Hi York,

This change was required to provide the flexibility of enabling DDRC1/CPC1 by
SC3900/DSP core as DDRC1 is used by Starcore. SC enables CPC1 as per their requirement.
PPC core use DDRC2, so it enables DDRC2/CPC2.

Do you suggest mentioning it in the commit message also?

Thanks and Regards,
Shaveta

What's the user's case for enabling selected CPC?
