There was no need to re-define these structures for the current series of the OMAP35x processors. Hence, it was left as it. >> BTW, why can't the dsp code detect if the DSP is there or not? (Assuming you mean the code running on ARM that looks for the DSP/SGX/...) The detection was based on the chip ID. This happens to be same for OMAP34XX and OMAP35X. ~sanjeev -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tony Lindgren Sent: Wednesday, August 06, 2008 2:37 PM To: Kridner, Jason Cc: '[EMAIL PROTECTED]'; 'linux-omap@vger.kernel.org' Subject: Re: [PATCH] Added support for OMAP35x processor series * Kridner, Jason <[EMAIL PROTECTED]> [080805 17:12]: > No, ROM CRC is useful for detecting between some device revisions, but not > OMAp3430 vs OMAP3530. > > ----- Original Message ----- > From: Koen Kooi <[EMAIL PROTECTED]> > To: linux-omap@vger.kernel.org <linux-omap@vger.kernel.org> > Cc: Kridner, Jason > Sent: Tue Aug 05 05:10:40 2008 > Subject: Re: [PATCH] Added support for OMAP35x processor series > > > Op 5 aug 2008, om 11:50 heeft Igor Stoppa het volgende geschreven: > > > On Tue, 2008-08-05 at 15:09 +0530, ext Premi, Sanjeev wrote: > >> This patch is needed to ensure that we can make decisions based on > >> the processor capabilities. > >> E.g.

Well if there's no way to detect certain omaps during runtime, please patch arch/arm/plat-omap/common.c to have something like struct omap_globals omap3503_globals. BTW, why can't the dsp code detect if the DSP is there or not?
