| * usb: ehci: poll_int_queue check real qtd, not the overlayHans de Goede2014-10-06-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we first start an int queue, the qh's overlay area is all zeros. This gets filled by the hc with the actual qtd values as soon as it advances the queue, but we may call poll_int_queue before then, in which case we would think the transfer has completed as the hc has not yet copied the qt_token to the overlay, so the active flag is not set. This fixes this by checking the actual qtd token, rather then the overlay. This also fixes a (theoretical) race where we see the completion in the overlay and free and re-use the qtd before the hc has completed writing back the overlay to the actual qtd.

| * usb: ehci-mx6: Rename the USB register base addressYe.Li2014-09-29-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The mx6sl/mx6sx has 2 OTG and 1 host. So they have name "USBO2H_USB_BASE_ADDR" in imx-regs.h. The driver hard codes the USB base address name to "USBOH3", which causes the driver failed to build for mx6sl/mx6sx. This patch uniform the address name to "USB_BASE_ADDR" for all mx6 series.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Tested-by: Stephen Warren <swarren@nvidia.com>

* | dfu: allow backend to specify a maximum buffer sizeStephen Warren2014-08-09-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts to transfer large files. However, this means that individual write operations will take a long time. Allow backends to specify a maximum buffer size, so that each write operation is limited to a smaller data block. This prevents the DFU protocol from timing out when e.g. writing to SPI flash. I would guess that NAND might benefit from setting this value too, but I can't test that.

* | dfu: add write error handlingStephen Warren2014-08-09-4/+16
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O itself. This could happen due to problems with the storage medium, or simply when trying to write a FAT/ext file that is larger than the buffer dfu_mmc.c maintains for this purpose. Signal the error by switching the DFU state/status. This will be picked up by the DFU client when it sends the next DFU request. Note that errors can't simply be returned from e.g. dnload_request_complete(), since that function has no way to pass errors back to the DFU client; a call to dnload_request_complete() simply means that a USB OUT completed. This error state/status needs to be cleared when the next DFU client connects. While there is a DFU_CLRSTATUS request, no DFU client seems to send this. Hence, clear this when selecting the USB alternate setting on the USB interface. Finally, dfu.c relies on a call to dfu_flush() to clear up the internal state of the write transaction. Now that errors in dfu_write() are detected, dfu_flush() may no longer be called for every transaction. Separate out the cleanup code into a new function, and call it whenever dfu_write() fails, as well as from any call to dfu_flush(). Signed-off-by: Stephen Warren <swarren@nvidia.com>

* USB: gadget: atmel: zero out allocated requestsStephen Warren2014-07-02-1/+1
| | | | | | | | | | | A UDC's alloc_request method should zero out the newly allocated request. Ensure the Atmel driver does so.

| | | | | | | | | | struct ci_req is a purely software structure, and needs no specific memory alignment. Hence, allocate it with calloc() rather than memalign().

* usb: ci_udc: remove controller.items arrayStephen Warren2014-07-02-6/+3
| | | | | | | | There's no need to store an array of QTD pointers in the controller. Since the calculation is so simple, just have ci_get_qtd() perform it at run-time, rather than pre-calculating everything. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* usb: ci_udc: fix items array size/stride calculationStephen Warren2014-07-02-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | 2 QTDs are allocated for each EP. The current allocation scheme aligns the first QTD in each pair, but simply adds the struct size to calculate the second QTD's address. This will result in a non-cache-aligned addresss IF the system's ARCH_DMA_MINALIGN is not 32 bytes (i.e. the size of struct ept_queue_item). Similarly, the original ilist_ent_sz calculation aligned the value to ARCH_DMA_MINALIGN but didn't take the USB HW's 32-byte alignment requirement into account. This doesn't cause a practical issue unless ARCH_DMA_MINALIGN < 32 (which I suspect is quite unlikely), but we may as well fix the code to be explicit, so it's obviously completely correct. The new value of ILIST_ENT_SZ takes all alignment requirements into account, so we can simplify ci_{flush,invalidate}_qtd() by simply using that macro rather than calling roundup(). Similarly, the calculation of controller.items[i] can be simplified, since each QTD is evenly spaced at its individual alignment requirement, rather than each pair being aligned, and entries within the pair being spaced apart only by structure size.

* usb: ci_udc: lift ilist size calculations to global scopeStephen Warren2014-07-02-14/+14
| | | | | | | | | | | | This will allow functions other than ci_udc_probe() to make use of the constants in a future change. This in turn requires converting the const int variables to #defines, since the initialization of one global const int can't depend on the value of another const int; the compiler thinks it's non-constant if that dependency exists.

* usb: ci_udc: fix ci_flush_{qh,qtd} calls in ci_udc_probe()Stephen Warren2014-07-02-2/+2
| | | | | | | | | | | | | | | ci_udc_probe() initializes a pair of QHs and QTDs for each EP. After each pair has been initialized, the pair is cache-flushed. The conversion from QH/QTD index [0..2*NUM_END_POINTS) to EP index [0..NUM_ENDPOINTS] is incorrect; it simply subtracts 1 (which yields the QH/QTD index of the first entry in the pair) rather than dividing by two (which scales the range). Fix this. On my system, this avoids cache debug prints due to requests to flush unaligned ranges. This is caused because the flush calls happen before the items[] array entries are initialized for all but EP0. Signed-off-by: Stephen Warren <swarren@nvidia.com>

* usb: ci_udc: fix interaction with CONFIG_USB_ETH_CDCStephen Warren2014-06-25-1/+7
| | | | | | | | | | | | | | | | | | | | | | ci_udc.c's usb_gadget_unregister_driver() doesn't call driver->unbind() unlike other USB gadget drivers. Fix it to do this. Without this, when ether.c's CDC Ethernet device is torn down, eth_unbind() is never called, so dev->gadget is never set to NULL. For some reason, usb_eth_halt() is called both at the end of the first use of the Ethernet device, and prior to any subsequent use. Since dev->gadget is never cleared, all calls to usb_eth_halt() attempt to stop, disconnect, and clean up the device, resulting in double cleanup, which hangs U-Boot on my Tegra device at least. ci_udc allocates its own singleton EP0 request object, and cleans it up during usb_gadget_unregister_driver(). This appears necessary when using the USB gadget framework in U-Boot, since that does not allocate/free the EP0 request. However, the CDC Ethernet driver *does* allocate and free its own EP0 requests. Consequently, we must protect ci_ep_free_request() against double-freeing the request.
