The problem is that you have not registered a platform device - that
is the kernel doesn't know you have a xilinx_fb device in the system,
so it never calls the _probe() function.

To do this, look in arch/microblaze/platform/common - you need to
create a file called xilinxfb.c here.  Link it in to the Makefile of
this directory.

This code must create a platform_device structure, and then call
platform_device_register() on that object.

There are other examples in this same directory for other devices -
e.g. xilinx_spi.c.  The pattern should be clear.

Regards,

John
