[microblaze-uclinux] Non-PCI AHCI SATA driver in uclinux

["Eugene Peng" <Eugene.Peng@xxxxxxxxxxxx>]

Hello!

I am investigating into the possibility of developing a driver for an
AHCI SATA Controller without the PCI interface. 

First of all, is there AHCI support in the current 2.4.x distributions
for uclinux? From what I gathered, AHCI is fully supported in linux
2.6.19, so is there a way to port it over?

John: you seem to have dabbled with a non-PCI driver based on libata
before as I found in the conversation on this link:
http://groups.google.com/group/linux.kernel/browse_thread/thread/aab9d71
28e12621c/13b0a3a6f265e32b?lnk=st&q=sata+uclinux&rnum=3#13b0a3a6f265e32b
Were you able to get further on that? 

Jeff Garzik(creator of libata) mentions that libata in 2.6.x supports
generic bus interface rather than being PCI-specific. So preferably I
should be working with 2.6 kernel. Can I already do that on microblaze,
or are there still issues to be resolved?

Any comments or suggestions will be greatly appreciated!

Eugene
