* The following macros are supported (use comma to separate macros):
*
* MEMCLK_DIS_MAP(SocketID, ChannelID, MemClkDisBit0CSMap,..., MemClkDisBit7CSMap)
* 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]
* Then platform can specify the following macro:
* MEMCLK_DIS_MAP(ANY_SOCKET, ANY_CHANNEL, 0x00, 0x00, 0x02, 0x04, 0x01, 0x08, 0x00, 0x00)
*
* CKE_TRI_MAP(SocketID, ChannelID, CKETriBit0CSMap, CKETriBit1CSMap)
* The CKE pins are identified based on BKDG definition of Fn2x9C_0C[CKETri] bitmap.
* 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.
*
* CS_TRI_MAP(SocketID, ChannelID, CSTriBit0CSMap,..., CSTriBit7CSMap)
* The Chip select pins are identified based on BKDG definition of Fn2x9C_0C[ChipSelTri] bitmap.
* 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_CHIP_SELECTS_SUPPORTED(SocketID, ChannelID, NumberOfChipSelectsPerChannel)
* Specifies the number of Chip selects per channel.
*
* NUMBER_OF_CHANNELS_SUPPORTED(SocketID, NumberOfChannelsPerSocket)
* Specifies the number of channels per socket.
*
* OVERRIDE_DDR_BUS_SPEED(SocketID, ChannelID, USER_MEMORY_TIMING_MODE, MEMORY_BUS_SPEED)
* Specifies DDR bus speed of channel ChannelID on socket SocketID.
*
* DRAM_TECHNOLOGY(SocketID, TECHNOLOGY_TYPE)
* Specifies the DRAM technology type of socket SocketID (DDR2, DDR3,...)
*
* WRITE_LEVELING_SEED(SocketID, ChannelID, DimmID, Byte0Seed, Byte1Seed, Byte2Seed, Byte3Seed, Byte4Seed, Byte5Seed,
* Byte6Seed, Byte7Seed, ByteEccSeed)
* Specifies the write leveling seed for a channel of a socket.
*
* HW_RXEN_SEED(SocketID, ChannelID, DimmID, Byte0Seed, Byte1Seed, Byte2Seed, Byte3Seed, Byte4Seed, Byte5Seed,
* Byte6Seed, Byte7Seed, ByteEccSeed)
* Speicifes the HW RXEN training seed for a channel of a socket
