Subject: [PATCH] sh: sh7372 SH4AL-DSP probe support
Date: Wed, 12 Jan 2011 10:54:21 +0000 [thread overview]
Message-ID: <20110112105421.11079.83096.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
Add probe support for the sh7372 SH4AL-DSP core.
The most common use case for this is when the system
boots from the ARM core in the sh7372 and uses the
SH core for application offload as a slave CPU.
May also be used to boot the sh7372 from the SH core.
