2020-08-06soc/intel/tigerlake: add common routine for DDR initNick Vaccaro
Add a common routine meminit_ddr() that calls the appropriate meminit routine based on whether the memory type requested is LPDDR4x or DDR4. BUG=b:161772961 TEST='emerge-volteer coreboot chromeos-bootimage' and verify that volteer still boots. NOTE that this only tests the lpddr4 side of the implementation. I do not have a DDR4 board to test this on.

2020-04-25soc/intel/tigerlake: Fix FSP SPD index for DDR4Furquan Shaikh
For DDR4, FSP expects channel 0 to set SPD for index 0 and channel 1 to set SPD for index 4. This change adds a helper macro to translate DDR4 channel # to the index # that the FSP expects. BUG=b:154445630 TEST=Verified that memory initialization for DDR4 is successful.

2020-04-02soc/intel/tigerlake: Reorganize memory initialization supportFurquan Shaikh
This change reorganizes memory initialization code for LPDDR4x on TGL to allow sharing of code when adding support for other memory types. In follow-up changes, support for DDR4 will be added. 1. It adds configuration for memory topology which is currently only MEMORY_DOWN, however DDR4 requires more topologies to be supported. 2. spd_info structure is organized to allow mixed topologies as well. 3. DQ/DQS maps are organized to reflect hardware configuration. TEST=Verified that volteer still boots and memory initialization is successful.
