-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.

-Subject: [PATCH 05/26] sb/intel/lynxpoint: Add native USB init
-
-Implement native USB initialisation for Lynx Point. This is only needed
-when MRC.bin is not used.
-
-TO DO: Figure out how to deal with the FIXME's and TODO's lying around.

-Subject: [PATCH 12/26] haswell NRI: Post-process selected timings
-
-Once the MPLL has been initialised, convert the timings from the SPD to
-be in DCLKs, which is what the hardware expects. In addition, calculate
-the values for tREFI and tXP.

-Subject: [PATCH 15/26] haswell NRI: Program memory map
-
-This is very similar to Sandy/Ivy Bridge, except that there's several
-registers to program in GDXCBAR. One of these GDXCBAR registers has a
-lock bit that must be set in order for the memory controller to allow
-normal access to DRAM. And it took me four months to realize this one
-bit was the only reason why native raminit did not work.

-Subject: [PATCH 17/26] haswell NRI: Add pre-training steps
-
-Implement pre-training steps, which consist of enabling ECC I/O and
-filling the WDB (Write Data Buffer, stores test patterns) through a
-magic LDAT port.

-Subject: [PATCH 22/26] haswell NRI: Add function to change margins
-
-Implement a function to change margin parameters. Haswell provides a
-register to apply an offset to margin parameters during training, so
-make use of it. There are other margin parameters that have not been
-implemented yet, as they are not needed for now and special handling
-is needed to provide offset training functionality.

-Subject: [PATCH 24/26] haswell NRI: Add write leveling
-
-Implement JEDEC write leveling, which is done in two steps. The first
-step uses the JEDEC procedure to do "fine" write leveling, i.e. align
-the DQS phase to the clock signal. The second step performs a regular
-read-write test to correct "coarse" cycle errors.

-Subject: [PATCH 25/26] haswell NRI: Add final raminit steps
-
-Implement the remaining raminit steps. Although many training steps are
-missing, this is enough to boot on the Asrock B85M Pro4.

-Subject: [PATCH] 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.
