From: Frank Li <[email protected]> The Vybrid M4 NOMMU platform support was added as a proof-of-concept and has not seen practical use in production systems.
Commercial users and hardware vendors migrated to Zephyr or other RTOS solutions years ago, leaving the NOMMU platform support effectively unused and unmaintained. Remove the obsolete support to reduce maintenance burden and simplify the code.
