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!
