2018-06-13lib: Add hexdumpAlexey Brodkin
Often during debugging session it's very interesting to see what data we were dealing with. For example what we write or read to/from memory or peripherals. This change introduces functions that allow to dump binary data with one simple function invocation like: ------------------->8---------------- print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len); ------------------->8---------------- which gives us the following: ------------------->8---------------- 00000000: f2 b7 c9 88 62 61 75 64 72 61 74 65 3d 31 31 35 ....baudrate=115 00000010: 32 30 30 00 62 6f 6f 74 61 72 67 73 3d 63 6f 6e 200.bootargs=con 00000020: 73 6f 6c 65 3d 74 74 79 53 33 2c 31 31 35 32 30 sole=ttyS3,11520 00000030: 30 6e 38 00 62 6f 6f 74 64 65 6c 61 79 3d 33 00 0n8.bootdelay=3. 00000040: 62 6f 6f 74 66 69 6c 65 3d 75 49 6d 61 67 65 00 bootfile=uImage. 00000050: 66 64 74 63 6f 6e 74 72 6f 6c 61 64 64 72 3d 39 fdtcontroladdr=9 00000060: 66 66 62 31 62 61 30 00 6c 6f 61 64 61 64 64 72 ffb1ba0.loadaddr 00000070: 3d 30 78 38 32 30 30 30 30 30 30 00 73 74 64 65 =0x82000000.stde 00000080: 72 72 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 rr=serial0@e0022 00000090: 30 30 30 00 73 74 64 69 6e 3d 73 65 72 69 61 6c 000.stdin=serial 000000a0: 30 40 65 30 30 32 32 30 30 30 00 73 74 64 6f 75 0@e0022000.stdou 000000b0: 74 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 30 t=serial0@e00220 000000c0: 30 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00.............. ... ------------------->8---------------- Source of hexdump.c was copied from Linux kernel v4.7-rc2.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>
2017-11-26usb: gadget: storage: Increase FSG_BUFLENMarek Vasut
Increase the buffer length to be just above maximum permissible value of 128 kiB . This increases the performance of the UMS and alike by a factor of 2 - 2.5 as the buffers are less fragmented. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Lukasz Majewski <lukma@denx.de>
2016-01-13ums: support multiple LUNs at onceStephen Warren
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.

2014-05-07usb: ums: remove ci_udc special caseStephen Warren
Now that the ci_udc driver supports allocating multiple requests per endpoint, we can revert the special-case added by a022c1e13c01 "usb: ums: use only 1 buffer for CI_UDC". Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-04-30usb: ums: use only 1 buffer for CI_UDCStephen Warren
ci_udc.c allocates only a single buffer for each endpoint, which ci_ep_alloc_request() returns as a hard-coded value rather than dynamically allocating. Consequently, storage_common.c must limit itself to using a single buffer at a time. Add a special case to the definition of FSG_NUM_BUFFERS for this. Another option would be to fix ci_ep_alloc_request() to dynamically allocate the buffers like some/all(?) other device mode drivers do. However, I don't think that ci_ep_queue() supports queueing up multiple buffers either yet, and I'm not familiar enough with the controller yet to implement that. As such, any attempt to use multiple buffers simply results in data corruption and other errors. Signed-off-by: Stephen Warren <swarren@nvidia.com>

2013-11-08usb: ums: code refactoring to improve reusability on other boards.Przemyslaw Marczak
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.
