[U-Boot] EHCI and OHCI deriver in u-boot-2009.03

[xiaoguizi007 <xiaoguizi007@163.com>]

Hi,
I am using diver of EHCI and OHCI in u-boot-2009.03. My HC is ISP1564, this HC has multi-function, it supports OHCI and EHCI. So, I think that maybe we must define new macros in my NSB405EP.h which is in ./include/config dir. But I find there are many functions in usb_ohci.c and usb_ehci_core.c defined as the same name,so I do not know how to use them at the same time in my project to support both OHCI and EHCI. Any way, another problem is that I can scan 2 functions in pci bus while using cmd: pci. As know that when HC power on, the ports ownership is under OHCI, how can I switch the owmship to EHCI???(write bit OCR of HcControl may not useful while I used).
Also, another problem is that: u-boot allocate base address and size for both OHCI and EHCI while HC be found on pci bus. This step has not problem. OHCI base = 0x80000000, size = 0x1000, EHCI base = 0x80001000, size = 0x100. Then I used command "md" to display the memory on 0x80000000(ohci) has no problem. But When display memory 0x80001000(ehci), u-boot go to dead as belows :
  =>md 80001000
  =>80001000: 20009500
then the terminal will not display any more info and will not receive any keys you pressed.Maybe u-boot go to dead this time. So I do not know why.
Can anybody help me or provide me some useful info about using muti-function usb HC in u-boot ???
 
Thanks,
