The CCP device is part of the AMD Secure Processor. In order to expand the
usage of the AMD Secure Processor, create a framework that allows functional
components of the AMD Secure Processor to be initialized and handled
appropriately.

It looks like ccp-platform.c has morphed into sp-platform.c (judging by
the compatible string and general shape of the code), and the original
ccp-platform.c is no longer built.

Shouldn't ccp-platform.c be deleted by this patch?


Good catch. Both ccp-platform.c and ccp-pci.c should have been deleted by this patch. I missed deleting it, will fix in next rev.
