size_report: Add a report showing total memory use. #97155
Conversation
The current size_report generates "ram" and "rom" reports, but not one
showing the total of all run-time memory used (the "ram" report does not
include memory required to load the code for non-XIP boards).
Summing the existing reports does not work as it double-counts
statically initialized data.
The new "all" report shows the correct accounting of all run-time memory
used.
To support this functionality the "targets" argument has been extended
to allow multiple arguments, for example to generate all three reports:
$ size_report -k ... -z ... --output=. ram rom all
In the JSON output, the location ("ram" or "rom") is included in the
"loc" property for each symbol.

Hello @grahamroff-dev, and thank you very much for your first pull request to the Zephyr project! |

I gave this a go and its output makes sense to me. Example: https://gist.github.com/mbolivar/2ad8f47d115db8be42dc51af2a0e53b3
