Bug#1032362: Kernel doesn't find SATA ports on Softiron 1000 (arm64 Seattle)

[Steve McIntyre <steve@einval.com>]

Source: linux
Version: 6.1.12-1
Severity: important

Hey folks,

I've just upgraded my Seattle-based system to bookworm and it no
longer finds the onboard AHCI SATA storage so it stops at an initramfs
prompt. Going back to the current bullseye kernel (5.10.162-1), it all
works just fine.

As far as I can see, the DTB hasn't changed in this area. The
non-booting system still has plausible-looking entries for the sATA
controllers:

drwxr-xr-x    2 0        0                0 Mar  5 00:00 /sys/firmware/devicetree/base/smb/sata@e0300000
drwxr-xr-x    2 0        0                0 Mar  5 00:00 /sys/firmware/devicetree/base/smb/sata@e0d00000

I'll try to bisect and see where things stopped working...
