This section contain the table needed for dynamic relocation. Also provide symbols for the relocation code to access the table. Discard all sections which are not needed in the final ELF binary and U-Boot image. Section .dynsym cannot be discarded or GNU ld crashes otherwise. This section will be stripped by GNU objcpy in a later patch. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
