* counter reaches 0.
*
* These represent optimal values for common parts, it won't work for all.
* As long as you scale down, most parameters are still work, they just
* become sub-optimal. The RFR value goes in the opposite direction. If you
* don't adjust it down as your clock period increases the refresh interval
* will not be met. Setting all parameters for complete worst case may work,
* but may cut memory performance by 2x. Due to errata the DLLs need to be
* unlocked and their value needs run time calibration. A dynamic call is
* need for that as no single right value exists acorss production samples.
*
* Only the FULL speed values are given. Current code is such that rate
* changes must be made at DPLLoutx2. The actual value adjustment for low
* frequency operation will be handled by omap_set_performance()
*
* By having the boot loader boot up in the fastest L4 speed available likely
* will result in something which you can switch between.
