MPC8360E USB Host Controller Driver

In the manual, they told that this controller does not belong to UHCI or OHCI standard. Yes, you can call it FHCI if you like. :) I have doubt that whether Freescale has its own USB standard. The interface is stated clearly in the UM. Please give the link or patch for that driver. There is an 8360 host driver in Freescale LTIB BSP. Please find it on www.freescale.com, if it has been released. Could you give a direct link ?

uCLinux for PPC: Bug in autoconf.h creation
I would suspect CRLF issues..

Wireless Linux(802.11) for Embedded PowerPC
On Thu, Sep 07, 2006 at 09:23:08AM +0800, Chun Chung Lo wrote: Also I cannot see any drivers existing in the upstream kernel are really support the Intersil Prism 2 WLAN cards (my card is differ from those Orinoco cards and Hermes cards, also the drivers are also differ a lot). I think you may be mistaken. The orinoco drivers in the upstream kernel seem to support all the same device IDs as are supported in the linux-wlan code. If your card is missing, it is likely a simple matter of a missing device ID. But, major code changes are probably not necessary. (USB-based devices may be an exceptionsee http://www.nongnu.org/orinoco/ for experimental support.) If you are going to use Intersil Prism 2 cards/chips, I would suggest you to use the linux-wlan driver (but seems this driver does not support AP mode yet...) Please don't encourage people to patronize dead projects when the upstream kernel should work for them. Thanks, John -- John W. Linville linville at tuxdriver.com
What is this flat device tree
Can anybody explain to me what the flat device tree is? The phrase comes up often but I can't find a definition for it anywhere on the web. TIA, Alex

See Documentation/powerpc/booting-without-of.txt in the kernel tree. It's basically a representation of an Open Firmware device tree that has been flattened and given to the kernel when it boots. For platforms without Open Firmware, it needs to be constructed by the boot loader, or using the Device Tree Compiler (DTC). josh
