Patch from Lennert Buytenhek The current __ixp23xx_arch_is_coherent() check assumes that the lower byte of IXP23XX_PRODUCT_ID is identical to the lower byte of processor_id, but this is not the case, and because of this we were incorrectly enabling coherency on A1 stepping CPUs. Stepping A1 of the ixp2350, which has a PRODUCT_ID of 0x401, has '02' in the lower byte of processor_id, while A2, with a PRODUCT_ID of 0x402, has '04' in the lower byte of processor_id. So, to check for >= A2, we really need to check the lower byte of processor_id against >= 4.
