It is commonly used in memory - circuits, such as dynamic random access memory (DRAM), to read and - amplify the weak signals stored in memory cells. - -In this case, we're calibrating the sense amplifiers in the memory -controller. This training procedure uses a magic "sense amp offset -cancel" mode of the DDRIO to observe the sampled logic levels, and -sweeps Vref to find the low-high transition for each bit lane. The -procedure consists of two stages: the first stage centers per-byte -Vref (to ensure per-bit Vref offsets are as small as possible) and -the second stage centers per-bit Vref. - -Because this procedure uses the "sense amp offset cancel" mode, it -does not rely on DRAM being trained. It is assumed that the memory -controller simply makes sense amp output levels observable via the -`DDR_DATA_TRAIN_FEEDBACK` register and that the memory bus is idle -during this training step (so the lane voltage is Vdd / 2). - -Note: This procedure will need to be adapted for Broadwell because -it has per-rank per-bit RxVref registers, whereas Haswell only has -a single per-bit RxVref register for all ranks. - -Change-Id: Ia07db68763f90e9701c8a376e01279ada8dbbe07 -Signed-off-by: Angel Pons <th3fanbus@gmail.com> ---- - .../intel/haswell/native_raminit/Makefile.mk | 1 + - .../haswell/native_raminit/raminit_main.c | 1 + - .../haswell/native_raminit/raminit_native.h | 12 + - .../native_raminit/train_sense_amp_offset.c | 341 ++++++++++++++++++ - .../intel/haswell/registers/mchbar.h | 2 + - 5 files changed, 357 insertions(+) - create mode 100644 src/northbridge/intel/haswell/native_raminit/train_sense_amp_offset.c - -diff --git a/src/northbridge/intel/haswell/native_raminit/Makefile.mk b/src/northbridge/intel/haswell/native_raminit/Makefile.mk -index 8fdd17c542..4bd668a2d6 100644 ---- a/src/northbridge/intel/haswell/native_raminit/Makefile.mk -+++ b/src/northbridge/intel/haswell/native_raminit/Makefile.mk -@@ -21,3 +21,4 @@ romstage-y += timings_refresh.c - romstage-y += train_jedec_write_leveling.c - romstage-y += train_read_mpr.c - romstage-y += train_receive_enable.c -+romstage-y += train_sense_amp_offset.c -diff --git a/src/northbridge/intel/haswell/native_raminit/raminit_main.c b/src/northbridge/intel/haswell/native_raminit/raminit_main.c -index 056dde1adc..ce637e2d03 100644 ---- a/src/northbridge/intel/haswell/native_raminit/raminit_main.c -+++ b/src/northbridge/intel/haswell/native_raminit/raminit_main.c -@@ -60,6 +60,7 @@ static const struct task_entry cold_boot[] = { - { configure_memory_map, true, "MEMMAP", }, - { do_jedec_init, true, "JEDECINIT", }, - { pre_training, true, "PRETRAIN", }, -+ { train_sense_amp_offset, true, "SOT", }, - { train_receive_enable, true, "RCVET", }, - { train_read_mpr, true, "RDMPRT", }, - { train_jedec_write_leveling, true, "JWRL", }, -diff --git a/src/northbridge/intel/haswell/native_raminit/raminit_native.h b/src/northbridge/intel/haswell/native_raminit/raminit_native.h -index 0750904aec..95ccd0a8b3 100644 ---- a/src/northbridge/intel/haswell/native_raminit/raminit_native.h -+++ b/src/northbridge/intel/haswell/native_raminit/raminit_native.h -@@ -22,6 +22,8 @@ - #define NUM_LANES 9 - #define NUM_LANES_NO_ECC 8 - -+#define NUM_BITS 8 -+ - #define COMP_INT 10 - - /* Always use 12 legs for emphasis (not trained) */ -@@ -218,6 +220,7 @@ enum raminit_status { - RAMINIT_STATUS_MPLL_INIT_FAILURE, - RAMINIT_STATUS_POLL_TIMEOUT, - RAMINIT_STATUS_REUT_ERROR, -+ RAMINIT_STATUS_SAMP_OFFSET_FAILURE, - RAMINIT_STATUS_RCVEN_FAILURE, - RAMINIT_STATUS_RMPR_FAILURE, - RAMINIT_STATUS_JWRL_FAILURE, -@@ -243,6 +246,12 @@ struct raminit_dimm_info { - bool valid;
