-config DEBUG_RODATA
- bool "Make kernel text and rodata read-only"
- depends on MMU && !XIP_KERNEL
- default y if CPU_V7

- If this is set, kernel text and rodata memory will be made
- read-only, and non-text kernel memory will be made non-executable.
- The tradeoff is that each region is padded to section-size (1MiB)
- boundaries (because their permissions are different and splitting
- the 1M pages into 4K ones causes TLB performance problems), which
- can waste memory.
