the removed info is a relic, from before all information was
centralised in docs/install/spi.md
remove it, because it is extremely confusing for new readers
Add initial documentation about flashing Libreboot on supported ChromeOS
devices. Link the Chromebooks in the hardware index to it. I only have
tried firmware work on gru-kevin, so there is an implicit focus on that,
but most others should be similar.
The one exception is gru-bob, as it is new enough to support Closed Case
Debugging which can be used to disable write-protect and flash the
firmware externally. Provide links to the ChromiumOS docs for that.
Although not supported on Libreboot, x86 Chromebooks still carry the
curse that is unreadable non-redistributable Intel ME firmware, so
provide a warning against flashing x86 images without it just in case.

At least one Chromebook (gru-kevin) has GD25LQ64C [1], which is a 1.8V
8MB SPI NOR flash chip. Although it can be flashed internally, it has to
be flashed externally when a broken image is flashed. I have been using
an unmodified bad CH341A with a 1.8V adapter which works fine so far.
Try to replace mentions of 3.3V with either nondescript terms like
"power" or "VCC", or both 1.8V and 3.3V, except where it's specifically
about 3.3V. Add warnings to check the part number and datasheet for the
rated supply voltage for the chips, and to make sure to match the
flashing hardware's supply to that.

mistakes made during osbwww->lbmk merge have been corrected
mostly a few search/replace errors, and deleted pages that have since
been restored, or pages that were incorrectly scrubbed are now full; for
example, pages that said there are no releases yet (from osboot) have
been replaced with the version from libreboot that links to release archives,
which *do* exist in libreboot
i generally fixed all other minor issues with paragraphs that i found, where
the paragraphs made sense in osboot.org but did not so on libreboot.org
this is all of my fixes, after auditing the recent merge. no point splitting
them up. just patch it up and go!
this is imported from osbwww, based on a change shmalebx9 made.
this patch is a rebase/cherry-pick from osbwww performed by leah rowe,
based off of shmalebx9's work
