dd04734491 Top-level SConsctruct can now retrive shelved configuration 
By moving shelve retrieval details to configuration_retrieve()
into configuration.py, the top-level SConstruct can now get full
configuration object from shelve.

59f30a175a More progress on build scripts 
Created a config directory for configuration files.
Moved all absolute path variables to a projpaths.py file
All scripts can now universally learn absolute paths via projpaths.py
Moved the config_symbols class to the configuration.py file.
Moved libs to loader since they are only referred by the loader

8ffd4537ea Added newer platform files. 
The build can now be done with fine-grain conditions on how to determine
drivers, platforms, arch, subarch etc.

b0f248a866 Put back the full list of default build products so that "scons -U" from subdirectories works as expected. 2009-09-01 11:33:48 +01:00

5974a327d0 Various changes post sorting out some of the issues regarding task ordering. 
test0 cannot be the first task in the list as it must have a prior physical_base.lds in order to create test_exec_linker.lds.
mm0 appears to have to precede fs0 for the tests to execute on start.  This should be considered a bug.

5987773f3c First attempt at splitting out the containers build from the SConstruct. 
This creates a runnable final.axf, but the load is not correct and the tests fail to execute.

c311cf72e6 Rearrange the environment construction to support changing toolchain. 2009-08-28 11:49:05 +01:00
Russel Winder
03205855cc Generalize the configuration processing so that the top-level SConstruct only processes the ARCH symbol and prepares the PLATFORM and SUBARCH entries so as to write the config.h. Everything is now entered in the environment so the SConscript files can be responsible fo rthe processing. 2009-08-28 10:39:19 +01:00

a41caeebd2 Created libc under containers/posix which now all tasks use to build. 
There is a problem in the new libc that test0 now misbehaves. Going to be fixed.

ce62459d13 Correct the problem of not loading test_exec. 
Remove the linker script and assembler load source in favour of generating
the source so that the correct path is in the source.
