2012-05-23net: Fix remaining API interface breakageJoe Hershberger
These are all the files which use the API incorrectly but did not get built using MAKEALL -a powerpc|arm. I have no compiler for them, but the remaining issues should be far less than without this patch. Any outstanding issues are left to the maintainers of boards that use these drivers.

2012-03-28Enable high speed support for USB device framework and usbttyVipin KUMAR
This patch adds the support for high speed in usb device framework and usbtty driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board configuration files have to define this macro to enable high speed support. Along with that specific peripheral drivers also need to define a function to let the framework know that the enumeration has happened at high speed. This function prototype is "int is_usbd_high_speed(void)" Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com>

2011-12-16USB: Use (get|put)_unaligned for accessing wMaxPacketSizeTom Rini
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.

2011-02-19USB-CDC: handle interrupt after dropped pullupVitaly Kuzmichev
Disconnecting USB gadget with pending interrupt may cause its wrong handling in the next time when interface will be started again (especially actual for RNDIS). This interrupt may force the gadget to queue unexpected response before setup stage. Despite the fact that such interrupt handled after dropped pullup also may add pending response, this will not bring to any issues due to usb_ep_disable (which clears the queue) called on gadget unregistering.

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
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>

2010-10-13USB-CDC: Prevent rx_req being enqueued twiceVitaly Kuzmichev
After gadget reinitializaton (after tftp has been done once) packet_received may become equal to 1 due to nuking OUT_EP while disabling it in eth_reset_config. rx_submit called from usb_eth_init queues rx_req first time. But the first call of usb_eth_recv from NetLoop queues rx_req again due to packet_received = 1. The following flow shows the path of functions calls when this happens: net/net.c:NetLoop | +-net/eth.c:eth_init | ether.c:usb_eth_init | | | +-udc_driver:usb_gadget_handle_interrupts | | udc_driver:... | | ether.c:eth_setup | | ether.c:eth_set_config | | ether.c:eth_reset_config | | udc_driver:usb_ep_disable | | udc_driver:nuke | | ether.c:rx_complete | | ether.c: packet_received = 1; | | | +-ether.c:rx_submit | udc_driver:usb_ep_queue --- The first time when rx_req is queued | +-net/eth.c:eth_rx ether.c:usb_eth_recv | +-udc_driver:usb_gadget_handle_interrupts | udc_driver:... --- no interrupts, returning +-ether.c: if (packet_received) { ... ether.c:rx_submit udc_driver:usb_ep_queue --- The second time!
