There isn't much SeaBIOS info in that log - can you recompile with

The equivalent patch in SeaBIOS would look like:
--- a/src/ata.c
+++ b/src/ata.c
@@ -841,7 +845,8 @@ ata_init()
int count=0;
int bdf, max;
foreachpci(bdf, max) {
- if (pci_config_readw(bdf, PCI_CLASS_DEVICE) != PCI_CLASS_STORAGE_IDE)
+ u16 class = pci_config_readw(bdf, PCI_CLASS_DEVICE);
+ if (class != PCI_CLASS_STORAGE_IDE && class != PCI_CLASS_STORAGE_RAID)
continue;
if (count >= ARRAY_SIZE(ATA.channels))
break;
