hi Albert, I am facing an issue with generation of AIS signed binaries for hawkboard. The aisgen utility takes the u-boot elf file as input and generates a ais binary, which is the file format recognised by the hawkboard's RBL(rom bootloader). After the relocation support for ARM, the elf file generated has file type as 'DYN (shared object)'. With this, the aisgen tool rejects the file as not being an elf file.
Can you please tell me what could have caused this change. I compiled u-boot for a powerpc board, and found that the file type in that case is 'ELF Executable'. Is there any specific reason why the file type has changed for ARM, as powerpc also supports relocation.
