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.

[XTENSA] Fix makefile to work with binutils-2.18.

2008-02-14T01:45:05+00:00

When building with binutils-2.18, vmlinux includes .note.gnu.build-id
sections that need to be stripped out when building the binary image.
The old .xt.insn sections haven't been used for a long time, so don't
bother stripping them.

[XTENSA] adjust boot linker script start addresses

2008-02-14T01:15:34+00:00

Move boot-redboot load address from 0xD0200000 to 0xD1000000
to make space for larger kernel images, in particular those with
an embedded initramfs filesystem.
Also properly set the ELF start address in boot-elf images so
that PC need not be set manually when loading them using GDB.

kbuild: restore arch/{ppc/xtensa}/boot cflags

2007-10-20T18:35:23+00:00

Commit 9a39e273d4df0560c724c5fe71f6314a0583ca2b removed the boot directory
addition to CFLAGS that was being used by the subdirectory builds.  For the
other files, that patch set EXTRA_CFLAGS, but Makefile.build explicitly
sets that to empty as it is explicitly for a single directory only.
Append to KBUILD_CFLAGS instead.

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.
