* usb: do explicit unaligned accessesLucas Stach2012-09-21-5/+9
| | | | | | | | | | | | | | | usb_hub_descriptor has to be packed as it's used for communication with the device. Member wHubCharacteristics violates the natural alignment rules. Use explicit unaligned access functions for this member. Fixes ARMv7 traping while using USB. v2: fix typo found by Thomas Langer v3: rebased on top of u-boot-usb/master Signed-off-by: Lucas Stach <dev@lynxeye.de>
* USB: Align buffers at cachelinePuneet Saxena2012-05-20-13/+14
| | | | | | | | | | | | 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.

* usb: replace wait_ms() with mdelay()Mike Frysinger2012-03-19-5/+5
| | | | | | | | | | | | | | | | | | | | | | | 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>
* USB: relax usbcore reset timingsWolfgang Grandegger2012-03-03-1/+4
| | | | | | | | | | | | Following the corresponding Linux code, this patch relaxes reset timings waiting at least 100ms after power to the ports. There are some reports that it helps make enumeration work better on some high speed devices. Furthermore, the wait is only done once after power has been enabled on all ports.
