As there aren't any Andestech SoCs upstream, I am in favour of keeping
in soc/renesas for maintenance. If in future there comes a new soc
from Andestech (which will go into soc/andestech) we will have to
split the maintenance work.
But anyway if there will be any users of L2 cache we could always
provide a config option which can be used by other SoCs.
Said that I'll let Geert decide on this.
Cheers,
Prabhakar
