* IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic2011-04-27-1/+1
| | | | | | | | | | As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.

* Fix EHCI usb submit timeout and unify with OHCISimon Glass2011-02-19-7/+10
| | | | | | | | | | | | 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.

* usb: Remove usb_dev_init() from ehci-ppc4xx.cStefan Roese2010-11-26-1/+0

* usb: Clear CMD_RUN while issuing CMD_RESET in ehci_reset()Stefan Roese2010-11-26-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem noticed on lwmon5 (PPC440EPx) using the common EHCI driver, when "usb reset" is issued multiple times. Upon the 2nd (and further) "usb reset" command, the command fails with the following messages: => usb reset (Re)start USB... USB: Register 1111 NbrPorts 1 USB EHCI 1.00 scanning bus for devices... 5 USB Device(s) found scanning bus for storage devices... 2 Storage Device(s) found => usb reset (Re)start USB...

* usb: fix for USB_ST_STALLED status reporting in ehci_submit_async()Anatolij Gustschin2010-11-26-0/+2
| | | | | | | | | | | Checking the status field of the qTD token in the current code do not take into acount cases where endpoint stall (halted) bit is set together with XactErr status bit. As a result clearing stall on an endpoint won't be done if this status bit was also set. Check for halted bit and report USB_ST_STALLED status if the host controller also indicates endpoit stall condition. Signed-off-by: Anatolij Gustschin <agust@denx.de>
* 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.

* USB: fix Queue Element Transfer Descriptor changesWolfgang Denk2010-10-22-1/+1
| | | | | | | | | | | | | | | | 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.

* USB: sync Queue Element Transfer Descriptor against EHCI specWolfgang Denk2010-10-20-5/+10
| | | | | | | | | | | | | | | | | | | 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'. 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.
