buildroot-novena/toolchain, branch 2012.11_rc1

Deprecate the support for the toolchain on target

2012-11-17T08:21:30Z

As discussed during the ELCE 2012 Buildroot Developers Meeting, we no longer want to support the possibility of building a toolchain for the target. None of the core developers have any use for this, it has been known to be broken or cause problems for a long time without anyone providing fixes for it. In addition to this, Buildroot is inherently a cross-compilation tool, so the usage of a native toolchain on the target is not really useful. Many newcomers are tempted to use this possibility even though it is clearly not the intended usage of Buildroot. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

toolchain/gdb: disable support of full gdb on target for blackfin

2012-11-15T23:28:40Z

There is no support in gdb 6.6 for the Blackfin architecture, so disallow this choice. This fixes the following build failure: http://autobuild.buildroot.org/results/e37db29810265a756833da163fda444d967d7874/build-end.log Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

xtensa: support configurable processor configurations

2012-11-15T15:39:48Z

Xtensa is a configurable processor architecture, which allows to define additional instructions and registers. The required variant specific information for the toolchain is delivered in an 'overlay' file, which needs to be 'untarred' to the corresponding directories after the source is installed and patched. This patch provides support for binutils, gcc, and gdb with a very limited changes to the build scripts. These additions are only executed for the Xtensa architecture and have no effect on other architectures. [Thomas: rebased on top of the 'arch: improve definition of gcc mtune, mcpu, etc.' patch, and changed 'Target ABI' to 'Target Architecture Variant'].

xtensa: add support for the Xtensa architecture

2012-11-15T15:39:43Z

The Xtensa architecture had been removed because it required special handling and depended on additional directories and files that became obsolete over time. This change is more aligned to other architectures. [Thomas: rebased on top of the "arch: improve definition of gcc mtune, mcpu, etc." patch].

uClibc: remove useless linuxthreads-errno-fix patch

2012-11-15T15:12:49Z

This patch has since a long time been merged upstream in uClibc, so it cannot apply on any of the recent uClibc snapshots. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard
