Hi, The patch series adds:
- Archive or library searching for unresolved symbols loading the first object file that provdes the symbol. - Large memory support for architectures that use small relative branch instructions. - Libdl small data support for the PowerPC. - Increase the psim BSP's memory size to 256M. Archive search and loading of objects is controlled by a configuration file that lists the libraries on the target. The search continues until all unresolved symbols are checkied in all archives and they remain unresolved. The feature lets you load system libraries onto a target and have the code loaded and integrated into the running application. Large memory support is added for ARM and PowerPC architectures. This allows these architectures to place object files anywhere in the address space. Libdl adds trampolines to extend a range limited branch instruction to the entire address space. Currently the trampoline table is at the lower end of an object's files resident address base. PowerPC small data is now supported. Small data is a system wide maximum 64K region of memory controlled by the compiler. Access to data in this region is typically faster because a small relative offset is used. Libdl now has an allocator for this memory and it can allocate space to loaded object files. The space available is determined by the linker command file for the BSP. Currently the psim BSP allocates the maximum space. Other PowerPC BSPs will need to have space allocated for some of the DL test ito pass. There are other small fixes including a memory leak.
