keep as we need to remove the #ifdef AT91 to cpu_is

I've patch for this

Is this for the user IO register where the value written is conditional 
on both RMII/MII and arch type?

yes for 

#if defined(CONFIG_ARCH_AT91)
		macb_writel(bp, USRIO, (MACB_BIT(RMII) | MACB_BIT(CLKEN)));
#else
		macb_writel(bp, USRIO, 0);
#endif
	else
#if defined(CONFIG_ARCH_AT91)
		macb_writel(bp, USRIO, MACB_BIT(CLKEN));
#else
		macb_writel(bp, USRIO, MACB_BIT(MII));
#endif

Ok, but what about non-AT91/AVR32 systems?  They may not have a 
mach/cpu.h and won't have cpu_is_foo() for the platforms the driver is 
interested in.

Could we supply these values in the platform data so the driver doesn't 
need to do any cpu_is_ magic?

for other arch you can but at91 I prefer to avoid this copy and paste in every
soc
