-Subject: [PATCH 1/6] Revert "Revert "nb/amd/mct_ddr3: Fix RDIMM training
- failure on Fam15h" (fixes a bug that prevent certain RAM modules from
- booting)
-
-This reverts commit 610d1c67b2298a9840681c2b4492b6d3fdf44a46.
-
-After 610d1c67b2298a9840681c2b4492b6d3fdf44a46 many RAM modules wouldn't work and you couldn't even see any output on the screen.

-Subject: [PATCH 3/6] Tweak cmos defaults for KCMA-D8 (for a little speed
- boost)
-
-63xx CPUs have the option to use a reduced latency value inside the crossbar.
-Setting "experimental_memory_speed_boost=Enable" aparently only has an effect
-on 63xx CPUs and may, in certain cases, yield a slight memory bandwidth
-increase (according to Timothy Pearson), but maybe it also works for
-43xx CPUs.
-
-Setting "l3_cache_partitioning=Enable" will increase performance in certain
-situations. See:
-https://developer.arm.com/documentation/100453/0401/functional-description/l3-cache/l3-cache-partitioning?lang=en

-
-This really only benefits 63xx opterons which are less reliable in libreboot due
-to lack of CPU microcode updates, but we might aswell enable this anyway.

-
-the original upstream died
-
-i decided to host it myself, on libreboot rsync,
-for use by mirrors.
-
-this is also useful for GNU Boot, when downloading
-acpica on coreboot 4.11_branch, for fam15h boards
-
-this change is not necessary on other coreboot trees,
-which adhere to new coreboot policy (newer coreboot
-pulls acpica from github, which is fairly reliable)

-++      --  Saved_Cleanup when its handler completes.
-++      --
-++      --  This ownership transfer mechanism ensures safety, as in
-++      --  single release and no dangling pointers, because there is no
-++      --  way to hold on to the Machine_Occurrence of an

-++      --  have the following possibilities:

-++      --  - Reraise_Occurrence is handled within the running handler,
-++      --  and so when completing the dynamically nested handler, we
-++      --  must NOT release the exception.  A Claimed_Cleanup upon

-++      --  enclosing handler, ensures the exception will not be
-++      --  released by the nested handler, but rather by the enclosing
-++      --  handler.
-++      --
-++      --  - Reraise_Occurrence/reraise escapes the running handler,
-++      --  and we run as an exceptional cleanup for GCC_Exception.  The
-++      --  Saved_Cleanup was reinstalled, but since we're propagating
-++      --  the same machine occurrence, we do not release it.  Instead,
-++      --  we transfer responsibility for releasing it to the eventual
-++      --  handler of the propagating exception.
-++      --
-++      --  - An unrelated exception propagates through the running
-++      --  handler.  We restored GCC_Exception.Saved_Cleanup above.
-++      --  Since we're propagating a different exception, we proceed to
-++      --  release GCC_Exception, unless Saved_Cleanup was
-++      --  Claimed_Cleanup, because then we know we're not in the
-++      --  outermost handler for GCC_Exception.
-++      --
-++      --  - The handler completes normally, so it reinstalls the
-++      --  Saved_Cleanup and runs it, unless it was Claimed_Cleanup.
-++      --  If Saved_Cleanup is null, Unwind_DeleteException (currently)
