If this is an ELF file, you can put the exception vectors in a
separate segment.  Or if you don't need the entry point to
be in the low region, (and you don't need that unless your
boot loader ignores the entry point in the ELF header), you can
copy the vectors in at startup and have no code linked at 0 at
all.

No you cant. When flashed in ROM, the HV expands the bootloader binary
at 0 and jumps to 0x100
