Kumar, thanks for the Info, that helps. Do you know if in this kernel Version the MPC5200 USB Bug is already handled?
I refer to errata document MPC5200E.pdf (I think rev. 06/2005) in which its stated that the frame_no and pad1 words are swapped in the processors OHCI Area. I saw in some earlier 2.4 kernel that in /drivers/usb/host/ohci.h the members frame_no and pad1 of struct ohci_hcca were swapped. maybe thats not necessary anymore ? Im using this driver to support our embedded system modules equipped with the 5200 (see the EM1 board on www.men.de for specs). regards, Thomas Kumar Gala wrote: > Well for the 5200 Thomas should be using include/linux/fsl_devices.h > > If/when 4xx coverts over to platform devices we could have an > equivalent include file if truly needed. > > - kumar > > On Aug 9, 2005, at 11:58 AM, John Otken wrote: > >> My patch to add on-chip OHCI support to the 440EP adds >> an asm/usb.h reference to 4xx/ibm440ep.c.
