it doesn't really make sense for them to be under
blobs/ - nominally, they are blobs, but they are
well-understood data files containing config data,
that is easily parsed by tools like ich9show or
ifdtool (and tools like bincfg or nvmutil)

blobs/ has been re-purposed: this directory no longer
exists in lbmk, but it is created (and on .gitignore)
when needed, by blobutil

thus, the blobs/ directory shall only contain vendor
files, and only those files that libreboot scrubs from
releases. therefore, build/release/src can (and has
been) simplified; it currently copies just the ifd and
gbe files from blobs/, selectively, and this logic is
quite error prone, requiring maintenance. now, the
build/release/src script simply copies config/ (which
only ever contains distributable files) and entirely
ignores the blobs/ directory

the blob download script already creates the required
directory, except for the sch5545 download; this is
now fixed

lbmk code size is slightly smaller, due to this patch

This cuts down on build time, and it will allow libreboot
to remove large chunks of code.

these ifd/gbe configs are just binary-encoded config files,
in a format well-understood. they can easily be opened up
and displayed, using ich9show or ifdtool, and manipulated
by these tools; bincfg can generate them from scratch, and
nvmutil can change mac addresses, for example.

so, do this and remove from lbmk the following:

* ich9utils (which contains ich9gen) - not needed anymore
* code in lbmk for handling ich9gen and insertions; the
  coreboot build system is now used, for this same purpose,
  so remove such code from lbmk

this results in a massive code size reduction (thousands of
lines) in lbmk; smaller when only looking at the build
system, but much larger when you consider that ich9utils
is also removed (about 3k sloc)

coreboot revision:
d86260a134575b083f35103e1cd5c7c7ad883bce
from 2 August 2023

The patches were updated. HP 8300 USDT has now been merged upstream,
so that patch is no longer included in lbmk.

SD card fix for E6400 merged upstream, so now it's removed in lbmk.
The nvidia E6400 patch (devicetree.cb) has not yet merged upstream.

The ifdtool --nuke option has been rebased.
Patches as follow-ups to earlier patches removed; for example, patches
that set VRAM to 352MB on GM45 have been removed, and replaced with
patches that just set 256MB in the first place (this is more stable).

This was mostly a clean rebase, of all the patches. It went smooth.
I haven't updated cros/haswell yet; the 4.11_branch revision used
on fam15h will also remain, for now.

The coreboot configurations have been updated, for this new
revision of coreboot.

osboot is now part of libreboot, and will soon shut down.
libreboot now conforms to osboot policy.

tianocore is a liability for the libreboot project. it's a bloated mess, and
unreliable, broken on many boards, and basically impossible to audit.

i don't trust tianocore, so i'm removing it.

this is forked from the "libre" branch in osboot, which is itself a libre,
deblobbed fork of osboot, a blobbed up fork of libreboot

libreboot needed to be purged clean. this is the new libreboot development
repository. the old one has been abandoned
