[U-Boot] AHCI Update

[Aaron Williams]

Hi,

I am working on cleaning up the AHCI driver which appears to be quite old. I 
am migrating it from SCSI to SATA and was wondering if anyone else is 
interested in this?

So far I made a number of changes to the old driver in order to get it to work 
properly with a JMicrom JMB363 card that I have and a couple of drives. It 
looks like it does not support LBA48 mode among other things.
