To be fair, I'm not 100% certain about backporting any of this.  We did 
the initramfs in response to the newer kernels (ie upstream) building 
something as modules and not built in.  And we moved to that model in 
6.18 (master/wrynose).

If there is something in scarthgap for 6.12 that requires this then we 
should just update our 6.12 kernel to build the correct thing and not 
need the initramfs.  We haven't tested any of this code under scarthgap 
and I'm not comfortable just shoving this in.  We need to try and keep 
scarthgap somewhat stable and not do things like this.

We should be able to have a config fragment that only applies for j722s 
when building the kernel to configure it exactly how we want for just 
j722s.  No need to shoehorn in the initramfs for this.
