[PATCH] ARM: cns3xxx: Add support for L2 Cache Controller

[Tommy Lin]

Yes, CNS3xxx is V6K. I just submit another patch before I saw this mail.
CNS3xxx is ARM11 MPCore (dual core). It selects the ARM 11 (V6) in the
beginning of
project. So it is better to correct the CPU type to V6K.

Best regards,
Tommy Lin
