TMS320F28388D: How can I integrate the TI FlashAPI with my application that uses the COFF output format?

I'm working on a new project that uses the COFF output format. I need to use the TI Flash API. The TI Flash API is current provided as a compiled library using the EABI output format.

Moving to using the EABI output format is not an option because there is existing code that makes use of the relocatable expressions feature that is no longer supported in EABI. Is there a way for us to access to the TI Flash API in a format we can use? Either the compiled libraries using the COFF format or source code that we can build? Either that or is there a way to convert a library using the EABI format to use the COFF format? I would love if it was as easy as just updating old code, but that will take too long in this case.
