note: me6_update_parser needs to be written, similar
to me7_update_parser, to generate the partition
tables within intel me6 on lenovo bios updates.

the current logic in lbmk goes like this:
mkdir -p vendorfiles/cache/

and save your factory dump as:
vendorfiles/cache/x201_factory.rom

the build system has been modified, in such a way
as to support extracting me.bin (which is the full
one) and then neutering from this.

this is done automatically, if the file is present,
but you must first insert that file there, which means
you'll need a dump of the original boot flash on your
thinkpad x201

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
