Merge website and website-build.
Before being merged with the commit
dc6e1f32c1 ("Import website-build to
build the GNU Boot website."), website-build was a separate git
repository.

And so, even after the merge, until the commit
20d122e94a ("website-build: use website
from local git repository."), it still worked in the same way and
still downloaded the website from git.

This prevented merging the website and website-build directories
together as the GNU Boot repository also needed to be a valid Untitled
website repository as well.

Now after this commit, the website is built from the same git tree, so
we can simply adjust the build scripts to be able to move things
around.

In addition of making things more clear for contributors, it also
simplify the migration to haunt as with haunt we typically have the
haunt.cfg (and the autotools build code if needed) code in the top
directory and the markdown files in a subdirectory.

title: ThinkPad R500 x-unreviewed: true ...

This board as basically identical to the T500, and has very similar disassembly. You must take it apart and flash the chip externally.

The chip is 4MiB NOR flash (SPI protocol) is SOIC8 form factory.

Refer to the following guide:
Externally rewrite 25xx NOR flash via SPI protocol

Unlike other GM45+ICH9M thinkpads in Libreboot, the R500 doesn't have an Intel PHY (for Gigabit Ethernet). However, Libreboot still includes an Intel flash descriptor, but with just the descriptor and BIOS region. The ich9gen program supports this fully.

Therefore, you do not have to worry about the MAC address. The onboard NIC for ethernet is made by Broadcom (and works in linux-libre).

Refer to T500 disassembly guide. The R500 disassembly procedure is almost identical.
