Did you create it yourself? I created the file by myself. But it's nothing more than setting up register base addresses similar with ehci-ixp4xx.c ...

I'll take a look later this week. thanks, Chris ----- Original Message ----- From: "Stefan Roese" To: u-boot at lists.denx.de Cc: "Chris Zhang" Sent: Sunday, January 3, 2010 9:45:04 PM Subject: Re: [U-Boot] Sequoia EHCI Hi Chris, On Saturday 02 January 2010 23:25:50 Chris Zhang wrote: > I was trying to get EHCI running on sequoia board (ppc440epx).
