[U-Boot] [PATCH 1/1] colibri_imx7_emmc: enable CONFIG_ARMV7_BOOT_SEC_DEFAULT
From: Igor Opaniuk igor.opaniuk@toradex.com
Enable CONFIG_ARMV7_BOOT_SEC_DEFAULT by default to avoid a kernel crash when booting NXP linux kernels in non-secure world, when job ring device allocation is done by CAAM hw accelerator driver:

I rather prefer if mainline U-Boot prefers what makes sense for mainline kernel (and that is non-secure).
Booting in secure mode can be also done using bootm_boot_mode environment variable.

Booting in secure mode can be also done using bootm_boot_mode
Just tested with env var (wasn't aware about this var) - it works also, thanks for the suggestion.
Testing was done with the default pre-built NXP kernel from Kynetics AOSP package for Colibri iMX7, probably I'll just add a command for setting a proper value for bootm_boot_mode before parsing/booting stuff from Android Boot Image (where Kynetics people usually are putting NXP kernels inside);
So just ignore this patch, thanks!
environment variable.
