Hi all
I'm not sure if anyone else has found it to be a problem but some boards we recently had built have an IXP425 on them which reports a Product Revision value 0x2 (lowest four bits of CP15, reg 0). This is only a problem because the file
cpu/ixp/npe/npe.c
uses this field in the npe_initialize function to decide how to determine how many ethernet ports there are. Unfortunately the case statement only accounts for revision values 0x0 (IX_FEATURE_CTRL_SILICON_TYPE_A0) and 0x01 (IX_FEATURE_CTRL_SILICON_TYPE_B0) so that the existing code doesn't think that these processors have any ethernet ports available. I found that by adding a 'default:' statement before line #639 remedied the problem. This file is part of u-boot, not the Intel npe library.
Since it seems that someone is immanently about to release a patch on the npe stuff anyway, would it be too much trouble to add the 'default:' statement or otherwise handle this product revision?
Thanks
