Fix setting RCA for MMC cards

2018-06-19T20:02:03+00:00

Unlike SD cards, that publish RCA in response to CMD3,
MMC cards expect the host to set RCA itself.

Since we don't support multiple MMC cards on the bus,
just assign a static RCA of 2 to the attached MMC card.

Miscellaneous fixes and improvements to MMCCAM stack

2017-09-15T19:47:44+00:00

 * Demote the level of several debug messages to CAM_DEBUG_TRACE
 * Add detection for SDHC cards that can do 1.8V. No voltage switch sequence
   is issued yet;
 * Don't create a separate LUN for each SDIO function. We need just one to make
   pass(4) attach;
 * Remove obsolete mmc_sdio* files. SDIO functionality will be moved into the
   separate device that will manage a new sdio(4) bus;
 * Terminate probing if got no reply to CMD0;
 * Make bcm2835 SDHCI host controller driver compile with 'option MMCCAM'.

An MMC/SD/SDIO stack using CAM

2017-07-09T16:57:24+00:00

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.
