Hello all,

U-Boot v2010.12 has been released and is available from the git
repository and the FTP server.

The "next" branch has been pulled into mainline ("master" branch) and
has been removed afterward.



		********************
		********************
		**                **
		**  BIG FAT NOTE  **
		**                **
		********************
		********************

The release contains, among many other things, 3 major groups of
changes:

1) New implementation for internal handling of environment variables.

   In addition to the traditional commands "setenv", "printenv" and
   "saveenv" there is now a new "env" command with a number opf
   subcommands that offer many new features. Please see the commit
   message of commit ea882baf for details:

   http://git.denx.de/?p=3Du-boot.git;a=3Dcommit;h=3Dea882baf

2) ARM cache support.

   This greatly accelerates U-Boot on many ARM systems, especially
   functions like uncompressing images or loading images form external
   storage are now much faster, sometimes by a factor > 10. For
   details please see these commits:

   7e4a9e6 ARM (ARM11): add data cache support, test on Qong board
   95c6f6d ARM V7 (OMAP): add data cache support, test on Beagle board
   c3330e9 ARM (ARM926ejs): add data cache support, tested on magnesium and tx25 board

   http://git.denx.de/?p=u-boot.git;a=commit;h=7e4a9e6
   http://git.denx.de/?p=u-boot.git;a=commit;h=95c6f6d
   http://git.denx.de/?p=u-boot.git;a=commit;h=c3330e9

3) ARM relocation support (ELF relocation)

   This allows to efficiently use the same U-Boot binary image on
   systems with different RAM sizes, and brings the implementation
   much more in line with the code used for example on Power
   Architecture systems (eventually allowing to merge into common
   code). This seems especially interesting now that ARM is getting
   Device Tree support as well.

   Please note that not all ARM boards have been adapted to this new
   code yet, which requires testing on the actual hardware, so this
   is a task for the respective board maintainers or other users.

   *****************************************************************
   * Currently, >100 ARM boards are *broken* and *do not compile*. *
   *****************************************************************

   Board maintainers or othe rinterested parties are requested to
   adapt their boards to the new code in the timeframe of the
   upcoming release v2010.03; all boards that have not been converted
   by then, i. e. that are still broken then, are considered
   unmaintained and without interest to the community and will be
   removed.

--- end of big fat note ---
