* elflink: Make ELF the default object formatMatt Fleming2011-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | com32/elflink/modules was originally created to house ELF modules and keep them separate from the COM32 modules as the elflink branch was being developed. However, this has inadvertently created a maintenance nightmare because code was copied from elsewhere in the tree into com32/elflink/modules, resulting in duplication. Bug fixes have been going into the original code but have not been merged onto the elflink branch, leaving the duplicate code in com32/elflink/modules buggy. So let's delete this directory. There really is no reason to keep ELF and COM32 modules separate because there's no reason to need both COM32 and ELF modules to coexist. ELF is a far superior object file format and all modules are not emitted as ELF objects. Now that we're outputting ELF modules we can use dynamic memory instead of the cs_bounce bounce buffer. This commit requires a certain amount of shuffling for some files. quicksort.c isn't a module and belongs as part of the util library. cli.h belongs in com32/include so that other modules can make use of the cli code in ldlinux.c32. All libraries are now ELF shared libraries which are only loaded to fixup unresolved symbols for executable modules and renamed from *.a to *.c32. This reduces the runtime memory footprint because libraries are only loaded when needed and because every executable no longer gets its own copy of code/data (as it would if linking with a static library). Also, remove MINLIBOBJS from libcom32.c32 because it is already part of libcom32min.a and we don't want to have any duplicate symbols between the core (which links with libcom32min.a) and libcom32.c32.

* Makefile: Move Makefile fragments into mk/Matt Fleming2011-04-071-0/+27
Move the MCONFIG files into a mk/ directory and give them more descriptive names. This is purely a cosmetic change to make the 'include' directives a bit more coherent by making it obvious exactly which MCONFIG file we're including. For example, in com32/lua/src/Makefile we exchange the line, include ../../MCONFIG for the much more comprehensible, include $(MAKEDIR)/com32.mk Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>
