Tell me if a configuration variable that I setup in the macb.h file 
depending on CPU is acceptable ?
Here is the snippet :
in drivers/net/macb.h

+/* MACB IP used by AVR32 & AT91 have two
+ * different layout for USRIO register. */
+#if !defined(CONFIG_AVR32)
+/* Use AT91 USRIO layout */
+#define CONFIG_MACB_USRIO_CFG1 1
+#endif

And then I use CONFIG_MACB_USRIO_CFG1 in macb.c

This will prevent me from setting this variable in every CPU config file...

Bye,
