IMO, there is _not_ much demand for big endian. I mean, while it
makes sense to let dpkg (or other tools) sh3eb, sh4eb enabled, I don't
think there is actual users for big endian system. The evaluation
boards has setting of endian-ness, that's true, but I don't know any
real products with big endian. HP, SEGA, Hitachi, and Compaq, all
products are little endian.
Here's a additional explanation.
SuperH series (SH in short) started with SH-1 series. For SH-1 and
SH-2, its major usage was big endian.
SH-3 came, its customer is Microsoft (WindowsCE). SH-4 came, its
customer is SEGA (Dreamcast). From SH-3 and SH-4, little endian is
majority. Actually, some feature is only available with little endian
setting (such as PCMCIA bus support).
So, some people who migrated from SH-1/SH-2 may stick big endian but
it's rare case.
Err... however, it seems for me that FPU of SH-4 is designed for big
