Hi Bin
Thanks for the reply. I'm working on Intel Denvernton Board. As you suggested
I'm debugging it
using DM PCI now. In the device tree file, I define PCI as this, but I don't
know what is missing so
that AHCI isn't probed
pci {
compatible = "pci-x86";
#address-cells = <3>;
#size-cells = <2>;
u-boot,dm-pre-reloc;
};
In coreboot.h, I define
#define CONFIG_SCSI_AHCI
#define CONFIG_SCSI
#ifdef CONFIG_SCSI_AHCI
#define CONFIG_LIBATA
#define CONFIG_SYS_64BIT_LBA
#define CONFIG_SCSI_DEV_LIST {PCI_VENDOR_ID_INTEL, \
0x19b2}, \
{PCI_VENDOR_ID_INTEL, \
0x19c2}
U-Boot dm tree command shows pci isn't probed.
=> dm tree

x86 has been fully converted to DM PCI, so legacy PCI driver is not supported
now.
Which board are you using? Can you debug why AHCI does not work with DM PCI?
