[U-Boot-Users] IDE Access from U-Boot

[sudhakar rajashekhara]

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:
