IIRC these boards use only the host mode of the ISP1362, and this is using just the normal EHCI driver.
Thanks for the reply. Host mode is all I need, so that is OK. But I think I must still be missing something. I grepped the entire U-Boot tree searching for CONFIG_ISP1362_USB, CONFIG_SYS_ISP and CONFIG_SYS_.R5_ISP and found only the definitions I quoted earlier; they don't seem to be used anywhere. And there is no way it could work without using them as the ISP1362 sits on the data bus as a memory-mapped part and the driver would need to know where to find it.
I thought that maybe the distribution I got from blackfin.uclinux.org [1] is missing some files used by those targets, so I downloaded the latest from ftp.denx.de [2], but found exactly the same things there. Is there somewhere else I should look for the code that implements CONFIG_ISP1362_USB and utilizes the defined addresses? Thanks.
