+ * NOTE: This code no longer attempts to program the SDRC AC timing and MR
+ * registers. This is because the code currently cannot ensure that all
+ * L3 initiators (e.g., sDMA, IVA, DSS DISPC, etc.) are not accessing the
+ * SDRAM when the registers are written. If the registers are changed while
+ * an initiator is accessing SDRAM, memory can be corrupted and/or the SDRC
+ * may enter an unpredictable state. In the future, the intent is to
+ * re-enable this code in cases where we can ensure that no initiators are
+ * touching the SDRAM. Until that time, users who know that their use case
+ * can satisfy the above requirement can enable the CONFIG_OMAP3_SDRC_AC_TIMING
+ * option.
