It was pointed out to me that this is the convention for documenting upgrade
instructions, rather than just leaving the instructions in the commit message.
It's possible these commands won't be used again before we transition to git,
but then at least they'll give a path forward for whoever touches this next.

We use these to compile libefivar. The particular motivation for this update is
the inclusion of the RISC-V machine definitions that allow us to build the
library on the platform. This support could easily have been submitted as a
small local diff, but the timing of the release coincided with this work, and
it has been over 3 years since these sources were initially imported.
Note that this comes with a license change from regular BSD 2-clause to the
BSD+Patent license. This has been approved by core@ for this particular
project [1].
As with the original import, we retain only the subset of headers that we
actually need to build libefivar. I adapted imp@'s process slightly for this
update:
# Generate list of the headers needed to build
cp -r ../vendor/edk2/dist/MdePkg/Include sys/contrib/edk2
cd lib/libefivar
make
pushd `make -V .OBJDIR`
cat .depend*.o | grep sys/contrib | cut -d' ' -f 3 |
sort -u | sed -e 's=/full/path/sys/contrib/edk2/==' > /tmp/xxx
popd
# Merge the needed files
cd ../../sys/contrib/edk2
svn revert -R .
for i in `cat /tmp/xxx`; do
svn merge -c VendorRevision svn+ssh://repo.freebsd.org/base/vendor/edk2/dist/MdePkg/$i $i
done
svn merge -c VendorRevision svn+ssh://repo.freebsd.org/base/vendor/edk2/dist/MdePkg/MdePkg.dec MdePkg.dec
[1] https://www.freebsd.org/internal/software-license.html
from the .depend files after the build:
cp -r ../vendor/edk2/MdePkg/Include sys/contrib/edk2
cd lib/libefivar
make
pushd `make -V .OBJDIR`
cat .depend*.o | grep sys/contrib | cut -d' ' -f 3 |
sort -u | sed -e 's=/full/path/sys/contrib/edk2/==' > /tmp/xxx
popd
cd ../../sys/contrib/edk2
rm -rf Include
for i in `cat /tmp/xxx`; do
svn cp svn+ssh://repo.freebsd.org/base/vendor/edk2/dist/MdePkg/$i $i
done
svn cp svn+ssh://repo.freebsd.org/base/vendor/edk2/dist/MdePkg/MdePkg.dec .
The original EDK2 repo is ~265MB, the MdePkg is ~23MB, all
MdePkg/Includes is ~7MB and this minimal set is ~1.3MB.
