Enabling CAAM in LS1043A Yocto

Hi,

I want to use SEC interface of LS1043A on TQMBLS10XX to use with OpenSSL. I did the kernel configuration as in this page. After that, in /lib/modules/${uname -r}/modules.builtin I see these modules:

  • kernel/drivers/crypto/caam/error.ko
  • kernel/drivers/crypto/caam/caam.ko
  • kernel/drivers/crypto/caam/caam_jr.ko
  • kernel/drivers/crypto/caam/caamalg_desc.ko
  • kernel/drivers/crypto/caam/caamhash_desc.ko

But I can't see the line below in dmesg.

caam algorithms registered in /proc/crypto

You could use the attached Linux Kernel configuration file, which is the defconfig file for Linux Kernel 5.4.47 in LSDK 20.12 release.

Please configure CAAM as the following.

I inserted config lines into defconfig in meta-tq/recipes-kernel/linux/linux-tq-5.4/tqmls10xxa. However when I execute zcat /proc/config.gz | grep CAAM on new image, I get the output below:

I added these inside defconfig in meta-tq/recipes-kernel/linux/linux-tq-5.4/tqmls10xxa but some of them are not included in image as you can see below.
