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 Freescale/nxp platform code. Some driver code still be kept and may clean up later since it is possible reused by other SoC.
