xtensa: use uppercase for configurations and modified overlay structure

2012-11-21T10:08:50+00:00

Except for architecture and processor names, buildroot uses capitalized configuration names, so change the macro names for xtensa to follow that standard. Change the overlay file to have a subdirectory for each component (gdb, binutils, gcc, etc.) to make it more future-prove. Signed-off-by: Chris Zankel Signed-off-by: Peter Korsgaard

Deprecate the support for the toolchain on target

2012-11-17T08:21:30+00:00

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

xtensa: support configurable processor configurations

2012-11-15T15:39:48+00:00

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'].

Remove the Xtensa architecture

2012-09-20T20:31:08+00:00

As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the Xtensa architecture has been introduced in 2009 and never changed since its initial introduction. It requires some special handling that is a bit annoying, and despite our call to the initial developers, and the announcement of the deprecation of the architecture during the 2012.05, nothing has happened. Therefore, drop support for this architecture. Signed-off-by: Thomas Petazzoni Acked-by: me Signed-off-by: Peter Korsgaard

Simplify x86 target architecture variant handling

2012-07-30T22:00:29+00:00

Instead of having two separate list of choices for select the target architecture variant for i386 and x86_64, with many CPU choices duplicated (because all modern x86 CPUs can be both used as i386 or x86_64), merge them into a single list. In the x86_64 case, all the x86 CPUs that do not support the 64 bits instruction set are hidden. Signed-off-by: Thomas Petazzoni

Remove REAL_GNU_TARGET_NAME
