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
