It has been a long-term demand for having a default crashkernel value for each kernel build. This helps to manage kernel's crashkernel usage by kernel version and provide users a reference default value. RHEL kernels support a `crashkernel=auto` cmdline param. And kernel have a built-in default value used when `auto` is specified. Many attempts are made to push this upstream. Recent attempt to push this upstream raised a lot of discussions [1]. Upstream is not accepting this `crashkernel=auto` design. So after more discussions, instead of adding a default value in kernel, just add a config that packaged with kernel is more doable. Other packages, like kexec-tools[2], can use this as a reference and update kernel cmdline param.
