pussuw opened a new pull request, #6490:
URL: https://github.com/apache/incubator-nuttx/pull/6490

   The old implementation needed a contiguous memory block for user
   ROM/RAM. This is because there was only 1 L3 page table which can only
   map a contiguous memory area.
   
   Also, remove the PMP configuration which just complicates things,
   rely on the MMU mappings instead.
   
   ## Summary
   Minor change to CONFIG_BUILD_PROTECTED for mpfs target
   ## Impact
   Allows mapping RAM/ROM from different, non-contiguous memory locations
   ## Testing
   icicle:pnsh
