2020-04-25	caa3e7e Browse files » linker_script: move .data section to bl_common.ld.h ... Move the data section to the common header. I slightly tweaked some scripts as follows: [1] bl1.ld.S has ALIGN(16). I added DATA_ALIGN macro, which is 1 by default, but overridden by bl1.ld.S. Currently, ALIGN(16) of the .data section is redundant because commit 412865907699 ("Fix boot failures on some builds linked with ld.lld.") padded out the previous section to work around the issue of LLD version <= 10.0. This will be fixed in the future release of LLVM, so I am keeping the proper way to align LMA. [2] bl1.ld.S and bl2_el3.ld.S define __DATA_RAM_{START,END}__ instead of __DATA_{START,END}__. I put them out of the .data section. [3] SORT_BY_ALIGNMENT() is missing tsp.ld.S, sp_min.ld.S, and mediatek/mt6795/bl31.ld.S. This commit adds SORT_BY_ALIGNMENT() for all images, so the symbol order in those three will change, but I do not think it is a big deal.

2020-04-02	a7739bc Browse files » linker_script: move bss section to bl_common.ld.h ... Move the bss section to the common header. This adds BAKERY_LOCK_NORMAL and PMF_TIMESTAMP, which previously existed only in BL31. This is not a big deal because unused data should not be compiled in the first place. I believe this should be controlled by BL*_SOURCES in Makefiles, not by linker scripts. I investigated BL1, BL2, BL2U, BL31 for plat=fvp, and BL2-AT-EL3, BL31, BL31 for plat=uniphier. I did not see any more unexpected code addition. The bss section has bigger alignment. I added BSS_ALIGN for this. Currently, SORT_BY_ALIGNMENT() is missing in sp_min.ld.S, and with this change, the BSS symbols in SP_MIN will be sorted by the alignment. This is not a big deal (or, even better in terms of the image size).

2020-04-02	0a0a7a9 Browse files » linker_script: replace common read-only data with RODATA_COMMON ... The common section data are repeated in many linker scripts (often twice in each script to support SEPARATE_CODE_AND_RODATA). When you add a new read-only data section, you end up with touching lots of places. After this commit, you will only need to touch bl_common.ld.h when you add a new section to RODATA_COMMON. Replace a series of RO section with RODATA_COMMON, which contains 6 sections, some of which did not exist before. This is not a big deal because unneeded data should not be compiled in the first place. I believe this should be controlled by BL*_SOURCES in Makefiles, not by linker scripts. When I was working on this commit, the BL1 image size increased due to the fconf_populator. Commit c452ba159c14 ("fconf: exclude fconf_dyn_cfg_getter.c from BL1_SOURCES") fixed this issue. I investigated BL1, BL2, BL2U, BL31 for plat=fvp, and BL2-AT-EL3, BL31, BL31 for plat=uniphier. I did not see any more unexpected code addition.

2020-04-01	9fb288a Browse files » linker_script: move more common code to bl_common.ld.h ... These are mostly used to collect data from special structure, and repeated in many linker scripts. To differentiate the alignment size between aarch32/aarch64, I added a new macro STRUCT_ALIGN. While I moved the PMF_SVC_DESCS, I dropped #if ENABLE_PMF conditional. As you can see in include/lib/pmf/pmf_helpers.h, PMF_REGISTER_SERVICE* are no-op when ENABLE_PMF=0. So, pmf_svc_descs and pmf_timestamp_array data are not populated.

This patch moves all GICv3 driver files into new added 'gicv3.mk' makefile for the benefit of the generic driver which can evolve in the future without affecting platforms. The patch adds GICv3 driver configuration flags 'GICV3_IMPL', 'GICV3_IMPL_GIC600_MULTICHIP' and 'GICV3_OVERRIDE_DISTIF_PWR_OPS' described in 'GICv3 driver options' section of 'build-option.rst' document. NOTE: Platforms with GICv3 driver need to be modified to include 'drivers/arm/gic/v3/gicv3.mk' in their makefiles.

2020-03-10	665e71b Browse files » Factor xlat_table sections in linker scripts out into a header file ... TF-A has so many linker scripts, at least one linker script for each BL image, and some platforms have their own ones. They duplicate quite similar code (and comments). When we add some changes to linker scripts, we end up with touching so many files. This is not nice in the maintainability perspective. When you look at Linux kernel, the common code is macrofied in include/asm-generic/vmlinux.lds.h, which is included from each arch linker script, arch/*/kernel/vmlinux.lds.S TF-A can follow this approach. Let's factor out the common code into include/common/bl_common.ld.h As a start point, this commit factors out the xlat_table section.
