coreboot/dell: move e6400 to new tree, dell

the ddr2 fix broke *ddr3* on gm45 thinkpads in
testing, depending on memory modules. this was
established by removing patches, re-doing
configs etc, on a user's X200 (testing gentoo
and freebsd). the X200 kept randomly rebooting
or having random glitches.

the configs themselves (gm45 thinkpads) will
also be re-done, because i found minor issues
unrelated, but this patch moves dell e6400 to
its own tree. the ddr2 fix is no longer present
in coreboot/default, only coreboot/dell.

i noticed minor differences in gm45 thinkpad
configs, when re-doing the configs, versus
what are currently in lbmk master; for instance,
vbt was not enabled anymore, on thinkpad x200.
modifications to these will be done separately.

+Subject: [PATCH 15/22] util/ifdtool: add --nuke flag (all 0xFF on region)
+
+When this option is used, the region's contents are overwritten
+with all ones (0xFF).
+
+Example:
+
+./ifdtool --nuke gbe coreboot.rom
+./ifdtool --nuke bios coreboot.com
+./ifdtool --nuke me coreboot.com
+
+Rebased since the last revision update in lbmk.

+
+This reverts commit 70fea013c7ebd6d85a7806748233fcfd76802f5f.
+
+Enabling PECI without microcode updates loaded causes the CPUID feature set
+to become corrupted. And one consequence is broken SpeedStep. At least, that's
+my understanding looking at Intel Errata. This revert is not a fix, because
+upstream is correct (upstream assumes microcode updates). We will simply
+maintain this revert patch in Libreboot, from now on.

+Subject: [PATCH 17/22] GM45-type CPUs: don't enable alternative SMRR
+
+This reverts the changes in coreboot revision:
+df7aecd92643d207feaf7fd840f8835097346644
+
+While this fix is *technically correct*, the one in
+coreboot, it breaks rebooting as tested on several
+GM45 ThinkPads e.g. X200, T400, when microcode
+updates are not applied.
+
+Since November 2022, Libreboot includes microcode
+updates by default, but it tells users how to remove
+it from the ROM (with cbfstool) if they wish.
+
+Well, with Libreboot 20221214, 20230319 and 20230413,
+mitigations present in Libreboot 20220710 (which did
+not have microcode updates) do not exist.
+
+This patch, along with the other patch to remove PECI
+support (which breaks speedstep when microcode updates
+are not applied) have now been re-added to Libreboot.
+
+It is still best to use microcode updates by default.
+These patches in coreboot are not critically urgent,
+and you can use the machines with or without them,
+regardless of ucode.
+
+I'll probably re-write this and the other patch at
+some point, applying the change conditionally upon
+whether or not microcode is applied.
+
+Pragmatism is a good thing. I recommend it.

+Subject: [PATCH 19/22] 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 1/1] don't use github for the acpica download
+
+i have the tarball from a previous download, and i placed
+it on libreboot rsync, which then got mirrored to princeton.
+
+today, github's ssl cert was b0rking the hell out and i really
+really wanted to finish a build, and didn't want to wait for
+github to fix their httpd.
+
+so i'm now hosting this specific acpica tarball on rsync.
+
+this patch makes that URL be used, instead of the github one.
+
+that's the 2nd time i've had to patch coreboot's acpica download!

+Subject: [PATCH 1/1] Revert "Kconfig: Bring HEAP_SIZE to a common, large
+ value"
+
+This reverts commit 44a48ce7a46c36df69f7b2cf3552bf10fa5f61b6.
+
+NOTE:
+
+this is done instead of merging:
+https://review.coreboot.org/c/coreboot/+/78623
+
+which is still under review for now
+
+the patch i'm reverting is this one:
+https://review.coreboot.org/c/coreboot/+/78270
+
+this was actually only merged the day before i
+updated coreboot revs in lbmk to the 12 october rev,
+so there's no harm in quickly reverting this for now
+
+however, later on, we will rely on the other patch
