> SRU Justification:
>  
> [Impact]
>

>  
> [Fix]
>  
> * Port the mlxbf-pka driver from Ubuntu 22.04 to 24.04.
> * Test to verify the major PKA functionalities are working in 24.04.
> * Create mlxbf-pka driver patch for 24.04.
>  
> [Test Case]
>  
> * Successful build of kernel for ARM64.
> * Check if the PKA devices can be probed.
> * Run the PKA verification test defined by PKAlib and verify the result.
> * Run the PKA performance test defined by PKAlib and verify the result.
> * Run the random number test with the PKA hardware and verify the result.
>  
> [Other]
> * This code is likely to change depending on feedback we received from maintainers.
> 
> [Changes from v1 to v2]
> * Fixed some non-ASCII characters in the source code.
