17.5.8.2.2 Burst Refresh

When burst refresh is enabled (RFSHCTL0.refresh_burst > 0), the UDDRC issues refreshes in bursts of (RFSHCTL0.refresh_burst+1) refreshes at one time. Bursting refreshes reduce the total latency associated with those refreshes by reducing the number of precharges and activates required for refresh, as banks must be precharged only once to perform the entire group of refreshes, instead of once for each refresh.
