Hi,
it's working. I modified the testing-USB branch to run against a PCI OHCI controller (Philips ISP1561) on the APC405 board (PowerPC PPC405GPr).
Enumeration and USB storage is working. I do not dare to say 'working well'.
The main changes concern endianess fixes. The former code only supports OHCI controller with the same endianess as the CPU. The other fix allows a offset to access the system RAM by the busmastering OHCI controller. I called this constant CFG_PCIRAM_BASE. But the name is a little bit confusion, isn't it?
Here are my (first) questions: 1) What do I have to do in usb_board_stop() and usb_board_init_fail()? My current code can only initialize the OHCI controller once. A 2nd 'usb start' does not find any devices.
2) I had to disable the 'return -1' statement for an unfinished urb in sohci_submit_job(). Why isn't it finished?
Please do not blame me for the board dependent code still in the usb_ohci.c file. I will move it later.
The modified code is not tested on any other board (e.g. with on-chip OHCI controllers). I might break other boards.
