	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
	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.

	2e5f844 Browse files » rpi: Implement PSCI CPU_OFF ... We simulate the PSCI CPU_OFF operation by reseting the core via RMR. For secondaries, that already puts them in the holding pen waiting for a "warm boot" request as part of PSCI CPU_ON. For the BSP, we have to add logic to distinguish a regular boot from a CPU_OFF state, where, like the secondaries, the BSP needs to wait foor a "warm boot" request as part of CPU_ON. Testing done: - ACS suite now passes more tests (since it repeatedly calls code on secondaries via CPU_ON). - Linux testing including offlining/onlineing CPU0, e.g. "echo 0 > /sys/devices/system/cpu/cpu0/online".

	af2a487 Browse files » rpi: rpi3_pwr_domain_on(): Use MMIO accessor ... When writing to arbitrary locations in memory using a constructed pointer, there is no guarantee that the compiler does not optimise away the access, since it cannot detect any dependency. One typical solution is to use the "volatile" keyword, but using MMIO accessors in usually the better answer, to avoid torn writes. Replace the usage of an array with such an MMIO accessor function in rpi3_pwr_domain_on(), to make sure the write is really happening.

Unify the two files, moving it into the common/ directory. This adds a plat_rpi_get_model() function, which can be used to trigger RPi4 specific action, detected at runtime. We use that to do the RPi4 specific L2 cache initialisation.
