Bare metal write to sd card using adma2

I have successfully read from a sd card using the bootfile example mmc.c file that uses disk_read with adma2 transfer.

Now I want to extend this to write to the sd card but there is no matching disk_write function using adma2 in the example code.

Can anyone supply this code, or know where I can find it?

Thanks

There is diskio.c file in the vivado installation directory where you can find disk_read and disk_write functions.
