As promised, here is the patch broken down into smaller pieces. The
patch is now divided into six distinct parts:
* Protocol definitions.
* SD card initialisation.
* Reading read-only switch.
* Getting SCR register.
* Exposing SCR register through sysfs.
* Wide (4-bit) bus support.

Protocol definitions.
The basic commands needed for the later patches. The R1_APP_CMD seems to
be misdefined in protocol.h so this patch changes it.
Index: linux-sd/include/linux/mmc/mmc.h
===
--- linux-sd/include/linux/mmc/mmc.h
SD card initialisation.
This patch contains the central parts of the SD support.
The system first tries to detect MMC cards, and if none are found then
it procedes to look for an SD card. This is incorrect acording to SD
specifications but I find it odd that MMC is supposed to cope with SD
Read-only support.
This patch adds a new callback for the drivers to facilitate reading the
SD card read-only switch. If the callback is not provided then a warning
will be printed and it will default to write-enable.
The read-only switch is a host enforced read-only so the MMC block layer
has
SCR download.
This patch downloads the SCR register from the card. Unlike the other
registers this one is transfered over the data bus. That required some
changes to other routines to allow a card to be selected after the host
was aquired.
This is one of the more error prone parts. The
SCR sysfs access.
This provides access to the SCR register via sysfs. Since the latest bk
contains some changes to the sysfs part this probably needs updating.
The patch is trivial though so it should be easy.
Index: linux-sd/drivers/mmc/mmc_sysfs.c
Wide bus support.
This adds 4-bit bus support to the MMC layer. It is designed to
(hopefully) be compatible with a future 4-bit MMC implementation. This
is done by seperating the three different instances of bus width defines:
* Protocol definition: SD_BUS_WIDTH_x
* SCR contents:
