Consider read-only data when determining where flash starts #92
Description
The current logic to determine flash start address finds the first executable segment and considers that as the start of data that goes into flash. This breaks if the CRT0 header goes into a data segment instead. The easiest fix seems to be to consider all read-only segments, not just executable ones, as flash.
This works for all the use cases I have, but there may be unintended consequences if I missed something?
