It avoids the need to read anything other than the rela descriptor, and thus makes relocation faster. > Why aarch64-gcc use rela format only instead of supporting two format? > these confuse me a few months. It's probably specified by the ABI which type to use, and it's not worth adding toolchain support for something different just for weird cases like this. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
