- * This is a conceptually ridiculous driver, but it is required by the way
- * the Ricoh multi-function chips (R5CXXX) work. 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. As a bonus,
- * a detection event occurs immediately, even if the MMC card is already
- * in the reader.
- *
- * 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. As
- * such, it makes what this driver has to do unavoidably ugly. Such is life.
