Chris Zankel a078ccff56 xtensa: fix redboot load address
With the patch to support MMUv3, the base address for the loaded

This fixes the RedBoot image.

Max Filippov 9ad79b5851 xtensa: drop CONFIG_EMBEDDED_RAMDISK
Remove Kconfig entries, boot subdirectory, dependencies from other
boot-* Makefiles, and sections from ld scripts.

Remove stale redboot code that used to pass initrd addresses in a3 and
a4 to _start.

Chris Zankel 367b8112fe xtensa: move headers files to arch/xtensa/include
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.

Bob Wilson bdd362ff4f [XTENSA] Fix makefile to work with binutils-2.18.
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.

Marc Gauthier ed3174d93c [XTENSA] adjust boot linker script start addresses
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.

Sam Ravnborg a0f97e06a4 kbuild: enable 'make CFLAGS=...' to add additional options to CC
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.

Chris Zankel 173d668138 [PATCH] xtensa: remove extra header files
The Xtensa port contained many header files that were never needed.  This
rather lengthy patch removes all those files.  Unfortunately, there were
many dependencies that needed to be updated, so this patch touches quite a
few source files.
