The setup looks ok. In io's log output you can see that e.g. the edma
and the mmc1 device both have a client. You can increase io's log
verboseness by adding more (up to seven) '-v' switches. Eventually you
will get the vbus configuration printed.
The reason you don't see any MMC device in /dev is that L4Linux does not
know about the physical devices (yet). You have to pass in a device tree
(FDT) using the 'l4x_dtb' kernel command line option e.g.
l4x_dtb=rom/your_device_tree.dtb
Don't forget to add the device tree to your entry in the modules.list
file. Also make sure to enable CONFIG_USE_OF in your L4Linux configuration.
Best,
Matthias.
