[U-Boot] SAAT support in U-Boot ppc4xx
Hi ,
I have u-boot 1.3.1 installed in a sequoia board with ppc4xxEPx. The "pci" command lists out normal PCI cards in the prompt. (Bridge, Multimedia etc.).
But When I use a PCI-SATA card, the s/m gets hangs, most of the time. Else it will not list out the Device in the "pci" command.
In normal Desktop PC , the BIOS support SATA drives. Is there any option to support PCI-SATA card in the u-boot. The same card is listed as a Mass Storage device in my Desktop PC. when I enabled SATA in BIOS. Is there any Workaround to Avoid the Hanging issue.
but One thign I notice is that , the Board is PCi v2.2 Spec and the SATA card (SIL3114) is PCI v 2.3 Spec. Will this give any phase difference problem, that gives this instability. Eventually the linux also can not detect the card (In case Its booted). Any suggestion is appreciated.

In the first step, please update U-Boot and use a recent verison, i. e. v2009.03-rc1; then test again.

Dear Wolfgang Denk,
I have tried with Latest u-boot. ( 2009.03-rc1-00000-g00cc559 ). Still not out of trouble.
Here the condition is worse. It gives machine Check Exception and reboots, repeatedly. Some times hangs at "PCi Scan Display" , else after Displaying *"Net: No ethernet found* " .
The case is same even if there's no PCI card inserted. So it like some modification not complete. Any suggestion is appreciated. Mine is a Sequoia board with 2 PCI slts. (I am testing with the Nand-Booting Option, as I dont have a flash programmer for NOR) .
In the old version , I was getting the u-boot prompt, but not always. The new U-Boot hangs as follows.
U-Boot 2009.03-rc1-00000-g00cc559 (Feb 27 2009 - 16:53:12)

Any suggestion is appreciated. Has anybody got the SATA-PCI working before on PowerPC, or similar situation.
