 /*
- * 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.
+ * On the IXP2400, we can't use XCB=000 due to chip bugs.  We use
+ * XCB=101 instead, but that makes all I/O accesses bufferable.  This
+ * is not a problem in general, but we do have to be slightly more
+ * careful because I/O writes are no longer automatically flushed out
+ * of the write buffer.
  *
+ * In cases where we want to make sure that a write has been flushed
+ * out of the write buffer before we proceed, for example when masking
+ * a device interrupt before re-enabling IRQs in CPSR, we can use this
+ * function, ixp2000_reg_wrb, which performs a write, a readback, and
+ * issues a dummy instruction dependent on the value of the readback
+ * (mov rX, rX) to make sure that the readback has completed before we
+ * continue.
