  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.

• 0697f206d   usb: ums: fix disk capacity miscalculation and code cleanup ... Browse Code »

  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

• 93c813b3a   usb: ums: code refactoring to improve reusability on other boards. ... Browse Code »

  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.h.

  New API allows selective initialization of USB controllers whenever needed.

• ba4e95c9f   usb:g_dnl:ums: Conditional compilation for mass storage function (f_mass_storage) ... Browse Code »

  The mass storage composite function is now compiled in only when
  CONFIG_USB_GADGET_MASS_STORAGE is defined.
  Such change provides binary size reduction for boards which use USB
  download gadget (like am335x_evm) with DFU, but don't use UMS.

  For example at am335x_evm board reduction is more than 2KiB for
  text and around 120B for data.
