README.440-DDR-performance

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.
*Improves the Mbit/sec for TTCP benchmark by almost 76%.
