Our IP Core does all the low level protocols in Hardware. The
cards come up as memory mapped. It will automatically select
the highest supported protocol, up to 8 bit for the new MMC
cards. I have written a boot loader based on the xilinx fat
fs libraries - basically just writing a read_sector function
and than opening a file using the xilinx library and copying
the file to SDRAM and executing it. Very trivial.

Now it would be nice to have a device driver for ucLinux that
would have the same type of interface. That should help to have
any memory mapped boot device mountable ...
