	06aca85 Browse files » xlat lib v2: Add support to pass shareability attribute for normal memory region ... Present framework restricts platform to pass desired shareability attribute for normal memory region mapped in MMU. it defaults to inner shareability. There are platforms where memories (like SRAM) are not placed at snoopable region in advaned interconnect like CCN/CMN hence snoopable transaction is not possible to these memory. Though These memories could be mapped in MMU as MT_NON_CACHEABLE, data caches benefits won't be available. If these memories are mapped as cacheable with non-shareable attribute, when only one core is running like at boot time, MMU data cached could be used for faster execution. Hence adding support to pass the shareability attribute for memory regions.

	9cefb4b Browse files » Pass more -D options to BL_CPPFLAGS instead of BL_CFLAGS ... Commit d5e97a1d2c79 ("Build: define IMAGE_AT_EL1 or IMAGE_AT_EL3 globally for C files") does not have commit 848a7e8ce1d9 ("Build: introduce per-BL CPPFLAGS and ASFLAGS") as an ancestor because they were pulled almost at the same time. This is a follow-up conversion to be consistent with commit 11a3c5ee7325 ("plat: pass -D option to BL_CPPFLAGS instead of BL_CFLAGS"). With this change, the command line option, IMAGE_AT_EL3, will be passed to .S files as well. I remove the definition in include/lib/cpus/aarch64/cpu_macros.S Otherwise, the following error would happen. include/lib/cpus/aarch64/cpu_macros.S:29:0: error: "IMAGE_AT_EL3" redefined [-Werror] Change-Id: I943c8f22356483c2ae3c57b515c69243a8fa6889 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Masahiro Yamada committed on 2 Apr 2020
	268131c Browse files » xlat_tables_v2: fix assembler warning of PLAT_RO_XLAT_TABLES ... If PLAT_RO_XLAT_TABLES is defined, the base xlat table goes to the .rodata section instead of .bss section. This causes a warning like: /tmp/ccswitLr.s: Assembler messages: /tmp/ccswitLr.s:297: Warning: setting incorrect section attributes for .rodata It is practically no problem, but I want to keep the build log clean. Put the base table into the "base_xlat_table" section to suppress the assembler warnings. The linker script determines its final destination; rodata section if PLAT_RO_XLAT_TABLES=1, or bss section otherwise. So, the result is the same.

	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).

	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.
