From 90ae08922d7f6fdc8b762cb7bc1e2d8d85807854 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Fri, 12 Mar 2021 17:00:52 +0100 Subject: nb/intel/haswell: Consolidate memory-down SPD handling Mainboards do not need to know about `pei_data` to tell northbridge code where to find the SPD data. Adjust `mb_get_spd_map` to take a pointer to a struct instead of an array, and update all the mainboards accordingly. Currently, the only board with memory-down in the tree is google/slippy. Mainboard code now obtains the SPD index in `mb_get_spd_map` and adjusts the channel population accordingly. Then, northbridge code reads the SPD file and uses the index that was read in `mb_get_spd_map`, and copies it to channel 0 slot 0 unconditionally. MRC only uses the first position of the `spd_data` array, and ignores the other positions. In coreboot code, `setup_sdram_meminfo` uses the data of each SPD index, so `copy_spd` has to account for this. Tested on Asrock B85M Pro4, still boots and still resumes from S3.
