Booting a NXP kernel with mainline U-boot leads to the following kernel crash:
caam: probe of 30900000.caam failed with error -11 Unable to handle kernel NULL pointer dereference at virtual address 00000004 pgd = 80004000 [00000004] *pgd=00000000 Internal error: Oops: 805 [#1] PREEMPT SMP ARM
This happens because NXP kernel expects MX7 to boot in secure mode, so introduce mx7dsabresd_secure_defconfig that selects CONFIG_MX7_SEC and allows booting a NXP provided kernel successfully.
