// Set P6IF DRDY Timing
// Because there are 1.5T & 2.5T CAS latency in DDR1 mode, we need to use RDELAYMD-0
//
// Entry:
// EBP[29:25] = DRAM Speed, Dual_Channel
// VIA_NB2HOST_REG54[7:5] Host Frequency
// VIA_NB3DRAM_REG62[2:0] CAS Latency
//
// Modify NB_Reg:
// VIA_NB2HOST_REG54[3,1]
// VIA_NB2HOST_REG55[1]
// VIA_NB2HOST_REG60
// VIA_NB2HOST_REG61
// VIA_NB2HOST_REG62[3:0]
// VIA_NB2HOST_REG63
// VIA_NB2HOST_REG64
// VIA_NB2HOST_REG65[3:0]
// VIA_NB2HOST_REG66
// VIA_NB2HOST_REG67[5:4]
//
// Processing:
//--------------------------------------------------------------------------
// P6IF DRDY Timing Control:
// *Following algorithm to set DRDY timing
// Set P6IF DRDY Timing by the following 3 conditions:
// 1. RDELAYMD
// a.RDRPH(MD input internal timing control)
// b.CAS Latency
// RDELAYMD(1bit) = bit0 of (CL + RDRPH)
// for example: RDRPH=10b, CL3 -> F3_Rx56[5:4]=11b, 10b + 11b = 101b, RDELAYMD=1 (bit0)
// RDRPH=00b, CL2.5 -> F3_Rx56[5:4]=10b, 00b + 10b = 010b, RDELAYMD=0 (bit0)
// 2. CPU Frequency
// 3. DRAM Frequency
//
// According to above conditions, we create different tables:
// 1. RDELAYMD=0 : for integer CAS latency(ex. CL=3)
// 2. RDELAYMD=1 : for non-integer CAS latency(ex. CL=2.5)
// 3. Normal performance
// 4. Top performance :
// Using phase0 to a case has better performance.
//
// Note: The setting are related to performance and maybe affect DRAM initialize.
// Turn OFF(F2_Rx51[7]=0) this feature at csDRAMRegInitValueJ procedure.
// Turn ON(F2_Rx51[7]=1) this feature at csDRAMRegFinalValueJ procedure.
//
// If F2_Rx51[7]=0, then CPU always wait 8QW, a slower but most stable way
// If F2_Rx51[7]=1, then the timing will refer to F2_Rx60 ~ F2_Rx67,
// a fast way but may cause the system to be unstable.
//
// Coding:
// 1. RDELAYMD and user's option for performance can determine which table
// 2. CPU Frequency can get block offset of table
// 3. DRAM Frequency can get row offset of block
// 4. Set value
//
// PS: Fun2 Rx62, Rx65, Rx67 are don't care bits in 3296, CPU 266MHz doesn't be supported by 3296,
// but I still keep these bits in table to avoid the usage in future
// and do the fewest modification for code.
