How to add kernel support for AHCI devices? There are several CM4 sata hats and mine has an asmedia - but I expect it just needs the AHCI driver.
I saw some references to adding to the inux.aarch64.conf file "CONFIG_SATA_AHCI=y" and build.
Is there anything more than that? (Im waiting for the default build to finish now, there are some 404s on some packages at the moment(
At the risk of conflating two issues, the build failure without any changes is specifically,:

Thanks - can build, but no luck adding AHCI support.
Based on your comment in another thread, I added these options to the projects/RPi/devices/RPi4/linux/linux.aarch64.conf file
CONFIG_ATA=m
CONFIG_SATA_AHCI=m
CONFIG_SATA_MV=m
Though that's just a guess from something Jeff Geerling did. I can build with a PROJECT=RPi ARCH=aarch64 DEVICE=RPi4 make image flash and boot, but no luck loading the module.
insmod ahci
insmod: ERROR: could not load module ahci: No such file or directory
Any suggestions?
Please see if http://chewitt.libreelec.tv/testing/LibreE…h64-12.80.0.tar works?
Success!
What steps should I take next?

Skip the first patch hunk with VERSION changes if on LE12 as I'm on LE13/master branch and GCC things are different. The rest should be the same as the kernels are currently the same in both branches.
You should be able to just respin the image to pick-up the changes.
Worked great - I used editdiff on the patch file and it built and worked just like it should. I'm gonna go pick up some merch!
