[U-Boot] [USB EHCI PATCH 0/2] USB ehci pci initial support

[Remy Bohmer]

Hello Michael,

2008/12/17 Michael Trimarchi <trimarchi at gandalf.sssup.it>:
> Add USB ehci pci support. This patch doesn't include any
> pci_ids and it is not tested on real hardware. To use it
> add (for example) the following in the board configuration file:
>
> #define CONFIG_CMD_USB 1
> #define CONFIG_USB_STORAGE 1
> #define CONFIG_USB_EHCI
> #define CONFIG_USB_EHCI_PCI 1
> #define CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS 2
> #define CONFIG_LEGACY_USB_INIT_SEQ 1
> #define CONFIG_PCI_EHCI_DEVICE  1

I think that this kind of information should be put in the toplevel README file.
A note where to put the PCI-ids is also nice.

Kind Regards,

Remy
