Hi,

I am new to this group. I have a couple of queries regarding the setting of SATA ATA link speed in the linux kernel driver.

1. Do we have any configuration in u-boot to enable reading and writing of the SCR register associated with the ata link? 2. Currently I am not able to read the speed or any other parameters since the reading or writing of the SCR register is not supported. Is it something u-boot does ? 3. Can I pass a boot argument command "libata.force=1.5Gbps" in u-boot prompt as one of the boot arguments?

Thank you for helping. Regards Simon
