Since many have the system root on MMC/SD we must allow some foot
shooting when it comes to resume.
We cannot detect if a card is removed and reinserted during suspend,
so the safe approach would be to assume it was, avoiding potential
filesystem corruption. This will of course not work if you cannot
release the card before suspend.
This commit adds a compile time option that makes the MMC layer
assume the card wasn't touched if it is redetected upon resume.

mmc: add bus handler2007-05-01T11:41:06ZPierre Ossman2006-12-30T23:11:32Zurn:sha1:7ea239d9e6d6993469a6a8ca83ff23834dfc3fce
Delegate protocol handling to "bus handlers". This allows the core to
just handle the task of arbitrating the bus. Initialisation and
pampering of cards is now done by the different bus handlers.
This design also allows MMC and SD (and later SDIO) to be more cleanly
separated, allowing easier maintenance.

mmc: Separate out protocol ops2007-05-01T11:04:18ZPierre Ossman2006-12-24T21:46:55Zurn:sha1:da7fbe58d2d347e95af699ddf04d885be6362bbe
Move protocol operations and definitions into their own files
in an effort to separate protocol handling and bus
arbitration more clearly.
