Subject: [U-Boot] SATA Port Multiplier and AHCI Support
Date: Fri, 14 Feb 2014 18:30:07 -0800 [thread overview]

Hi all,
I am wondering if anyone has tried to deal with SATA port multipliers
inside U-Boot? I am in the process of merging a lot of libata and port
multiplier support from the Linux kernel back into U-Boot since one of
our chips is targeted at NAS devices and our boards use SATA port
multipliers.
This has ended up being a fairly large project. In addition I am needing
to make a lot of changes to the AHCI driver. The first thing I did was
switch it from being SCSI to SATA but there are a significant number of
additional changes required as well since the 1:1 mapping of port to
drives no longer applies.
-Aaron
