Marius,

I would like to say that thanks for fixing the ata-marvell driver for the 
SuperMicro Sata card on sparc64, atleast the blade 1000.  Your patch has 
enabled the card to detect the disk drive and complete booting.  Not only 
that, I was able to go all the way and create a new partition on the disk, 
newfs it, and mount it.  I was able to copy 1.6gigs of data onto the 
partition, and was able to copy data from the partition to another 
directory within the same partition at a tune of about 40MB/s.

Before that patch, the system was not able to complete booting.

Out of curiosity, ofcourse, what does the patch do?  Does it basically 
disable 64-bit and dma for the driver on sparc64?  This is a PCI-X 133mhz 
card.  It would be a dream to get half the band-width as it is in a 66mhz 
pci slot.

Thanks,  Robert.
