xtensa: Add -mforce-no-pic option is supported

2010-05-02T08:00:22+00:00

GCC is configured to always compile with PIC enabled for the Xtensa
architecture. This fails when nfsroot is enabled as the code uses a
non-conformant segment that mismatches in permissione with a read-only
segment.
A patch has been submitted to GCC to add the machine-option 'force-no-pic'
that disables PIC.

xtensa: only build platform or variant if they contain a Makefile

2009-04-03T07:06:45+00:00

We only add the platform or variant directory to core-y if it
contains a Makefile. Consequently, we can remove the Makefiles
for the dc232b and fsf processor variants.

xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09+00:00

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.

Moving the files gets also rid of all uses of symlinks in the Makefile.

This has been completed already for the majority of the architectures
and xtensa is one out of six missing.

kbuild: enable 'make CFLAGS=...' to add additional options to CC

2007-10-14T20:21:35+00:00

The variable CFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.

This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
tree and enabling one to use:
make CFLAGS=...
to specify additional gcc commandline options.

One usecase is when trying to find gcc bugs but other
use cases has been requested too.

Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k

Test was simple to do a defconfig build, apply the patch and check
that nothing got rebuild.
