Announce and release GNU Boot 0.1 RC2 and project status.
The file adding the news is named gnuboot-december-2023.md instead of
gnuboot-0.1-rc1.md as the later is understood as a translation in the
'1-rc1' lang. Renaming the file to gnuboot-0.1-rc1.en.md instead makes
untitled detect the lang correctly but then it assumes this is a
translation and adds a broken link for "English" on the new page.

For now the older Libreboot news were kept as this shows the history
of the project and since GNU Boot is a continuation of the Libreboot
project it makes sense to also keep them.

The CSS also needed to be separated from the template because
otherwise the generated news page would be incomplete and miss all
what comes before the CSS like '<!DOCTYPE html>' for instance.

Finally x-reviewed was changed into x-unreviewed because we can't set
x-reviewed for the news, so the only way to remove the banner for the
individual news is to default to reviewed (and to mark all unreviewed
files as such).

As for the Untitled patch it is needed to make the news page work.

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.
