- * TI AM335x parts define a system EEPROM that defines certain sub-fields.
- * We use these fields to in turn see what board we are on, and what
- * that might require us to set or not set.
+/**
+ * AM335X (EMIF_4D) EMIF REG_COS_COUNT_1, REG_COS_COUNT_2, and
+ * REG_PR_OLD_COUNT values to avoid LCDC DMA FIFO underflows and Frame
+ * Synchronization Lost errors. The values are the biggest that work
+ * reliably with offered video modes and the memory subsystem on the
+ * boards. These register have are briefly documented in "7.3.3.5.2
+ * Command Starvation" section of AM335x TRM. The REG_COS_COUNT_1 and
+ * REG_COS_COUNT_2 do not have any effect on current versions of
+ * AM335x.
