mb/intel/tglrvp: add Tiger Lake memory initialization support
Update memory parameters based on memory type supported by Tiger lake RVP 1. Update dq/dqs mappings 2. Update spd data for Tiger lake LPDDR4 SAMSUNG/MICRON memory 3. Add SPD data bin files for supported memory types 4. Update other FSPM UPDs as part of memory initialization BUG=none BRANCH=none TEST= build tglrvp flash and boot to kernel Signed-off-by: Srinidhi N Kaushik <srinidhi.n.kaushik@intel.com> Change-Id: I7248862efd1dcd5a0df0e17d39b44c168caa200e Reviewed-on: https://review.coreboot.org/c/coreboot/+/38998 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Wonkyu Kim <wonkyu.kim@intel.com> Reviewed-by: Nick Vaccaro <nvaccaro@google.com> Reviewed-by: Subrata Banik <subrata.banik@intel.com>
