-Subject: [PATCH 02/26] nb/intel/haswell: Introduce option to not use MRC.bin
-
-Introduce the `USE_NATIVE_RAMINIT` Kconfig option, which should allow
-booting coreboot on Haswell mainboards without the need of the closed
-source MRC.bin. For now, this option does not work at all; the needed
-magic will be implemented in subsequent commits. Add a config file to
-make sure the newly-introduced option gets build-tested.

-
-Implement native DMI init for Haswell and Lynx Point. This is only

+Subject: [PATCH 16/20] Haswell NRI: Implement fast boot path
+
+When the memory configuration hasn't changed, there is no need to do
+full memory training. 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.

+Subject: [PATCH 17/20] haswell NRI: Do sense amplifier offset training
+
+Quoting Wikipedia:
+
+ A sense amplifier is a circuit that is used to amplify and detect
+ small signals in electronic systems. 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.

+Subject: [PATCH 18/20] Remove warning for coreboot images built without a
+ payload
I added this in upstream to prevent people from accidentally flashing
roms without a payload resulting in a no boot situation, but in
libreboot lbmk handles the payload and thus this warning always comes
up. This has caused confusion and concern so just patch it out.

+Subject: [PATCH 1/4] nb/intel/haswell: make IOMMU a runtime option
+
+When I tested graphics cards on a coreboot port for Dell
+OptiPlex 9020 SFF, I could not use a graphics card unless
+I set iommu=off on the Linux cmdline.
+
+Coreboot's current behaviour is to check whether the CPU
+has vt-d support and, if it does, initialise the IOMMU.
+
+This patch maintains the current behaviour by default, but
+allows the user to turn *off* the IOMMU, even if vt-d is
+supported by the host CPU.
+
+If iommu=Disable is specified, the check will not be
+performed, and the IOMMU will be left disabled. This option
+has been added to all current Haswell boards, though it is
+recommended to leave the IOMMU turned on in most setups.

+Needed to make graphics cards work. Turning it on is

+by default. The IOMMU is extremely buggy when a graphics

+Subject: [PATCH 1/1] mb/dell/optiplex_9020: Implement late HWM initialization
+
+There are 4 different chassis types specified by vendor firmware, each
+with a slightly different HWM configuration.
+
+The chassis type to use is determined at runtime by reading a set of
+4 PCH GPIOs: 70, 38, 17, and 1.
+
+Additionally vendor firmware also provides an option to run the fans at
+full speed. This is substituted with a coreboot nvram option in this
+implementation.
+
+This was tested to make fan control work on my OptiPlex 7020 SFF.
+
+NOTE: This is superficially similar to the OptiPlex 9010's SCH5545
+however the OptiPlex 9020's SCH5555 does not use externally
+programmed EC firmware.

+Subject: [PATCH 4/4] nb/haswell: Fully disable iGPU when dGPU is used
+
+My earlier patch disabled decode *and* disabled the iGPU itself, but
+a subsequent revision disabled only VGA decode. Upon revisiting, I
+found that, actually, yes, you also need to disable the iGPU entirely.
+
+Tested on Dell 9020 SFF using broadwell MRC, with both iGPU and dGPU.
+With this patch, the iGPU is completely disabled when you install a
+graphics card, but the iGPU is available to use when no graphics card
+is present.
+
+For more context, see:

+
+ nb/haswell: Disable iGPU when dGPU is used
+
+And look at the Gerrit comments:
+
+https://review.coreboot.org/c/coreboot/+/80717/
+
+So, my original submission on change 80717 was actually correct.
+This patch fixes the issue. I tested on iGPU and dGPU, with both
+broadwell and haswell mrc.bin.
