The build system was designed to produce images with different GPU
drivers for a single computer and/or to show the image name in the
final image names, to enable users to know which GPU driver was used.
However since all boards have practically speaking the same GPU driver
('libgfxinit') this adds too much complexity for almost no benefits.

It is possible to install GNU Boot on I945 Thinkpads without opening
the computer even if the nonfree bios sets the bootblock region (the
last 64K of the flash chip) read-only.
The flash chip looks like that:
+----- -----+---------------------------+-------------------------+
| ... | Secondary bootblock (64k) | Primary bootblock (64k) |
+----- -----+---------------------------+-------------------------+
0 0x1e0000 2MiB
To bypass the read-only restriction we use an utility (bucts) that
tells the hardware to swap the primary bootblock with the secondary
one for the next boot. We then have to disable that swap and reflash
again.
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK generates the two bootblocks
directly in coreboot so we don't need to use special commands to do
that anymore.
In addition the MacBook 1.1 and 2.1 are known not to have such
read-only restrictions so they don't need to have
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK enabled.

In coreboot this build option is used to download nonfree software so
they can be included later on in the builds.
It doesn't necessarily means that nonfree software ends up in the
images but it is way easier and safer to disable that than having to
audit precisely what happen for each computer and build configuration.

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.
