Subject: [PATCH] Revert "Remove the unused sh4eb target"
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This reverts commit 73ceb12960e686b763415f0880cc5171ccce01cf.

The "r2d" machine can work in big endian mode, see:

 https://lore.kernel.org/qemu-devel/d6755445-1060-48a8-82b6-2f392c21f9b9@landley.net/

So the reasoning for removing sh4eb was wrong.
