[Qemu-devel] [PATCH] add a simple 24mhz clock for the versatile

[Jason Wessel]

This patch implements a simple 24mhz clock for the versatile board such 
that functions in the linux kernel can make use of these stamps.  An 
example user of this is the printk time stamps when using the "time" 
parameter on the kernel boot line.
