Hi All,

We are trying to boot Linux from SATA 150 Tx2plus Promise HDD using U-Boot from a MPC8280 board. The ATA card is a 33Mhz PCI card. After U-Boot comes up, it's able to detect the PCI card and also identifies the IDE device. But the IDE initializations of U-Boot fails. Is the memory mapping for the Promise device correct? How can I confirm it? Following is the U-Boot log:
