[PATCH 0/3] ld: Orphan section placement tweaks

[Andrew Burgess <andrew dot burgess at embecosm dot com>]

This series is primarily intended to address two edge cases relating
to the placement of orphan sections where I think the current linker
behaviour is non-obvious.  Both cases relate to how LMAs are assigned
to orphan sections.

The first patch is a small documentation extension to make crystal
clear somethng which I don't think is spelled out clearly enough in
the manual right now.

I have run this series against a wide range of targets for testing,
with no regressions.  I did however, block the new tests from running
on a moderately sized sub-set of targets; the new tests make use of
rather restrictive linker scripts, the blocked targets all failed to
link or pass due to additional target-specific sections messing up the
results, or the target not being happy with the memory regions in the
test.  I figure that the large number of targets the tests do run on
should be enough - let me know if this is a problem.

Thanks,
Andrew
