SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

dm: Drop the block_dev_desc_t typedef

2016-03-14T21:34:50Z

Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long and causes 80-column violations, rename it to struct blk_desc. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Stephen Warren

ums: support multiple LUNs at once

2016-01-14T02:05:19Z

Extend the ums command to accept a list of block devices. Each of these will be exported as a separate LUN. An example use-case would be: ums 0 mmc 0,0.1,0.2 ... which would export LUNs for eMMC 0's user data, boot0, and boot1 HW partitions. This is useful since it allows the host access to everything on the eMMC without having to somehow stop the ums command from executing and restart it with different parameters.

ums: move IO support code to common location

2014-05-08T08:38:29Z

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. Cc: Lukasz Majewski Signed-off-by: Stephen Warren Acked-by: Przemyslaw Marczak

ums: remove UMS_{NUM,START}_SECTORS + UMS_START_SECTOR

2014-05-08T08:38:29Z

These values aren't set anywhere at present, and hence have no effect. The concept of a single global offset/number of sectors to expose through USB Mass Storage doesn't even make sense in the face of multiple storage devices. Remove these defines to simplify the code.

ums: support block devices not MMC devices

2014-05-08T08:38:29Z

The USB Mass Storage function could equally well support a SATA device as support an MMC device. Update struct ums to contain a block device descriptor, not an MMC device descriptor. Cc: Lukasz Majewski Signed-off-by: Stephen Warren Acked-by: Przemyslaw Marczak

USB: gadget: added a saner gadget downloader registration API

Preprocessor definitions and hardcoded implementation selection in g_dnl core were replaced by a linker list made of (usb_function_name, bind_callback) pairs. Signed-off-by: Mateusz Zalega Acked-by: Lukasz Majewski Acked-by: Marek Vasut

usb: ums: wait for usb cable connection before enter ums mode

2014-01-13T11:29:12Z

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

usb: ums: fix disk capacity miscalculation and code cleanup

2013-11-08T19:46:19Z

This patch prevents: - ums disk capacity miscalculation because of integer overflow Changes v2: - Prevents passing zero size disk capacity to ums gadget driver - Change function ums_get_capacity() to ums_disk_init() and do ums disk initialization before gadget init - Remove unnecessary code from mass storage driver Signed-off-by: Przemyslaw Marczak Cc: Marek Vasut

usb: ums: code refactoring to improve reusability on other boards.

2013-11-08T19:46:19Z

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.
