      new commands: uuid and guid - generate random unique identifier · 89c8230d
      Przemyslaw Marczak authored
      Those commands basis on implementation of random UUID generator version 4
      which is described in RFC4122. The same algorithm is used for generation
      both ids but string representation is different as below.
      
      char:  0        9    14   19   24         36
             xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
      UUID:     be     be   be   be       be
      GUID:     le     le   le   be       be
      
      Commands usage:
      - uuid [<varname>]
      - guid [<varname>]
      
      The result is saved in environment as a "varname" variable if argument is given,
      if not then it is printed.
      
      New config:
      - CONFIG_CMD_UUID

      usb: dfu: introduce dfuMANIFEST state · 001a8319
      Heiko Schocher authored
      on nand flash using ubi, after the download of the new image into
      the flash, the "rest" of the nand sectors get erased while flushing
      the medium. With current u-boot version dfu-util may show:
      
      Starting download: [##################################################] finished!
      state(7) = dfuMANIFEST, status(0) = No error condition is present
      unable to read DFU status
      
      as get_status is not answered while erasing sectors, if erasing
      needs some time.
      
      So do the following changes to prevent this:
      
      - introduce dfuManifest state
        According to dfu specification
        ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7:
        "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation
         of the status report by the host. Upon receipt of the anticipated
         DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it
         completes its reprogramming operations."
      
      - when stepping into dfuManifest state, sending a PollTimeout
        DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host
        (dfu-util) waits the PollTimeout before sending a get_status again.

      arm: Switch to -mno-unaligned-access when supported by the compiler · 1551df35
      Tom Rini authored
      When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
      matter) it assumes a default of SCTRL.A being cleared and unaligned
      accesses being allowed and fast at the hardware level.  We set this bit
      and must pass along -mno-unaligned-access so that the compiler will
      still breakdown accesses and not trigger a data abort.
      
      To better help understand the requirements of the project with respect
      to unaligned memory access, the
      Documentation/unaligned-memory-access.txt file has been added as
      doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
      tag of the kernel.

      powerpc/mpc85xx: Add support for single source clocking · b135991a
      Priyanka Jain authored
      Single-source clocking is new feature introduced in T1040.
      In this mode, a single differential clock is supplied to the
      DIFF_SYSCLK_P/N inputs to the processor, which in turn is
      used to supply clocks to the sysclock, ddrclock and usbclock.
      
      So, both ddrclock and syclock are driven by same differential
      sysclock in single-source clocking mode whereas in normal clocking
      mode, generally separate DDRCLK and SYSCLK pins provides
      reference clock for sysclock and ddrclock
      
      DDR_REFCLK_SEL rcw bit is used to determine DDR clock source
      -If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in
       normal clocking mode by DDR_Reference clock
      
      -If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in
       single source clocking mode by DIFF_SYSCLK
      
      Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

      Add dumpimage, a tool to extract data from U-Boot images · a804b5ce
      Guilherme Maciel Ferreira authored
      Given a multi-file image created through the mkimage's -d option:
      
        $ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
        multi.img
      
        Image Name:   x86
        Created:      Thu Jul 25 10:29:13 2013
        Image Type:   Intel x86 Linux Multi-File Image (gzip compressed)
        Data Size:    13722956 Bytes = 13401.32 kB = 13.09 MB
        Load Address: 00000000
        Entry Point:  00000000
        Contents:
           Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
           Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
           Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB
      
      It is possible to perform the innverse operation -- extracting any file from
      the image -- by using the dumpimage's -i option:
      
        $ dumpimage -i multi.img -p 2 System.map
      
      Although it's feasible to retrieve "data files" from image through scripting,
      the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
      is cumbersome and unreliable -- once you must keep track of file sizes inside
      the image. Furthermore, extracting data files using "dumpimage" tool is faster
      than through scripting.

      arm, am33x: make RTC32K OSC enable configurable · 16678eb4

      states:
      "Initialize devices only when they are needed within U-Boot"
      
      enable the RTC32K OSC only, if CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC is
      enabled. Enable this in ti_am335x_common.h, so all boards in mainline
      should work as before.

      bootcount: store bootcount var in environment · eda0ba38
      Heiko Schocher authored
      If no softreset save registers are found on the hardware
      "bootcount" is stored in the environment. To prevent a
      saveenv on all reboots, the environment variable
      "upgrade_available" is introduced. If "upgrade_available" is
      0, "bootcount" is always 0 therefore no need to save the
      environment on u-boot boot, if "upgrade_available" is 1 "bootcount"
      is incremented in the environment and environment gets written
      on u-boot start.
      So the Userspace Applikation must set the "upgrade_available"
      and "bootcount" variable to 0 (for example with fw_setenv),
      if a boot was successfully.

      file should provide function: usb_cable_connected() (include/usb.h)
      that return 1 if cable is connected and 0 otherwise.

      env exists is a way to test (in hush) if an environment variable

      doesn't require all the stdout/stderr redirection to prevent
      printing information to the screen.
      
      Example:
      $ set testexists 1
      $ env exists testexists && echo "yes"
      yes
      $ env exists testexists || echo "no"
      $ set testexists
      $ env exists testexists && echo "yes"
      $ env exists testexists || echo "no"
      no
