The driver doesn't care per se, but how the device tree is generated 
differs compared to how it is done in PowerPC, at least for Leon SPARC.

I'll look into it. At the very least the Kconfig entry for 
sja1000_of_platform could not solely depend on PPC_OF, but the more 
important issue is the device tree differences.
