* ums: allow the user to specify the device typeStephen Warren2014-05-081-4/+10
| | | | | | | | | | Allow an optional devtype parameter to the ums command, which specifies the type of the device to be exported. This could allow exporting a SATA or even another USB device.

* ums: move all variable declarations to the start of the blockStephen Warren2014-05-081-8/+16
| | | | | | | | | It's easier to assign values to the variables inside an if statement body if the assignment and declaration are separate. Cc: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
* ums: use get_device() not find_mmc_device();Stephen Warren2014-05-081-11/+14
| | | | | | | | | | get_device() is a generic routine that will support any type of block device. Use this instead of the type-specific find_mmc_device(), for future flexibility.

* ums: move IO support code to common locationStephen Warren2014-05-081-0/+46
| | | | | | | | | | There's nothing Samsung-/board-specfic about the implementation of ums_init(). Move the code into cmd_usb_mass_storage.c, so that it can be shared by any user of that command.

* usb: ums: add error handling for failed registrationStephen Warren2014-05-081-1/+5
| | | | | | | | Without this, if g_dnl_register() fails, the UMS code continues on blindly and crashes. This fix makes it simply print an error message instead. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* USB: gadget: added a saner gadget downloader registration APIMateusz Zalega2014-05-051-1/+1
| | | | | | | | | | Preprocessor definitions and hardcoded implementation selection in g_dnl core were replaced by a linker list made of (usb_function_name, bind_callback) pairs.

* usb: dfu: fix boards wo USB cable detectionMateusz Zalega2014-05-051-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | Former usb_cable_connected() patch broke compilation of boards which do not support this feature. I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added its default implementation to gadget downloader driver code. There's only one driver of this kind and it's unlikely there'll be another, so there's no point in keeping it in /common. Previously this function was declared in usb.h. I've moved it, since it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended for USB host implementation. Existing code, confronted with default -EOPNOTSUPP return value, continues as if the cable was connected. CONFIG_USB_CABLE_CHECK was removed.

* usb: ums: wait for usb cable connection before enter ums modePrzemyslaw Marczak2014-01-131-0/+24
| | | | | | | | Before this change ums mode can not be entered when device was using the same usb port for usb/uart communication. Switching USB cable from UART to USB always causes ums exit. Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com>
* usb: ums: add ums exit feature by ctrl+c or by detach usb cablePrzemyslaw Marczak2013-11-081-8/+13
| | | | | | | | | | | | | | | This patch allows exiting from UMS mode to u-boot prompt by detaching usb cable or by pressing ctrl+c. Add new config: CONFIG_USB_CABLE_CHECK. If defined then board file should provide function: usb_cable_connected() (include/usb.h) that return 1 if cable is connected and 0 otherwise. Changes v2: - add a note to the README Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Marek Vasut <marex@denx.de>
* usb: ums: allows using every mmc device with ums.Przemyslaw Marczak2013-11-081-10/+5
| | | | | | | | | | | | | Before this change ums command only allowed use of mmc 0. Now this argument can be set. Changes: - remove mmc device number checking because it is always positive number - remove printing "no such device" - it is done by find_mmc_device() Change-Id: I767e45151ad515c7bef19e6c13087374f5e23c11 Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Marek Vasut <marex@denx.de>
* usb: ums: code refactoring to improve reusability on other boards.Przemyslaw Marczak2013-11-081-16/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces some cleanups to ums code. Changes: ums common: - introduce UMS_START_SECTOR and UMS_NUM_SECTORS as defined in usb_mass_storage.h both default values as 0 if board config doesn't define them common cleanup changes: - change name of struct "ums_board_info" to "ums" - "ums_device" fields are moved to struct ums and "dev_num" is removed - change function name: board_ums_init to ums_init - remove "extern" prefixes from usb_mass_storage.h cmd_usb_mass_storage: - change error() to printf() if need to print info message - change return values to command_ret_t type at ums command code - add command usage string Changes v2: ums common: - always returns number of read/write sectors - coding style clean-up ums gadget: - calculate amount of read/write from device returned value.

* usb: new board-specific USB init interfaceMateusz Zalega2013-10-201-21/+23
| | | | | | | | | | | | | | This commit unifies board-specific USB initialization implementations under one symbol (usb_board_init), declaration of which is available in usb.h. New API allows selective initialization of USB controllers whenever needed.
