Confirmed that the system sees the full 512 MB, unlike with Parallella's
default boot files.

I've reverted to Parallella's default boot files for now.

Here's a new idea: what about patching one of our HDMI-less bitstreams
into Parallella's BOOT.BIN, with dd?  I can do that easily.  (Just like
I've been extracting bitstreams.)  Then I can retain the old u-boot and
Linux kernel.  Sylvain, if I try this, would I need to take your
devicetree.dtb?

Sylvain, by the way it appears that your u-boot build lacks support for
zImage (zboot command, I think), right?  So I can't use it to load the
original kernel (zImage format) directly, without having figured out and
run a mkimage command first.
