	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.

2017-06-29	lib/spd_bin: Use proper I2C addresses	Nico 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).

2017-05-27	lib/spd_bin: make SMBus SPD addresses an input	Aaron 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.

2017-02-10	ddr3 spd: move accessor code into lib/spd_bin.c	Patrick Georgi
	It's an attempt to consolidate the access code, even if there are still multiple implementations in the code.

2016-11-30	lib: Add library to handle SPD data in CBFS or DIMM	Naresh G Solanki
	Add library to: 1. add spd.bin in cbfs, generated from mainboard/spd/*.spd.hex files. 2. runtime get spd data with spd index as input. 3. fetch spd over smbus using early smbus functions.
