+/*
+ * How do I program the SDRAM Timing Register (SDRAM0_TR) for a specific SDRAM or DIMM?
+ *
+ * As an example, consider a case where PC133 memory with CAS Latency equal to 2 is being
+ * used with a 200MHz 405GP. For a typical 128Mb, PC133 SDRAM, the relevant minimum
+ * parameters from the datasheet are:
+ * Tclk = 7.5ns (CL = 2)
+ * Trp = 15ns
+ * Trc = 60ns
+ * Trcd = 15ns
+ * Trfc = 66ns
+ *
+ * If we are operating the 405GP with the MemClk output frequency set to 100 MHZ, the clock
+ * period is 10ns and the parameters needed for the Timing Register are:
+ * CASL = CL = 2 clock cycles
+ * PTA = Trp = 15ns / 10ns = 2 clock cycles
+ * CTP = Trc - Trcd - Trp = (60ns - 15ns - 15ns) / 10ns= 3 clock cycles
+ * LDF = 2 clock cycles (but can be extended to meet board-level timing)
+ * RFTA = Trfc = 66ns / 10ns= 7 clock cycles
+ * RCD = Trcd = 15ns / 10ns= 2 clock cycles
+ *
+ * The actual bit settings in the register would be:
+ *
+ * CASL = 0b01
+ * PTA = 0b01
+ * CTP = 0b10
+ * LDF = 0b01
+ * RFTA = 0b011
+ * RCD = 0b01
+ *
+ * If Trfc is not specified in the datasheet for PC100 or PC133 memory, set RFTA = Trc
+ * instead. Figure 24 in the PC SDRAM Specification Rev. 1.7 shows refresh to active delay
+ * defined as Trc rather than Trfc.
+ * When using DIMM modules, most but not all of the required timing parameters can be read
+ * from the Serial Presence Detect (SPD) EEPROM on the module. Specifically, Trc and Trfc
+ * are not available from the EEPROM
