2019-09-09lib/spd_bin: Extend DDR4 spd informationEric Lai
From DDR4 SPD spec: Byte 4 (0x004): SDRAM Density and Banks Bits [7, 6]: 00 = 0 (no bank groups) 01 = 1 (2 bank groups) 10 = 2 (4 bank groups) 11 = reserved Bit [5, 4] : 00 = 2 (4 banks) 01 = 3 (8 banks) All others reserved Separate DDR3 and DDR4 banks. And extened capmb, rows, cols and ranks. Separate DDR3 and DDR4 ORGANIZATION/BUS_DEV_WIDTH offset.

2017-06-29lib/spd_bin: Use proper I2C addressesNico Huber
Use the plain address instead of the weird shifted encoding (e.g. if we'd use `0xa0` as address, it's actually `0x50` encoded into a write command).

2017-06-09lib/spd_bin: Print out correct SMBus SPD address in dump_spd_infoFurquan Shaikh
With change dd82edc388 (lib/spd_bin: make SMBus SPD addresses an input), SMBus SPD addresses are accepted from the mainboard and not calculated within the spd_bin library routines. Use the addr_map values to print correct address in dump_spd_info.

2017-05-27lib/spd_bin: make SMBus SPD addresses an inputAaron Durbin
Instead of assuming the mapping of dimm number to SPD SMBus address, allow the mainboard to provide its own mapping. That way, global resources of empty SPD contents aren't wasted in order to address a dimm on a mainboard that doesn't meet the current assumption.
