+ * This is a quirk for the Ricoh MMC controller found as a part of
+ * some mulifunction chips.
+
+ * This is very similiar and based on the ricoh_mmc driver written by
+ * Philip Langdale. Thank you for these magic sequences.
+ *
+ * These chips implement the four main memory card controllers (SD, MMC, MS, xD)
+ * and one or both of cardbus or firewire.
+ *
+ * It happens that they implement SD and MMC
+ * support as separate controllers (and PCI functions). The linux SDHCI
+ * driver supports MMC cards but the chip detects MMC cards in hardware
+ * and directs them to the MMC controller - so the SDHCI driver never sees
+ * them.
+ *
+ * To get around this, we must disable the useless MMC controller.
+ * At that point, the SDHCI controller will start seeing them
+ * It seems to be the case that the relevant PCI registers to deactivate the
+ * MMC controller live on PCI function 0, which might be the cardbus controller
+ * or the firewire controller, depending on the particular chip in question
+ *
+ * This has to be done early, because as soon as we disable the MMC controller
+ * other pci functions shift up one level, e.g. function #2 becomes function
+ * #1, and this will confuse the pci core.
