| * USB i.MX: Add chipidea gadget supportSascha Hauer2013-02-151-2/+9
| | | | | | | | | | | | | | | | This adds USB gadget support to the i.MX chipidea driver. Basically we have to add a register function to the fsl udc driver and call this from the chipidea driver if device mode is selected. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* introduce console none supportJean-Christophe PLAGNIOL-VILLARD2013-01-231-1/+1
| | | | | | | | | | | | this will allow to have no console support Use full for bootstrap as we can save 6.5 KiB (barebox.bin) and 3.8 KiB (zbarebox.bin lzo) on at91sam9263 as example vs console simple As on bootstrap we have often very limited size.

* usb: add flow control to u_serialRobert Jarzmik2012-10-291-8/+17
| | | | | | | | | | | | | | | | | | | When using the serial console over USB to download files, and when the USB bandwidth is pushed to its limits, the barebox UDC device won't be able to absorb all the traffic. Modify the u_serial gadget so that if there is not enough room in buffers, don't push USB requests down the gadget driver, so that it is saturated, and give it a chance to NAK requests. The previous behaviour was loosing bytes (as kfifo_put is lossy). The fixed behavious is lossless (based on USB NAK protocol). While at it, increase a bit buffer sizes to 8kB to absorb heavy transfers such as a linux kernel image.

* usb/gadget: fix poller NPE in early pollingRobert Jarzmik2012-01-231-9/+10
| | | | | | | | | | | | | The timings of the poller calling have changed, digging out a latent bug in pxa27x udc controller. The polling routine is called before the probe function is called, and the driver internal are not initialized at that time. This triggers a NULL pointer exception.

* dfu: fill bwPollTimeout and better handle detachEric Bénard2012-01-041-1/+8
| | | | | | | | | | | | | | | | | - bwPollTimeout is set to 10 ms, from the DFU spec, this is the minimum time, in milliseconds, that the host should wait before sending a subsequent DFU_GETSTATUS request. Without this, I get 25 seconds value and dfu-util waits twice 25s during download - when in IDLE and receiving DETACH, first return 0 to make dfu-util happy, then use a dfudetach variable to exit dfu (without an USB reset as per the comment on line 425) and return to runtime mode. - tested on i.MX25 & i.MX35 & usb-a926x Signed-off-by: Eric Bénard <eric@eukrea.com> Tested-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* usb/gadget: make serial gadget resistant to cable unplugRobert Jarzmik2011-12-051-6/+18
| | | | | | | | | | | | | | As USB can have its cable plugged out anytime, make the serial gadget reliable in case of unplugging : - unregister the gadget_serial provided console - don't stay forever in the read loop if connection was cut This behaviour relies on correct implementation of usb_gadget_poll(), which should return an error if the USB cable was removed.

* Fix error handling with malloc, memalign etc. Introduce xmemalign().Krzysztof Halasa2011-01-073-11/+2
| | | | | | | | | | | | | | The idea is to panic() when there is no memory available for normal operation. Exception: code which can consume arbitrary amount of RAM (example: files allocated in ramfs) must report error instead of panic(). This patch also fixes code which didn't check for NULL from malloc() etc. Usage: malloc(), memalign() return NULL when out of RAM. xmalloc(), xmemalign() always return non-NULL or panic().
