I don't have any strong preference for those notations,
but I simply followed the existing format used in doc/kwboot.1
and doc/mkimage.1 which are the only two instances of
man pages in the U-Boot source.

So I'd like to see guidelines/rules for U-Boot first.

I can find a use of "\fB" (and others) also in your reference:

I don't know, but will drop the decoration here.

ditto
I see AUTHORS sections in doc/kwboot.1 and doc/mkimage.1.

For instance, no reference to "HOMEPAGE" in "man man-pages"
but doc/mkimage.1 has one.
