Instead, boot firmware can use saved training +data to reinitialise the memory controller and memory. + +Unlike native RAM init for other platforms, Haswell does not save the +main structure (the "mighty ctrl" struct) to flash. Instead, separate +structures define the data to be saved, which can be smaller than the +main structure. + +This makes S3 suspend and resume work: RAM contents MUST be preserved +for a S3 resume to succeed, but RAM training destroys RAM contents. + +Change-Id: I06f6cd39ceecdca104fae89159f28e85cf7ff4e6 +Signed-off-by: Angel Pons <th3fanbus@gmail.com> +--- + .../intel/haswell/native_raminit/Makefile.mk | 1 + + .../haswell/native_raminit/activate_mc.c | 17 + + .../intel/haswell/native_raminit/ddr3.c | 41 ++ + .../haswell/native_raminit/raminit_main.c | 34 +- + .../haswell/native_raminit/raminit_native.c | 30 +- + .../haswell/native_raminit/raminit_native.h | 18 + + .../haswell/native_raminit/save_restore.c | 387 ++++++++++++++++++ + 7 files changed, 504 insertions(+), 24 deletions(-) + create mode 100644 src/northbridge/intel/haswell/native_raminit/save_restore.c + +diff --git a/src/northbridge/intel/haswell/native_raminit/Makefile.mk b/src/northbridge/intel/haswell/native_raminit/Makefile.mk +index d97da72890..8fdd17c542 100644 +--- a/src/northbridge/intel/haswell/native_raminit/Makefile.mk ++++ b/src/northbridge/intel/haswell/native_raminit/Makefile.mk +@@ -13,6 +13,7 @@ romstage-y += raminit_main.c + romstage-y += raminit_native.c + romstage-y += ranges.c + romstage-y += reut.c ++romstage-y += save_restore.c + romstage-y += setup_wdb.c + romstage-y += spd_bitmunching.c + romstage-y += testing_io.c +diff --git a/src/northbridge/intel/haswell/native_raminit/activate_mc.c b/src/northbridge/intel/haswell/native_raminit/activate_mc.c +index 78a7ad27ef..0b3eb917da 100644 +--- a/src/northbridge/intel/haswell/native_raminit/activate_mc.c ++++ b/src/northbridge/intel/haswell/native_raminit/activate_mc.c +@@ -333,6 +333,23 @@ enum raminit_status activate_mc(struct sysinfo *ctrl) + return RAMINIT_STATUS_SUCCESS;
