Falling wall

I have a 5 metre piece of a low brick walled area which needs some sort of repair. I'm aware the best idea would be to do the lot I'd see this as a temporary arrangement until the courtyard is relandscaped. The wall is presently about 500 high and I'm envisaging levelling it with a lower area which is about 350 high. I thought I had a photo but don't. It's a rental so can't just drop by. Open to suggestions as to a simple way to do this.
