Patch from Nicolas Pitre

This patch allows for the kernel to be configured for XIP.
A lot of people are using semi hacked up XIP patches already so
it is a good idea to have a generic and clean implementation 
supporting all ARM targets. The patch isn't too intrusive.

It involves:

- modifying the kernel entry code to map separate .text and .data
  sections in the initial page table, as well as relocating
  .data to ram when needed

- modifying the linker script to account for the different VMA and
  LMA for .data, as well as making sure that .init.data gets
  relocated to ram

- adding the final kernel mapping with a new MT_ROM mem type

- distinguishing between XIP and non-XIP for bootmem and memory
  resource declaration

- and adding proper target handling to Makefiles.

While at it, this also cleans up the kernel boot code a bit
so the kernel can now be compiled for any address in ram,
removing the need for a relation between kernel address and
start of ram.  Also throws in some more comments.

And finally the _text, _etext, _end and similar variables are now
declared extern void instead of extern char, or even extern int.
That allows for operations on their address directly without any
cast, and trying to reference them by mistake would yield an 
error which is a good thing.

Tested both configurations: XIP and non XIP, the later 
producing a kernel for execution from ram just as before.

Patch from Sascha Hauer

This patch supports the Hynix developer boards h7201 and h7202 for the
HMS30C7201 and HMS30C7202 CPUs.

Changes to previous patch:
- reorganized file structure. We now have common.c which shares stuff
  common to all h720x processors and cpu-h720[12].c files for the cpu
  specific stuff
- fixed timer handling for timers 1/2
- cleaned up h720x register definitions and splitted in files specific
  to each cpu and one generic part

arm cpufreq Kconfig enhancements:
- don't force the deprecated 24_API on SA11x0 any more, as it will be removed
  ~2005-01-01 and different interfaces have been available for a long time
- don't mark CPU_FREQ as being EXPERIMENTAL any longer
- re-order it in the same way other arches are ordered

Patch from Lennert Buytenhek

Hi,

gcc doesn't understand 80-bit floating point on the ARM currently,
according to the kernel's Kconfig docs, but it would seem that the
current extended double emulation code is broken for big endian
platforms.

So, this patch disables NWFPE_XP on big endian architectures, until
someone comes round and fixes it.


cheers,
Lennert

Localize Kconfig debug options into one file (lib/Kconfig.debug)
for easier maintenance, searching, and menu-building.

Updated to 2.6.8.

Summary of changes:

. localizes the following symbols in lib/Kconfig.debug:
    DEBUG_KERNEL, MAGIC_SYSRQ, DEBUG_SLAB, DEBUG_SPINLOCK,
    DEBUG_SPINLOCK_SLEEP, DEBUG_HIGHMEM, DEBUG_BUGVERBOSE,
    DEBUG_INFO
  and FRAME_POINTER for some instances of it (if it's freely
  user-selectable) but not for the cases where it's forced or
  it depends on some other options.
. adds DEBUG_KERNEL requirement to some DEBUG_vars;
. remove KALLSYMS from S390-specific kernel hacking menu;
  use KALLSYMS in the EMBEDDED menu instead;
. add CRIS and M68KNOMMU symbols for use in lib/Kconfig.debug;
. eliminate duplicate "General setup" labels in sparc64 config;
. whitespace cleanup;
. fixed a few trival typos;

Patch from Sascha Hauer

This patch adds support for the Motorola i.MX SoC. It has board
support included for the MX1ADS Eval Board, but the patch has been
tested on two other custom boards as well.

Things changed since Patch 1955/2:
- fixed according to Russell's comments.
- removed unnecassary files from include/asm-arm/arch-imx.
- removed cpufreq support (it needs rework).
- made myself the Maintainer of mx1ads

Patch from Marc Singer

The work already done to rectify the timer code initialization missed
a necessary change.  This patch adds a timer initialization function
to the LPD7A400 machine type.  It also makes a small correction to the
kernel configuration that is out of step with the machine specific
Kconfig.

Patch from John Lenz

Cleanup and forward port of patch 1849.
This patch provides support for the SHARP LoCoMo device, 
a companion chip similar to the sa1111 device.  It is present
in many of the SHARP Zaurus line of PDAs.

This platform is no longer maintained, and its maintainer says that
the hardware is obsolete and out of circulation.

This cset adds the code to handle the hardware vector floating point
unit found on some ARM926 and later CPUs.  The hardware provides
an implementation for the common cases, and bounces exceptions for
other cases, which have to be handled in software, and signalling
SIGFPE as appropriate.

The code is completely out of date, I am no longer maintaining it, 
and nobdy has volunteered to do so; therefore, I am killing it.

Patch from Marc Singer

[if's replaced by ifdef's.]

While the BLOB boot loader doesn't support it, there are two others,
UBOOT and Logic's LOLO, that will initialize the SDRAM controller such
that the memory appears as a contiguous region.  This layout to be
required for WinCE and, thus, is the default for these loaders.  The
memory organization had been optimized for discontiguous blocks.  Now,
it supports a default mode that is compatible with all of the
bootloaders as well as options to optimize for either contiguous or
discontiguous models.

Withing, there is also a slight change to the way that the DEBUG_LL
macros select the UART address.  Now it uses immediate constants
exclusively.

- clear hwif->hw in setup-pci.c before using it

- fix arch/arm/Kconfig to allow IDE only on platforms supporting it

- introduce IDE_ARCH_OBSOLETE_INIT and ide_default_io_ctl() so
  we can use generic ide_init_hwif_ports() and kill no longer needed
  <asm-arm/arch-*/ide.h> (leave broken lh7a40x and sa1100 versions)

Cross-compile tested on ARM.

Fix selection configuration entry for UART number for low-level debug

IXP4xx family of network processors. The code still needs some
cleanup here and there, but it's to the point that it's should
be OK to push upstream.

Some of the remaining TODOs:

- Cleanup GPIO IRQ handling for edge-trigered HW (none exists ATM)
- Add IDE driver for various platforms
- Misc cleanups

This patch adds the changes to arch/arm/Makefile and arch/arm/Kconfig

Patch from Marc Singer

Updated change set for the 2.6.5 kernel *and* for the April 8th arm
patch.  Also included are changes suggested by Russell that merge
several of the files in the mach- directory.  I have also endeavored
to remove all unnecessary whitespace additions.

Note that since I've found the cause of an annoying user-space crash,
I believe that this patch is OK.  The crash appears to have nothing to
do with the system setup.

Since this is currently ARM-only, I've dropped the drivers/Kconfig
change for the time being.

Latest (and hopefully last :) patch for generic DMA buffer bouncing.

- Fixed SA1111 dma_needs_bounce
- Added check for out of bounds buffers.
- Made dmabounce.c directly implement dma_* API

Note that I didn't do the following:

#ifndef CONFIG_DMABOUNCE
inline implementations of all functions
#else
extern declarations
#endif

Instead I wrapped it individual in #ifndef/#else blocks to keep the
comments in the same area as function declarations.  IMHO this makes 
it easier for someone to go look at the comments if they need to know 
what a specific API does.

This cset adds minimal support for ARM Ltd's ARM926EJ-S "Versatile"
platform.

The machine class should be in alphabetical order.  Swap ordering

Patch from Tony Lindgren

This patch updates the ARM Linux core files to add support for 
Texas Instruments OMAP-1510, 1610, and 730 processors. 

OMAP is an embedded ARM processor with integrated DSP.

OMAP-1610 has hardware support for USB OTG, which might be of interest
to Linux developers. OMAP-1610 could be easily be used as development 
platform to add USB OTG support to Linux.

This patch is an updated version of an earlier patch 1767/1 
with the dummy Kconfig added for OMAP as suggested by Russell King
here:

http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=1767/1

This patch is brought to you by various linux-omap developers.

Anakin has not been maintained since it was (partially) merged, and
the maintainers appear to ignore mail about it.  No one appears
willing to maintain it either.  However, some unrelated kernel
maintainers have been updating various files while they've been
working in the area - which is wasted work for something which
isn't maintained.

Therefore, this cset removes Anakin completely from the kernel.
