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.

Just curious are you enabling the kaslrseed command for this build? It
looks like you're using TI's evil vendor scripts but I assumed the
kaslrseed command was disabled.
Can you elaborate more on this,Bryan?
Actually, we are not using the kaslrseed device tree property. Is that
what you meant,Bryan?
