## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
This introduce common folder structre and rework scripts & tools
files. The linker scripts were reorganized to use best the current
infrastructure which uses a template to create a final samv7.ld
file based in the current SoC memories and bootloader definitions.
