I still see build error with multiple imx boards:

===================================================
       arm:  +   mx7dsabresd_qspi
+arch/arm/mach-imx/imx_bootaux.c:18:32: error: 'get_host_mapping' defined but
not used [-Werror=unused-function]
+ static const struct rproc_att *get_host_mapping(unsigned long auxcore)
+                                ^~~~~~~~~~~~~~~~
+cc1: all warnings being treated as errors
+make[2]: *** [arch/arm/mach-imx/imx_bootaux.o] Error 1
+make[1]: *** [arch/arm/mach-imx] Error 2
+make: *** [sub-make] Error 2


Thanks and regards,
