SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32

Syntax for every __weak and __packed

I am using STMCubeMX 5.2.0. That is the latest version. The issue persists. I just created a project for the Nucleo L476RG board. And there are the quotes again. Should I attached a screenshot?

I hope you do not expect to see syntax errors reported by GCC. Instead of being properly escaped, the quotes are stripped at some point and they are not passed to GCC. That of course is a bug in itself (!!!). Anyhow, for the CDT Indexer, the quotes are present, hence it cannot understand the syntax and it cannot properly index the files.

The CDT indexer is still being sabotaged - be it by STMCubeMX or by OpenSTM32. This is harmful to the usability of OpenSTM32.
