Fix alignment fault on ARM when running modules. With out an explicit
linker file gcc4.2.1 will half word align __bss_start's value. The word
dereference will crash hello_world.

This patch adds common infrastructure code for the Atmel AVR32
architecture. See doc/README.AVR32 for details.
Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
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.
-Fix asm/io.h macros
-Eliminate use of CACHE_BYPASS in cpu code

* Patch by Steven Scholz, 29 Sep 2003:
- A second parameter for bootm overwrites the load address for
"Standalone Application" images.
- bootm sets environment variable "filesize" to the resulting
(uncompressed) data length for "Standalone Application" images
when autostart is set to "no". Now you can do something like
if bootm $fpgadata $some_free_ram ; then
fpga load 0 $some_free_ram $filesize
