (sdram.c &
-spd_sdram.c) are changed accordingly. So all 440er boards using
-these setup routines will automatically receive this performance
-increase.
-
-Please see below some benchmarks done by AMCC to demonstrate this
-performance changes:

-SDRAM0_CFG0[PMU] = 1 (U-Boot default for Bamboo, Yosemite and Yellowstone)

-Stream benchmark results
--------------------------------------------------------------
-This system uses 8 bytes per DOUBLE PRECISION word.
--------------------------------------------------------------
-Array size = 2000000, Offset = 0
-Total memory required = 45.8 MB.
-Each test is run 10 times, but only
-the *best* time for each is used.
--------------------------------------------------------------
-Your clock granularity/precision appears to be 1 microseconds.
-Each test below will take on the order of 112345 microseconds.
-   (= 112345 clock ticks)
-Increase the size of the arrays if this shows that you are not getting
-at least 20 clock ticks per test.
--------------------------------------------------------------
-WARNING -- The above is only a rough guideline.
-For best results, please be sure you know the precision of your system
-timer.

-SDRAM0_CFG0[PMU] = 0 (Suggested modification)
-Setting PMU = 0 provides a noticeable performance improvement *2% to
-5% improvement in memory performance.
