Hello,
Background: I am running uCLinux on a processor embedded in a FPGA, and need a AHCI support for a device not on PCI but my own custom bus.
The kernel version is 2.6.20, so there is an AHCI driver under libATA.
Question: What type of linux device driver should I enumerate my modified AHCI driver as?
I am still a beginner to linux and driver development.
From what I understood in the book Linux Device Drivers,
I can develop it as a Block storage type device.
So is this the solution: convert driver type from PCI to Block?
From the user's point of view, will accessing it be different?
Thanks, Eugene
