[PATCH 2/6] mmc: move mmc_wait_busy() to core

Currently this function is used inside the mmc test driver. But it is also usable in the (upcoming) firmware update patch. So move this function out of mmc_test.c into core.c. Signed-off-by: Holger Schurig --- drivers/mmc/card/mmc_test.c | 46

[RFC 0/6] mmc: Field Firmware Update

There have been some attempts to add FFU (field firmware update). The last AFAIK in Nov 2014, http://www.spinics.net/lists/linux-mmc/msg29324.html But it seems that the committers weren't persistent enought. I took the liberty to take Avi's patch and make it hopefully maintainer-review
