[PATCH] sh: sh7372 SH4AL-DSP probe support
From: Magnus Damm <magnus.damm@gmail.com>
Date: 2011-01-12 10:54:21
From: Magnus Damm <redacted> 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.
