* [U-Boot] [PATCH] net: dm9000x: use standard I/O accessors

The current dm9000x driver accesses its memory mapped registers directly
instead of using the standard I/O accessors.  This can cause problems on
Blackfin systems as the accesses can get out of order.  So convert the
direct volatile dereferences to use the normal in/out macros.

I think the arch/arm/include/asm/io.h needs some rework with the __io
definition. Is it the right way?

Hi,

#define __io

in devkit8000.h fixes the upper part of the error messages.

is still there.
