device mount point/driver access
This question deals with device mounting - mapping a mount point 'back' to a device driver.
I have a running Beagleboard utilizing Angstrom distribution RFS via NFS on my Slackware (12.1) based laptop. I can access the 'data' partition (1) of an on-board SD via /media/card mount point. My goal is to pare down the RFS (from the ~280MB), making it as small as possible with the minimum drivers installed to get at key HW, such as the SD.
I successfully created a new 'teeny' RFS with minimum capability & hit a road block trying to install SD support. Going back to the Angstrom RFS, I could not determine a mount point in (/dev) and which kernel driver(s) are required. Since the SD can be removed, I'm assuming it is a 'hotplug' device thus handled by UDEV? I found SD references in UDEV related scripts but could not find mention of a specific device driver.
I'm able to build the kernel (2.6.29)/drivers & thus observe diagnostics when the drivers are installed; I did this for the SD/MMC related drivers that are built-in to the kernel. I did not see any diagnostic output - even though I can get at the card as mentioned above.
I'm able to wade thru /proc & /sys & observe SD/MMC references but I'm not expert make the mount point linkage - my goal is to find (and install) the required driver for SD access. I can even bypass the hot-plug capability for my environment.
Any help here is appreciated ..
