Somehow the code to read the read-only switch of SD cards got lost
in the reorganisation.

mmc: don't call switch on old cards2007-06-07T07:25:58+00:00Pierre Ossmandrzeus@drzeus.cx2007-05-31T20:25:11+00:00urn:sha1:3373c0ae6a51085b10a95fd9d2214a9995ef7563
Make sure we don't call the switch function on cards too old to
support it. They should just ignore it, but some have been reported
to lock up instead.

mmc: fix broken if clause2007-06-07T07:25:54+00:00Pierre Ossmandrzeus@drzeus.cx2007-06-06T18:23:25+00:00urn:sha1:71651297a448289353b2493c6c3c183f9be7be7c
Fix a broken if clause which was causing SD cards to go into
4-bit mode even if the host did not support it.

mmc: use lock instead of claim in debug check2007-05-08T20:42:57+00:00Pierre Ossmandrzeus@drzeus.cx2007-05-08T20:35:17+00:00urn:sha1:1efd48b3ae8f89a1d04f1e36be96764d7bf43ae9
As mmc_detect_change() can be called from irq context, using
claim (which can sleep) is inherently unsafe. Use the host
spinlock instead, which also is faster.

Change Kconfig objects from "menu, config" into "menuconfig" so
that the user can disable the whole feature without having to
enter the menu first.

mmc: support unsafe resume of cards2007-05-01T14:00:02+00:00Pierre Ossmandrzeus@drzeus.cx2007-05-01T14:00:02+00:00urn:sha1:6abaa0c9fec563538f2a28a682af8c89bb9b125c
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.

and one that acts on them.
