* USB: Use (get|put)_unaligned for accessing wMaxPacketSizeTom Rini2011-12-161-8/+19
| | | | | | | | | | | | | | | | | | | | | | In 9792987721c7980453fe6447c3fa6593b44f8458 Stefan describes a usecase where the previous behavior of leaving wMaxPacketSize be unaligned caused fatal problems. The initial fix for this problem was incomplete however as it showed another cases of non-aligned access that previously worked implicitly. This switches to making sure that all access of wMaxPacketSize are done via (get|put)_unaligned. In order to maintain a level of readability to the code in some cases we now use a variable for the value of wMaxPacketSize and in others, a macro.

* GCC4.6: Fix common/usb.c on xscaleMarek Vasut2011-11-151-4/+9
| | | | | | | | | | The problem was that the code, when the function was compiled with -Os, was misgenerated. As in the function description, this is likely another manifestation of the bug in GCC.

* Revert "GCC4.6: Convert various empty macros to inline functions"Wolfgang Denk2011-10-041-2/+2
| | | | | | | | | | | | This reverts commit 60ce53cf9f408d9ad721f8e7a87d6a564e6d5bac. The commit causes build breakage for a number of boards. This results from the fact that now the arguments of debug() actually get referenced (even if there is hope that the compiler will optimize away the debug() call). The obvious fix to that probem (change the code to always declare the referenced variables and data structures) increases the code size, and was this rejected. So it was decided to revert this commit until a better solution is found.

* USB: Change the necessary defines to get debug outputAlexander Holler2011-02-051-3/+4
| | | | | | | | | | | While debugging some USB stuff, I've first missed that there are actually two defines necessary to get usefull output. The one needed to get debug output for the communication with HUBs was burried somewhere deep inside the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* fix USB initialisation procedureRemy Bohmer2008-10-141-28/+28
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* USB layer of U-Boot causes USB protocol errors while using USB memory sticksRemy Bohmer2008-09-171-20/+30
| | | | | | | | | | | | | | | | | | There are several differences between Linux, Windows and U-boot for initialising the USB devices. While analysing the behaviour of U-boot it turned out that U-boot does things really different, and some are wrong (compared to the USB standard). This patch fixes some errors: * The NEW_init procedure that was already in the code is good, while the old procedure is wrong. See code comments for more info. * On a Control request the data returned by the device can be more than 8 bytes, while the host limits it to 8 bytes. This caused the host to generate a DataOverrun error. This results in a lot of USB sticks not being recognised, and the transmission ended frequently with a CTL:TIMEOUT Error. * Added a flag CONFIG_LEGACY_USB_INIT_SEQ to allow users to use the old init procedure.

* Fix for USB sticks not working on ARM while using GCC 4.x compilersRemy Bohmer2008-09-171-27/+46
| | | | | | | | | | | | | | | | | | | | | | | The GCC-compiler makes an optimisation error while optimising the routine usb_set_maxpacket(). This should be fixed in the compiler in the first place, but there lots of compilers out there that makes this error, that it is probably wiser to workaround it in U-boot itself. What happens is that the register r3 is used as loop-counter 'i', but gets overwritten later on. From there it starts using register r3 for several other things and the assembler code is becoming a big mess. This is clearly a compiler bug. This error occurs on at least several versions of Code Sourcery Lite compilers for ARM. Like the Edition 2008q1, and 2008q3, It has also been seen on other compilers, while compiling for armv4t, or armv5te with Os, O1 and O2. We work around it by splitting up this routine in 2 parts, and making sure that the split out part is NOT inlined any longer. This will make GCC spit out assembler that do not show this problem. Another possibility is to adapt the Makefile to stop optimisation for the complete file. I think this solution is nicer.

* Make usb-stop() safe to call multiple times in a row.Remy Bohmer2008-09-091-4/+9
| | | | | | | | | | | | | | | | | | | | | | | A recent commit (936897d4d1365452bbbdf8430db5e7769ef08d38) enabled the usb_stop() command in common/cmd_bootm.c which was not enabled for some time, because no board did actually set the CFG_CMD_USB flag. So, now the usb_stop() is executed before loading the linux kernel. However, the usb_ohci driver hangs up (at least on AT91SAM) if the driver is stopped twice (e.g. the peripheral clock is stopped on AT91). If some other piece of code calls usb_stop() before the bootm command, this command will hangup the system during boot. (usb start and stop is typically used while booting from usb memory stick) But, stopping the usb stack twice is useless anyway, and a flag already existed that kept track on the usb_init()/usb_stop() calls. So, we now check if the usb stack is really started before we stop it. This problem is now fixed in both the upper as low-level layer.
