We should probably do another fix-capitalization pass on docs/,
because a bunch more "ARM" uses have crept in since 6fe6d6c9a95.
(6fe6d6c9a95's commit message says that architecture names like
"ARMv8" retain all-caps, but I think that was my personal taste
creeping in -- at any rate the current Arm ARM uses "Armv8",
"Armv9", etc. It was right that "ARM926" etc should stay all-caps,
though.)
