* usb.h: use standard __LITTLE_ENDIAN from Linux headersMike Frysinger2009-01-28-2/+2
| | | | | | | | | Rather than forcing people to define a custom "LITTLEENDIAN", just use the __LITTLE_ENDIAN one from the Linux byteorder headers that every arch is already setting up. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Remy Bohmer <linux@bohmer.net>

* USB: descriptor handlingStefan Althoefer2008-12-09-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, I found a bug when working with the u-boot USB subsystem on IXP425 processor (big endian Xscale aka ARMv5). I recognized that the second usb_endpoint_descriptor of the attached memory stick was corrupted. The reason for this are the packed structures below (either u-boot and u-boot-usb): -------------- /* Endpoint descriptor */ struct usb_endpoint_descriptor { unsigned char bLength; unsigned char bDescriptorType; unsigned char bEndpointAddress; unsigned char bmAttributes; unsigned short wMaxPacketSize; unsigned char bInterval; unsigned char bRefresh; unsigned char bSynchAddress; } __attribute__ ((packed)); /* Interface descriptor */ struct usb_interface_descriptor { unsigned char bLength; unsigned char bDescriptorType; unsigned char bInterfaceNumber; unsigned char bAlternateSetting; unsigned char bNumEndpoints; unsigned char bInterfaceClass; unsigned char bInterfaceSubClass; unsigned char bInterfaceProtocol; unsigned char iInterface; unsigned char no_of_ep; unsigned char num_altsetting; unsigned char act_altsetting; struct usb_endpoint_descriptor ep_desc[USB_MAXENDPOINTS]; } __attribute__ ((packed)); ------------ As usb_endpoint_descriptor is only 7byte in length, the start of all odd ep_desc[] structures is not word aligned. This makes wMaxPacketSize of these structures also not word aligned. ARMv5 Architecture however does not support non-aligned multibyte data type (see A2.8 of ARM Architecture Reference Manual).

* fix USB initialisation procedureRemy Bohmer2008-10-14-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | The max packet size is encoded as 0,1,2,3 for 8,16,32,64 bytes. At some places directly 8,16,32,64 was used instead of the encoded value. Made a enum for the options to make this more clear and to help preventing similar errors in the future. After fixing this bug it became clear that another bug existed where the 'pipe' is and-ed with PIPE_* flags, where it should have been 'usb_pipetype(pipe)', or even better usb_pipeint(pipe). Also removed the triple 'get_device_descriptor' sequence, it has no use, and Windows nor Linux behaves that way. There is also a poll going on with a timeout when usb_control_msg() fails. However, the poll is useless, because the flag will never be set on a error, because there is no code that runs in a parallel that can set this flag. Changed this to something more logical. Tested on AT91SAM9261ek and compared the flow on the USB bus to what Linux is doing. There is no difference anymore in the early initialisation sequence.

| | | | | | | | A new, Windows compatible init sequence was also backported from Linux 2.6, but disabled with #undef NEW_INIT_SEQ as it wouldn't change the behaviour of the memopry sticks we tested. Maybe it's not relevant for mass storage devices. For recerence, see file common/usb.c, function usb_new_device(), section #ifdef NEW_INIT_SEQ.
