Describe the contribution
Add a compile time assert to ensure that this value is actually a power of two-1 (i.e. an LSB-justified bit mask).
Notes in the comments that it serves as both a numeric limit and a mask.
Fixes #1365
Testing performed
Build CFE normally, sanity check.
Also Intentionally set
CFE_RESOURCEID_MAX
to an invalid value and confirm that the compile time assert caught it.Expected behavior changes
Will catch the case if the
CFE_RESOURCEID_MAX
value changes in such a way that makes it not usable as a bit mask as intended.System(s) tested on
Ubuntu 20.04
