Leah Rowe 87993b88a8 remove bbb-specific info on external flash guides
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

Alper Nebi Yasak 2f712e36fb install/spi: Generalize to not assume 3.3V
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.

Leah Rowe 6e2c3f0234 post-merge bonerfixes
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!
