Hello all,
U-Boot v2010.09 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 commits we pulled from the next branch into mainline contain 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=u-boot.git;a=commit;h=ea882baf
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.
This allows to efficiently use the same U-Bot 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 especailly interesting now that ARM is getting
Device Tree support as well.
Please note that *all* ARM boards need to be adapted to this noew
code, which requires testing on the actual hardware, so this is a
task for the respective board maintainers or other users.
*****************************************************************
* Currently, most ARM boards are *broken* and *do not compile*. *
*****************************************************************
Please see the commit message of commit f1d2b31 for details:
http://git.denx.de/?p=u-boot.git;a=commit;h=f1d2b31
Support for CONFIG_SYS_ARM_WITHOUT_RELOC will be removed after
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 for the community and will be removed as well.
