+/*
+ * The design of the Diva management card in rp34x0 machines (rp3410, rp3440)
+ * seems rushed, so that many built-in components simply don't work.
+ * The following quirks disable the serial AUX port and the built-in ATI RV100
+ * Radeon 7000 graphics card which both don't have any external connectors and
+ * thus are useless, and even worse, e.g. the AUX port occupies ttyS0 and as
+ * such makes those machines the only PARISC machines on which we can't use
+ * ttyS0 as boot console.
