All Rank Refresh (ALLRKREF):
This configuration bit enables (by default) that all the
ranks are refreshed in a staggered/atomic fashion. If set,
the ranks are refreshed in an independent fashion.
Refresh Enable (REFEN):
Refresh is enabled.
DDR Initialization Done (INITDONE):
Indicates that DDR initialization is complete.
DRAM Refresh Hysteresis (REFHYSTERISIS):
Hysteresis level - Useful for dref_high watermark cases.
The dref_high flag is set when the dref_high watermark
level is exceeded, and is cleared when the refresh count
is less than the hysteresis level. This bit should be set to
a value less than the high watermark level.
DRAM Refresh Panic Watermark (REFPANICWM):
When the refresh count exceeds this level, a refresh
request is launched to the scheduler and the dref_panic
flag is set.
DRAM Refresh High Watermark (REFHIGHWM):
When the refresh count exceeds this level, a refresh
request is launched to the scheduler and the dref_high
flag is set.
DRAM Refresh Low Watermark (REFLOWWM):
When the refresh count exceeds this level, a refresh
request is launched to the scheduler and the dref_low
flag is set.
