2012-05-20USB: Align buffers at cachelinePuneet Saxena
This avoids cache-alignment warnings shown in console when a usb command is entered. Whenever X bytes of unaligned buffer is invalidated, arm core invalidates X + Y bytes as per the cache line size and throws these warnings.

2012-03-19usb: replace wait_ms() with mdelay()Mike Frysinger
Common code has a mdelay() func, so use that instead of the usb-specific wait_ms() func. This also fixes the build errors: ohci-hcd.c: In function 'submit_common_msg': /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1519:9: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1816:10: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1827:10: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1844:10: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1563:11: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1583:9: sorry, unimplemented: called from here make[1]: *** [ohci-hcd.o] Error 1 Signed-off-by: Mike Frysinger <vapier@gentoo.org> Acked-by: Marek Vasut <marex@denx.de>

2011-08-08usb: increase non-bulk timeout for slow chipsets.Jason Cooper
If you take a look at 96820a35, you'll see the original timeout was CONFIG_SYS_HZ. Which is 1000. After the mentioned change, non-bulk timeout was changed to 100. This causes timeout failures on the dreamplug platform when trying to initialize the usb microsd reader.

This adds support for using USB Ethernet dongles in host mode. This is just the framework - drivers will come later. A new config option called CONFIG_USB_HOST_ETHER can be defined in board config files to switch this on. The was originally written by NVIDIA and was cleaned up for release by the Chromium authors.

2011-02-19Fix EHCI usb submit timeout and unify with OHCISimon Glass
Changed both to use a common timeout for URB submission, since they were using different values and EHCI's was too short. Also fixed EHCI to actually check if urb submission succeeded, rather than silently continuing into the weeds.

2009-12-20USB Consolidate descriptor definitionsTom Rix
The header files usb.h and usbdescriptors.h have the same nameed structure definitions for usb_config_descriptor usb_interface_descriptor usb_endpoint_descriptor usb_device_descriptor usb_string_descriptor These are out right duplicates in usb.h usb_device_descriptor usb_string_descriptor This one has extra unused elements usb_endpoint_descriptor unsigned char bRefresh unsigned char bSynchAddress; These in usb.h have extra elements at the end of the usb 2.0 specified descriptor and are used. usb_config_descriptor usb_interface_descriptor The change is to consolidate the definition of the descriptors to usbdescriptors.h. The dublicates in usb.h are removed. The extra element structure will have their name shorted by removing the '_descriptor' suffix. So usb_config_descriptor -> usb_config usb_interface_descriptor -> usb_interface For these, the common descriptor elements are accessed now by an element 'desc'. As an example - if (iface->bInterfaceClass != USB_CLASS_HUB) + if (iface->desc.bInterfaceClass != USB_CLASS_HUB) This has been compile tested on MAKEALL arm, ppc and mips.

2008-12-09USB: descriptor handlingStefan Althoefer
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).

2008-10-14fix USB initialisation procedureRemy Bohmer
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.

2005-07-21Fix low-level OHCI transfers for ARM920t and MPC5xxxWolfgang Denk
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.
