From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Wed, 12 Jan 2011 10:54:21 +0000 Subject: [PATCH] sh: sh7372 SH4AL-DSP probe support Message-Id: <20110112105421.11079.83096.sendpatchset@t400s> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org From: Magnus Damm 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.
