I want to create a communication protocol to control any hardware device using the sd port as an in/out port. I've been looking through the code in
/openwrt-xburst/build_dir/linux-xburst_qi_lb60/linux-2.6.32.10/driver s/mmc/,
and i managed to see the commands that the hots (in this case the ben nanonote) sends to a sd card while initializing, writing and reading it. However, the driver I've been reading is a low level code, I need to find the driver that calls the one in the file above and tells it the commands to be sent. So, whereabouts is the driver I should modify in order to send the commands I desire? Thank you in advance.
