I modified Linux kernel to work in non-secure world.
Linux version 3.10.17-svn1666 / (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #2 Thu Apr 2 19:43:43 KST 2015
It print kernel panic messages with back-trace when kernel is booting in non-secure.
Exactly, on caam_rng_init process as bellow messages
I dont know what i do now.
I have set the CSU_CSL17 register to 0x00ff00ff so that CAAM can be accessible in both non-secure and secure world.
should I check more CAAM's register like that Secure Memory Access Groups (SMAG) Register, Master Configuration Register (MCFGR) ?
please help me~~~
