LS1012A Cryptographic Extensions (CE)

The LS1012A Layerscape processor's Datasheet states that it support ARMV8 Cryptographic Extensions. However, it appears the CE is NOT present on the LS1012A.

 

As an example, on a Cortex A76 (Raspberry Pi5) with CE, running a lscpu yields the following CE related CPU flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm lrcpc dcpop asimddp

 

But running the lscpu on the LS1012A yields the following flags: fp asimd evtstrm crc32 cpuid

I attached the foll lscpu output of both platforms.

Am I missing something, or is NXP's documentation incorrect?

Dear @RiaanGouws
The "Arm v8 Cryptography Extensions" are intended for use on devices with the SEC engine enabled.
Please check the part number of your device, it must include the letter "E" on it.
please share a picture of your device.
