      dfu: ram support · a9479f04
      Afzal Mohammed 提交于
      DFU spec mentions it as a method to upgrade firmware (software stored
      in writable non-volatile memory). It also says other potential uses of
      DFU is beyond scope of the spec.
      
      Here such a beyond the scope use is being attempted - directly pumping
      binary images from host via USB to RAM. This facility is a developer
      centric one in that it gives advantage over upgrading non-volatile
      memory for testing new images every time during development and/or
      testing.
      
      Directly putting image onto RAM would speed up upgrade process. This and
      convenience was the initial thoughts that led to doing this, speed
      improvement over MMC was only 1 second though - 6 sec on RAM as opposed
      to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing
      DFU framework to avoid multiple copy for ram (if worth) may help, and
      on other platforms and other boot media like NAND maybe improvement
      would be higher.
      
      And for a platform that doesn't yet have proper DFU suppport for
      non-volatile media's, DFU to RAM can be used.
      
      Another minor advantage would be to increase life of mmc/nand as it
      would be less used during development/testing.
      
      usage: <image name> ram <start address> <size>
      eg. kernel ram 0x81000000 0x1000000
      
      Downloading images to RAM using DFU is not something new, this is
      acheived in openmoko also.
      
      DFU on RAM can be used for extracting RAM contents to host using dfu
      upload. Perhaps this can be extended to io for squeezing out register
      dump through usb, if it is worth.

      RFC: bootm: Add silent_linux environment variable · 8d51aacd
      Simon Glass 提交于
      At present the console for linux is silent if the U-Boot console is silent,
      unless CONFIG_SILENT_U_BOOT_ONLY is set. I wonder if a better way would be
      to have an environment variable to control this? Then we can control the
      verbosity from scripts, and set the variable to 'no' for those boards that
      want Linux to boot with console output.

      Licenses: introduce SPDX Unique Lincense Identifiers · eca3aeb3
      Wolfgang Denk 提交于
      Like many other projects, U-Boot has a tradition of including big
      blocks of License headers in all files.  This not only blows up the
      source code with mostly redundant information, but also makes it very
      difficult to generate License Clearing Reports.  An additional problem
      is that even the same lincenses are referred to by a number of
      slightly varying text blocks (full, abbreviated, different
      indentation, line wrapping and/or white space, with obsolete address
      information, ...) which makes automatic processing a nightmare.
      
      To make this easier, such license headers in the source files will be
      replaced with a single line reference to Unique Lincense Identifiers
      as defined by the Linux Foundation's SPDX project [1].  For example,
      in a source file the full "GPL v2.0 or later" header text will be
      replaced by a single line:
      
              SPDX-License-Identifier:        GPL-2.0+
      
      We use the SPDX Unique Lincense Identifiers here; these are available
      at [2].
      
      Note: From the legal point of view, this patch is supposed to be only
      a change to the textual representation of the license information,
      but in no way any change to the actual license terms. With this patch
      applied, all files will still be licensed under the same terms they
      were before.
      
      Note 2: The apparent difference between the old "COPYING" and the new
      "Licenses/gpl-2.0.txt" only results from switching to the upstream
      version of the license which is differently formatted; there are not
      any actual changes to the content.
      
      Note 3: There are some recurring questions about linense issues, such
      as:
          - Is a "All Rights Reserved" clause a problem in GPL code?
          - Are files without any license header a problem?
          - Do we need license headers at all?
      
      The following excerpt from an e-mail by Daniel B. Ravicher should help
      with these:

      | That is a very fact specific analysis and could be different across the

      | If the project as a whole is licensed under clear terms, you need not
      | identify those same terms in each file, although there is no harm in

      | It is not a conflict to grant a license and also reserve all rights, as
      | implicit in that language is that you are reserving all "other" rights
      | not granted in the license.  Thus, a file with "Licensed under GPL, All
      | Rights Reserved" would mean that it is licensed under the GPL, but no
      | other rights are given to copy, modify or redistribute it.
