From: Steffen Trumtrar <str@xxxxxxxxxxxxxx> Hi! The sata_mv driver in barebox only supports the ARMADA-XP and there are not really that many users. Therefore only copy mv6-specific setup from the kernel to the barebox driver. We have some specific hardware combination of ARDAMA-XP and SATA drive that fails in probing the drive on a cold start. Not always but at least in 2 of 10 boots. When the error occurs, the error registers and/or the documentation wheren't really that helpful. The only way out is hard-resetting everything and trying again to enumerate the ATA drive. That's what we do now. While at it, get the phy errata from the kernel and flip some bits in the initial setup that are also set in the kernel driver. Sadly this wasn't enough to fix the probe error. This series was tested on the specific, broken HW combo and with a different combo that didn't (and still doesn't) fail probing.
