When CONFIG_LLEXT_TYPE_ELF_RELOCATABLE is active, bypass appending static address flags (-Ttext, --section-start, -Tdata) in the linker helper script. This keeps section base addresses at 0. Also adjust the offset calculator to avoid integer parsing errors when all section addresses are set to 0. Signed-off-by: Liam Girdwood <[email protected]>
…table modules Implement page-level virtual memory mapping using Zephyr's sys_bitarray utility over the library region. Compile section layout at load-time to allocate virtual addresses and rewrite section sh_addr headers in-place. This enables Zephyr LLEXT to naturally relocate references.

Enable CONFIG_LLEXT_EXPORT_BUILTINS_BY_SLID=y in llext_relocatable.conf to link relocatable LLEXT modules against build-time function signature hashing, providing load-time ABI mismatch protection. Signed-off-by: Liam Girdwood <[email protected]>

Fully relocatable modules, they - TODO need to reuse virtual memory block allocator.
