Aligning ACS Linux Kernel Version with LTS Distributions for SystemReady band Compliance #568
Description
SystemReady band compliacne helps ensure that users can install and run generic off-the-shelf standard operating system images unmodified out-of-the-box, while also ensuring forward and backward compatibility ( i.e., Old OSs can run on new hardware, and new OSs can run on old hardware, without customization). Therefore, it makes sense to align the ACS Linux kernel version with LTS distros instead of upgrading kernel to a newer version that hasn't been used by LTS distros.
Currently, the latest LTS distros, such as SLES/openSUSE (16), RHEL/CentOS (10), and Debian (13), are all based on 6.12, so this is the right time to use 6.12 as our ACS Linux kernel.
The kerenel version in mainline (arm-systemready repo top of treee) is now 6.16, we need to downgrade it to 6.12. Note that the latest SystemReady band ACS release (3.1.0) uses Linux kernel 6.10.
