-/*
- * The IXP2400 B0 silicon contains an erratum (#66) that causes writes
- * to on-chip I/O register to not complete fully. What this means is
- * that if you have a write to on-chip I/O followed by a back-to-back
- * read or write, the first write will happen twice. OR...if it's
- * not a back-to-back transaction, the read or write will generate
- * incorrect data.
- *
- * The official work around for this is to set the on-chip I/O regions
- * as XCB=101 and then force a read-back from the register.
