[PATCH] Fix EHCI usb. I start to test on a
IXP465 board and I find some errors in the code. This patch fix: - descriptor initizialization (config, interface and endpoint must be one next-to the other when the USB_DT_CONFIG message is send. - FIX little/endian bigendian (introduce the CONFIG_EHCI_DESC_BIG_ENDIAN and the CONFIG_EHCI_MMIO_BIG_ENDIAN) - Introduce the linux version of the usb_config_descriptor and usb_interface descriptor. This descriptor does't contains u-boot extension. Signed-off-by: Michael Trimarchi <trimarchimichael@yahoo.it> Signed-off-by: Remy Böhmer <linux@bohmer.net>
