* ehci-hcd: Allow cleanups to happen gracefully on a timeout.Joel Fernandes2011-09-04-1/+0
| | | | | | | | | | | | With this, the EHCI seems to "recover" from a timeout. This is particularly observable if you were to ping the wrong IP Address and then ping the correct one or if there was a temporary failure during tftp sessions. All it takes is one timeout to disable it. If you have a noisy network (lot of traffic), even if the traffic is not for the board, the timeouts don't occur.

* USB: Remove __attribute__ ((packed)) for struct ehci_hccr and ehci_hcorJason Kridner2011-09-04-2/+2
| | | | | | | | | | | | | | | | | | | | Remove __attribute__ ((packed)) to prevent byte access to soc registers in some gcc versions. Having patches to enable ehci for the BeagleBoard lying around for several months, this one was the show-stopper. Switched to align(4), rather than remove the attribute, per suggestion from Alexander. Credits have to go to Laine Walker-Avina <lwalkera@ieee.org> for finding the problem.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* ehci-hcd.c: fix hanging under higher loadWolfgang Denk2010-10-22-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch solves a problem with USB hanging under higher load on a i.MX31 board. It falls into class of typical USB problems and fixes: if you don't understand the real cause, add a delay somewhere. The problem appeared after introduction of ELF relocation, which results in smaller code, which appears to run faster (probably because it fits better in the cache); turning off the instruction cache, adding debug printf()s and increasing the delay have all been found to make the problem go away. Moving the original "udelay(1)" up in the code to it's new place made the problem appear much less frequently. Increasing the delay to 2 microseconds then made the code run reliably in all (hour-long) tests. To be on the safe side, we set it to 5 microseconds here.

| | | | | | | | | | | | | | | | Commit 3ed1607 "USB: sync Queue Element Transfer Descriptor against EHCI spec" added an "__attribute__ ((aligned (32)))" to the declaration of struct qTD, as used for example in the Linux kernel as well. However, it turns out that this attribute causes errors in "usb start" (like "ERROR: NOT USB_CONFIG_DESC 7b" and similar). Drop the attribute again.

| | | | | | | | | | | | | | | | | | | Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host Controller Interface Specification for Universal Serial Bus" (Rev. 1.0, March 12, 2002) defines additional fields which were missing in U-Boot's struct qTD; as these are also present in recent versions of struct ehci_qtd in the Linux kernel, we add them here, too. This fixes some nasty memory corruption problems.

* EHCI: zero out QH transfer overlay in ehci_submit_async()Sergei Shtylyov2010-06-29-2/+1
| | | | | | | | | | | | | | | | | | | | | ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI specification suggests) which leads to the controller seeing the "token" field as the previous call has left it, i.e.: - if a timeout occured on the previous call (Active bit left as 1), controller incorrectly tries to complete a previous transaction on a newly programmed endpoint; - if a halt occured on the previous call (Halted bit set to 1), controller just ignores the newly programmed TD(s) and the function then keeps returning error ad infinitum. This turned out to be caused by the wrong orger of the arguments to the memset() call in ehci_alloc(), so the allocated TDs weren't cleared either. While at it, stop needlessly initializing the alternate next TD pointer in the QH transfer overlay... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Acked-by: Remy Bohmer <linux@bohmer.net>

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'.
