From: Gokul Praveen <g-prav...@ti.com> KASLR, or Kernel Address Space Layout Randomization, is a security feature in the Linux kernel that randomizes the memory location where the kernel is loaded during boot.
OP-TEE RNG is a Random Number Generator (RNG) component within the Open Portable Trusted Execution Environment (OP-TEE) which provides a random number to U-BOOT and U-BOOT provides this random number as seed value to the LINUX kernel for KASLR. Add KASLR OPTEE RNG support across K3 devices by enabling the required configs. Signed-off-by: Gokul Praveen <g-prav...@ti.com> --- v2<==> v1 =========== * Added 'if' condition for configs to avoid enabling this feature in R5.
