[Buildroot] [PATCH 1/5] arch: improve definition of gcc mtune, mcpu, etc.

[Thomas Petazzoni]

As suggested by Yann E. Morin, there is a better way than our current
big Config.in.common to define the gcc mtune, mcpu, march,
etc. values. We can split the setting of those values in each
architecture file, which makes a lot more sense.

Therefore, the Config.in file now creates empty kconfig variables
BR2_ARCH, BR2_ENDIAN, BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH,
BR2_GCC_TARGET_ABI and BR2_GCC_TARGET_CPU. The values of those
variables are set by the individual Config.in.<arch> files. This is
possible because such files are now only conditionally included
depending on the top-level architecture that has been selected.

[Buildroot] [PATCH 2/5] uClibc: remove useless linuxthreads-errno-fix patch

[Thomas Petazzoni]

This patch has since a long time been merged upstream in uClibc, so it
cannot apply on any of the recent uClibc snapshots.

-From: Peter Korsgaard <jacmet@sunsite.dk>
-Date: Mon, 5 Jul 2010 14:08:17 +0200
-Subject: [PATCH] don't make __errno_location / __h_errno_location hidden
-
-Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089)
-
-__errno_location / __h_errno_location access has to go through the PLT
-like malloc/free, so the linuxthread variants gets used instead when
-compiling with -pthread.
-
-Based on http://github.com/mat-c/uClibc/commit/328d392c54aa5dc2b8e7f398a419087de497de2b

[Buildroot] [PATCH 4/5] xtensa: add support for the Xtensa architecture

[Thomas Petazzoni]

From: Chris Zankel <chris@zankel.net>

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].

[Buildroot] [PATCH 5/5] xtensa: support configurable processor configurations

[Thomas Petazzoni]

From: Chris Zankel <chris@zankel.net>

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'].

I know you are just moving stuff around, but those symbols are typed
as strings, so the default values should be enclosed in-between double
quotes:
    default "arm600"   if BR2_arm600

Moreover, the code is not coherent with itslef, even in a single file.
For example, you have (both are string symbols):

    config BR2_ENDIAN
        default "LITTLE" if BR2_arm

    config BR2_GCC_TARGET_TUNE
        default arm600   if BR2_arm600

That it currently works is just happenstance, and may well break in
the future when we upgrade to a newer kconfig version.

Maybe we can just apply this for now, and fix that in a future patch?
