It would make the linker script a bit uglier.

When it is built with ENABLE_PIE=1, some sections are inserted before the executable code. $ make PLAT=uniphier CROSS_COMPILE=aarch64-linux-gnu- ENABLE_PIE=1 bl31 $ aarch64-linux-gnu-objdump -h build/uniphier/release/bl31/bl31.elf \| head -n 13 build/uniphier/release/bl31/bl31.elf: file format elf64-littleaarch64 Sections: Idx Name Size VMA LMA File off Algn 0 .dynsym 000002a0 0000000081000000 0000000081000000 00010000 23 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .dynstr 000002a0 00000000810002a0 00000000810002a0 000102a0 20 CONTENTS, ALLOC, LOAD, READONLY, DATA 2 .hash 00000124 0000000081000540 0000000081000540 00010540 23 CONTENTS, ALLOC, LOAD, READONLY, DATA 3 ro 0000699c 0000000081000664 0000000081000664 00010664 211 CONTENTS, ALLOC, LOAD, CODE The previous stage loader generally jumps over to the base address of BL31, where no valid instruction exists. I checked the linker script of Linux (arch/arm64/kernel/vmlinux.lds.S) and U-Boot (arch/arm/cpu/armv8/u-boot.lds), both of which support relocation. They simply discard those sections. Do similar in TF-A too. Change-Id: I6c33e9143856765d4ffa24f3924b0ab51a17cde9 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Masahiro Yamada committed on 24 Jan 2020
	320920c Browse files » PIE: pass PIE options only to BL31 ... docs/getting_started/build-options.rst clearly says ENABLE_PIE is currently only supported in BL31, but in fact, it has a stronger limitation: Defining ENABLE_PIE may corrupt BL1 and BL2. So, ENABLE_PIE is supported only for platforms where BL31 is the only image built in the TF-A tree. Currently, ENABLE_PIE is enabled by two platforms, plat/arm/common/arm_common.mk and ti/k3/common/plat_common.mk, both of which enable ENABLE_PIE together with RESET_TO_BL31. For platforms with the full boot sequence, ENABLE_PIE may break earlier BL stages. For example, if I build PLAT=qemu with ENABLE_PIE=1, it fails in BL1. When ENABLE_PIE is enabled, PIE options are added to TF_CFLAGS and TF_LDFLAGS, so all BL images are affected. It is problematic because currently only the BL31 linker script handles it. Even if BL1/BL2 works, the image size would increase needlessly, at least. Pass the PIE options only to BL images that support it.

	d986bae Browse files » Build: support per-BL LDFLAGS ... make_helpers/build_macros.mk supports per-BL CFLAGS. For example, you can pass compiler flags only to BL31 by using BL31_CFLAGS. This commit adds per-BL LDFLAGS support, which is useful as well. My main motivation of this addition is to use it for ENABLE_PIE. When ENABLE_PIE is enabled, some linker flags are added to TF_LDFLAGS, which affects all the TF images. It will make more sense to pass the relevant options only to BL images that support it.
