I changed U-boot as suggested:

--- a/include/configs/mx7_common.h
+++ b/include/configs/mx7_common.h
@@ -94,10 +94,7 @@
 #define CONFIG_CMD_FUSE
 #define CONFIG_MXC_OCOTP

-/*
- * Default boot linux kernel in no secure mode.
- * If want to boot kernel in secure mode, please define CONFIG_MX7_SEC
- */
+#define CONFIG_MX7_SEC
 #ifndef CONFIG_MX7_SEC
 #define CONFIG_ARMV7_NONSEC
 #define CONFIG_ARMV7_PSCI


but still see only one core brought up in the kernel:

[    0.003051] /cpus/cpu at 0 missing clock-frequency property
[    0.003076] /cpus/cpu at 1 missing clock-frequency property
[    0.003092] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[    0.003157] Setting up static identity map for 0x80008280 - 0x800082f0
[    0.005152] Brought up 1 CPUs
[    0.005169] SMP: Total of 1 processors activated (48.00 BogoMIPS).

I am booting 4.5-rc5 on a imx7d-sdb board.

Any ideas on how to bring up the second core?
