262ae0a619 push LOAD_ADDR out to arch mk files
Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in
the standalone Makefile, push the setting up of LOAD_ADDR out to the arch
config.mk (and rename to STANDALONE_LOAD_ADDR in the process).  This keeps
the common code clean and lets the arch do whatever crazy crap it wants in
its own area.

f772acf8a5 ARM: compiler options cleanup - improve tool chain support
For some time there have been repeated reports about build problems
with some ARM (cross) tool chains.  Especially issues about
(in)compatibility with the tool chain provided runtime support
library libgcc.a caused to add and support a private implementation
of such runtime support code in U-Boot.  A closer look at the code
indicated that some of these issues are actually home-made.  This
patch attempts to clean up some of the most obvious problems and make
building of U-Boot with different tool chains easier:

- Even though all ARM systems basicy used the same compiler options
  to select a specific ABI from the tool chain, the code for this was
  distributed over all cpu/*/config.mk files.  We move this one level
  up into lib_arm/config.mk instead.

- So far, we only checked if "-mapcs-32" was supported by the tool
  chain; if yes, this was used, if not, "-mabi=apcs-gnu" was
  selected, no matter if the tool chain actually understood this
  option.  There was no support for EABI conformant tool chains.
  This patch implements the following logic:

  1) If the tool chain supports
	"-mabi=aapcs-linux -mno-thumb-interwork"
     we use these options (EABI conformant tool chain).
  2) Otherwise, we check first if
	"-mapcs-32"
     is supported, and then check for
	"-mabi=apcs-gnu"
     If one test succeeds, we use the first found option.
  3) In case 2), we also test if "-mno-thumb-interwork", and use
     this if the test succeeds. [For "-mabi=aapcs-linux" we set
     "-mno-thumb-interwork" mandatorily.]

  This way we use a similar logic for the compile options as the
  Linux kernel does.

- Some EABI conformant tool chains cause external references to
  utility functions like raise(); such functions are provided in the
  new file lib_arm/eabi_compat.c

  Note that lib_arm/config.mk gets parsed several times, so we must
  make sure to add eabi_compat.o only once to the linker list.

59b4d7471c ARM EABI: add new helper functions resp. function names
The ARM EABI defines new names for GCC helper functions,
and GCC seems to need some new functions as well.

This patch is a minimal-invasive approach to fix problems with EABI
conformant tool chains (to be used with "USE_PRIVATE_LIBGCC=yes").

52b1bf2c5c Make linking against libgcc configurable
Many (especially ARM) tool chains seem to come with broken or
otherwise unusable (for the purposes of builing U-Boot) run-time
support libraries `libgcc.a'. By using the "USE_PRIVATE_LIBGCC"
setting we allow to use alternative libraries instead.

"USE_PRIVATE_LIBGCC" can either be set as an environment variable in
the shell, or as a command line argument when running "make", i. e.
	$ make USE_PRIVATE_LIBGCC=yes
or
	$ USE_PRIVATE_LIBGCC=yes
	$ export USE_PRIVATE_LIBGCC
	$ make

The value of "USE_PRIVATE_LIBGCC" is the name of the directory which
contains the alternative run-time support library `libgcc.a'. The
special value "yes" selects the directory $(OBJTREE)/lib_$(ARCH) .

Note that not all architectures provide an alternative `libgcc.a' in
their lib_$(ARCH) directories - so far, only ARM does.

52cb4d4fb3 stdio/device: rework function naming convention
So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

c790b04d23 lib_arch/board.c: Move malloc initialization before flash_init()
This patch moves the malloc initialization before calling flash_init().
Upcoming changes to the NOR FLASH common CFI driver with optional
MTD infrastructure and MTD concatenation support will call malloc().
And nothing really speaks against enabling malloc just a little earlier
in the boot stage. Some architectures already enable malloc before
calling flash_init() so they don't need any changes here.

f96b44cef8 ARM: set GD_FLG_RELOC for boards skipping relocation to RAM
If CONFIG_SKIP_RELOCATE_UBOOT is set the flag GD_FLG_RELOC is usually
never set, because relocation to RAM is actually never done by U-boot
itself. However, several pieces of code check if this flag is set at
some time.

So, to make sure this flag is set on boards skipping relocation, this
is added to the initialisation of U-boot at a moment where it is safe
to do so.
