-Unlike the instructions for [wiki:Developer/Removing_a_BSP Removing a BSP], these instructions assume the reader is familiar with RTEMS Developer Practices and provides a checklist as opposed to detailed instructions. An important facet of removing an architecture is that it will require changes to multiple areas of the RTEMS Project spread across multiple repositories. This makes it more complicated and the developer removing the architecture should be careful, use grep, and update this page as other areas to update are identified:

-* File a Trac ticket - This should list all tickets associated with removing BSPs within this architecture. All commit messages associated with removing the architecture should reference this ticket number. See [https://devel.rtems.org/ticket/2443 ticket 2443] for a simple example.
+HINT: In order to be sure you have gotten all the references, be sure to grep for architecture specific defines that are predefined by GCC in the entire source base of each repository.
