[<fh...@at...>]

I'm going to try the 53c770 driver as memory mapped, when I 
compile it that way and try to insert the module I get 
undefined symbols readw_l2b, writew_b2l, writel_b2l, and
readl_l2b.  Does anyone know what these are?  I've assumed
that b2l means "big to little" etc.  I'm not totally sure I should get
those errors though because I believe the Power PC and 53c770 are both big
endian.

While grep'ing for readw_l2b, I saw that you have to add your own definitions
to sym53c8xx_defs.h. It seems like sym53c8xx_defs.h contains support for PIO
on PPC only, not for MMIO.

Depending on the wanted endiannes (I don't know how the 53c770 is connected to
the PPC bus, it could be byte swapped), you should map e.g. writel_b2l() to
out_be32() or out_le32(). Note that arguments for writel and out_*32 are in a
different order.

Good luck!

How would I find out?  I tried sending a message to Ralph Schmidt but so
far I have received no answer.  Attached is my latest dmesg after
compiling the driver as MMIO.  I guess I now have to learn about SCSI
scripts.  Any pointers?
