The same file list is now listed 7 times in this linker script, in different variants - hard to maintain.
Can this be factored out? E.g. via include construction, or macros? (Preprocessor would need to be employed explicitly, though.)

Unfortunately we need to reference units 7 times. I created a single source of truth file for hot memory. Macros are defined within linkerscript itself.

@vladyslavmarkovaccenture Can you please explain the background behind this change? Which problem it solves? Ideally, in the commit message and or documentation? |

@rolandreichweinbmw I will add another commit to this PR with changes to documentation. TL;DR functionally it's an expansion of usable memory. All new stuff will be put to SRAM_U by default, "hot" functionality is moved to SRAM_L. Previously SRAM_U was not used (except for 0x400 bytes allocated for NoInit). |
