An MMC/SD/SDIO stack using CAM Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's flexible queueing will make it easier to write non-storage drivers than the legacy stack. SDIO drivers from both the kernel and as userland daemons are possible, though much of that functionality will come later. Some of the CAM integration isn't complete (there are sleeps in the device probe state machine, for example), but those minor issues can be improved in-tree more easily than out of tree and shouldn't gate progress on other fronts. Appologies to reviews if specific items have been overlooked. Submitted by: Ilya Bakulin Reviewed by: emaste, imp, mav, adrian, ian Differential Review: https://reviews.freebsd.org/D4761 merge with first commit, various compile hacks.

# MMCCAM is the kernel config for doing MMC on CAM development
# and testing on bhyve
# $FreeBSD$
include MINIMAL
Add MMCCAM-enabled kernel config for IMX6, reduce debug noice in MMCCAM kernels CAM_DEBUG_TRACE results in way too much debug output than needed now. When debugging, it's always possible to turn on trace level using camcontrol. Approved by: imp (mentor) Differential Revision: https://reviews.freebsd.org/D12110
