Thanks for your review, Andrew.

Which reminds me - I had submitted two patches as cleanup for the 
xsurf100.c driver that would allow us to drop including lib8390.c there. 
The patches were reviewed by Geert but never picked up by Dave.

The card-specific block_output function provided by the xsurf100.c 
driver needs to execute reset_8380() when transfers get stuffed up. 
According to the comment at the head of lib8390.c, a reset must always 
be followed by a call to __NS8390_init(), so this function is also 
needed by our block_output. The current xsurf100.c includes lib8390.c 
just for the benefit of that single function.

My solution was to export ax_8390_init() through a public wrapper, but 
that didn't find favour, apparently. The only other solution I can see 
would be to add an init_8380 function pointer to the ei_device struct, 
but as init_8390 isn't really board specific, that would be abusing 
ei_device a little, no?

Any feedback welcome.

Cheers,

	Michael
