// The following macros are supported (use comma to separate macros):

// The MemClk pins are identified based on BKDG definition of Fn2x88[MemClkDis] bitmap.
// AGESA will base on this value to disable unused MemClk to save power.
// Example:
// BKDG definition of Fn2x88[MemClkDis] bitmap for AM3 package is like below:
// Bit AM3/S1g3 pin name
// 0 M[B,A]_CLK_H/L[0]
// 1 M[B,A]_CLK_H/L[1]
// 2 M[B,A]_CLK_H/L[2]
// 3 M[B,A]_CLK_H/L[3]
// 4 M[B,A]_CLK_H/L[4]
// 5 M[B,A]_CLK_H/L[5]
// 6 M[B,A]_CLK_H/L[6]
// 7 M[B,A]_CLK_H/L[7]
// And platform has the following routing:
// CS0 M[B,A]_CLK_H/L[4]
// CS1 M[B,A]_CLK_H/L[2]
// CS2 M[B,A]_CLK_H/L[3]
// CS3 M[B,A]_CLK_H/L[5]

// AGESA will base on this value to tristate unused CKE to save power.
//
// ODT_TRI_MAP(SocketID, ChannelID, ODTTriBit0CSMap,..., ODTTriBit3CSMap)
// The ODT pins are identified based on BKDG definition of Fn2x9C_0C[ODTTri] bitmap.
// AGESA will base on this value to tristate unused ODT pins to save power.

// AGESA will base on this value to tristate unused Chip select to save power.
//
// NUMBER_OF_DIMMS_SUPPORTED(SocketID, ChannelID, NumberOfDimmSlotsPerChannel)
// Specifies the number of DIMM slots per channel.
//

//
// NUMBER_OF_CHANNELS_SUPPORTED(SocketID, NumberOfChannelsPerSocket)

//
// OVERRIDE_DDR_BUS_SPEED(SocketID, ChannelID, USER_MEMORY_TIMING_MODE, MEMORY_BUS_SPEED)
// Specifies DDR bus speed of channel ChannelID on socket SocketID.
//

// Specifies the DRAM technology type of socket SocketID (DDR2, DDR3,...)
//
// WRITE_LEVELING_SEED(SocketID, ChannelID, DimmID, Byte0Seed, Byte1Seed, Byte2Seed, Byte3Seed, Byte4Seed, Byte5Seed,
