TI DSP updates

These are the changes I made to use the latest Codec engine, DSP modules, etc. 
for OMAP3530 to build. Tested and working with gstreamer-ti on an Always 
Innovating Touch Book with linux-omap_2.6.29 kernel / Angstrom...

To actually get the dmai working on the TouchBook, I also needed this patch:

violino:~/oe/tmp/work/beagleboard-angstrom-linux-gnueabi/ti-dmai-svnr295-r43a/TAG_2_00_01_04/dmai/packages/ti/sdo/dmai/linux>

               *device = Cpu_Device_OMAP3530;
       }

The TI video decoders support MPEG4 but don't recognize XViD by default. TI 
doesn't claim that XViD is supported, but applying this patch to the decode 
module allows the decoder to recognize it, and it works with the few samples 
I've tried:

To get a working codec server on the Touch Book, which has 256MB of RAM, I had 
to modify the default server config:

violino:~/oe/tmp/work/beagleboard-angstrom-linux-gnueabi/ti-cs1-omap3530-10142-r4/dvsdk_3_00_01_42/cs1omap3530_1_00_01/packages/ti/sdo/server/cs>

Thank you for your work on this! Your work does seem to be based on an 
outdated OE checkout, could you try to rebase it on the current 
org.openembedded.dev branch?

To move the memorymap more stuff has to get changed, but there's an 
easier way that also works with 512MiB and 1024MiB RAM:

put 'mem=80M@0x80000000 mem=128M@0x88000000' in your bootargs and make 
sure your kernel has the arch-has-holes.diff applied to make that 
memoryhole work.

Ah, I thought I had rebased with HEAD just before I posted. But sure, I'll try 
updating again.

Interesting. I guess that's more future-proof but currently no OMAP3530 can 
have more than 256MB of RAM... Also, not sure what else you're referring to 
that needs to be changed. The dsplink driver doesn't care. The codec server 
only needs to know where the end of memory is, and it arranges the rest of the 
map itself. It chose to use only 29M of memory, and I can't complain about 
that, better than eating up 40M. Here's the datasheet it generated for this 
codec server:

http://highlandsun.com/hyc/cs.x64P.DataSheet.html

The gstreamer ticodecplugin just needs to be pointed at that server.tcf file 
to use the same config. If I'm missing the point you're making, please explain 
again, thanks.

If I had known about that memory hole trick I would probably not have bothered 
rebuilding any of this, could've just downloaded a new codec combo and run 
with it. Live and learn...
