Subject: [Qemu-devel] [PATCH] add a simple 24mhz clock for the versatile
Date: Fri, 30 Mar 2007 11:48:13 -0500 [thread overview]
Message-ID: <460D3F4D.10400@windriver.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 308 bytes --]
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.
