It has turned out that it's not a good idea to try to power cycle and to re-initialize the SDIO card, as currently done through mmc_hw_reset(). This because there may be multiple SDIO funcs attached to the same SDIO card and some of the others that didn't execute the call to mmc_hw_reset(), may then simply experience an undefined behaviour. The following two patches in this series attempts to address this problem, by reworking the mmc_hw_reset() behaviour for SDIO. Note that, the code has only compile tested, so any test on HW is greatly appreciated.
