+config LD_NO_RELAX
+       bool "Disable linker relaxation"
+       default n
+       help
+         Enable this function to disable link-time optimizations.
+         The default linker behavior is to combine identical literal
+         values to reduce code size and remove unnecessary overhead from
+         assembler-generated 'longcall' sequences.
+         Enabling this option improves the link time but increases the
+         code size, and possibly execution time.
+
+config S32C1I_SELFTEST
+       bool "Perform S32C1I instruction self-test at boot"
+       default y
+       help
+         Enable this option to test S32C1I instruction behavior at boot.
+         Correct operation of this instruction requires some cooperation from hardware
+         external to the processor (such as bus bridge, bus fabric, or memory controller).
+         It is easy to make wrong hardware configuration, this test should catch it early.
 
+         Say 'N' on stable hardware.
