this is of course a two-sided problem: providing all DTBs might
include systems on which d-i does really not work due to lack of
(enabled) drivers in the armmp kernel, but on the other hand
providing only the "known-supported" DTBs limits the use of d-i to
currently only two devices for armhf (IMX53QSB and vExpress) while it
surely works on a lot more systems for which we just lack the
specific confirmation. Doing so would probably limit the userbase
a lot more than necessary.
The only issue in d-i/flash-kernel for "unknown" systems appears to
be the "making the system bootable" step; otherwise d-i does not seem
to need device-specific information to do it's work. I have
described this limitation in the installation-guide
(http://d-i.debian.org/manual/en.armhf/ch02s01.html, section 220.127.116.11.
"Platforms supported by Debian/armhf") and think the advantages of
providing all DTBs overall outweigh the disadvantages, as long as the
limitations are documented.
