Using -fno-toplevel-reorder causes gcc to not reorder functions.  This
ensures that an application's entry point will be the first function in
the application's source file.

This change, along with commit 620bbba5
should cause a standalone application's entry point to be at the base of
the compiled binary.  Previously, the entry point could change depending
on gcc version and flags.

Note -fno-toplevel-reorder is only available in gcc version 4.2 or
greater.

Previously, standalone applications were compiled with gcc flags that
produced relocatable executables on the PowerPC architecture (eg with
the -mrelocatable and -fPIC flags).  There's no reason for these
applications to be fully relocatable at this time since no relocation
fixups are performed on standalone applications.

Additionally, removing the gcc relocation flags results in the entry
point of applications residing at the base of the image.  When
a standalone application was relocatable, the entry point was generally
located at an offset into the image which was confusing and prone to
errors.

This change moves the entry point of PowerPC standalone applications
from 0x40004 (usually) to 0x40000.

Some versions of 'make' do not handle trailing white-spaces
properly. Trailing spaces in ELF causes a 'fake' source to
be added to the variable COBJS; leading to build failure
(listed below). The problem was found with GNU Make 3.80.

Using text-function 'strip' as a workaround for the problem.

Clean up the arch/cpu/board/config checks as well as redundant setting of

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.

Atmel DataFlashes by default operate with pages that are slightly bigger
than normal binary sizes (i.e. many are 1056 byte pages rather than 1024
bytes).  However, they also have a "power of 2" mode where the pages show
up with the normal binary size.  The latter mode is required in order to
boot with a Blackfin processor, so many people wish to convert their
DataFlashes on their development systems to this mode.  This standalone
application does just that.

The attached patch corrects an error in the examples/Makefile which
causes the applications in the examples directory to hang on OMAP3
based boards. The current Makefile sets -Ttext during linking to
0x0c100000 which is outside of addressable SDRAM memory. The script
corrects the existing ifeq...else...endif logic to look at the VENDOR
tag rather than the CPU tag.

The patch affects the following configs: omap3_beagle_config,
omap3_overo_config, omap3_evm_config, omap3_pandora_config,
omap3_zoom1_config and omap3_zoom2_config.

A forward port of the last version to work with the newer smc911x driver.
I only have a board with a LAN9218 part on it, so that is the only one
I've tested.  But there isn't anything in this that would make it terribly

Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
