fix(xlat): check definition of PLAT_XLAT_TABLES_DYNAMIC flag

2026-09-07T11:41:30+00:00

When enabling -Wundef, we can see this warning: include/lib/xlat_tables/xlat_tables_v2_helpers.h:81:5: error: 'PLAT_XLAT_TABLES_DYNAMIC' is not defined, evaluates to '0' [-Werror=undef] 81 | #if PLAT_XLAT_TABLES_DYNAMIC | ^~~~~~~~~~~~~~~~~~~~~~~~ As the flag can be defined either with `call add_defines`, or directly added to BL*_CFLAGS, the easier way to correct those warning is to first check the flag is defined and then that it is set, with: `#if defined(PLAT_XLAT_TABLES_DYNAMIC) && PLAT_XLAT_TABLES_DYNAMIC` Change-Id: Ifbd20161d90e3eab46352393760fb0c01d24785c Signed-off-by: Yann Gautier

fix(el3-runtime): add some missing prototypes

2026-09-07T11:41:30+00:00

When compiling with -Werror=missing-prototypes, 2 functions are missing their prototypes in header file: handler_interrupt_exception() and handler_sync_exception(). Add them in runtime_svc.h. The stdint.h include is also added to context_el1.h, or else there are compilation errors for uint64_t being undefined. And it is moved before ENABLE_FEAT_D128 flag in sysreg128.h, as uint64_t is also used in the #else part. Change-Id: I88177af229430b19715557c39da64ae0780d43d4 Signed-off-by: Yann Gautier

fix(libc): define __BSD_VISIBLE to 0

2026-09-07T11:37:22+00:00

This is defined (under conditions) in sys/cdefs.h, but the file is never used, we have a cdefs.h in include/lib/libc instead. As the flag is not used, and can cause compilation warning when including endian.h, define it to 0 in the cdefs.h file we use.

feat(cpus): add support for the Cortex-X1C CPU

2026-08-20T06:56:05+00:00

This is a C variant of the Cortex-X1 core. Copy its enablement and port any errata that also apply - most of the errata on the original are not present on the C variant. Change-Id: Idd8eba7e99abd0839eafde53bd69d9b20a88ed1a Signed-off-by: Boyan Karatotev

feat(cpus): add support for the Cortex-A520AE CPU

2026-08-20T06:56:05+00:00

This is an AE variant of the Cortex-A520 core. Copy its enablement and port any errata that also apply - most of the errata on the original are not present on the AE variant. Change-Id: Ic34b7e3b5e4a9defe79c11be0b3251f6275b5303 Signed-off-by: Boyan Karatotev

feat(cpus): add support the Venom AE CPU

2026-08-20T06:56:05+00:00

This is an AE variant of the Venom CPU. Change-Id: Id50f44a42acdddb6e2b8188bab9970019b71838c Signed-off-by: Boyan Karatotev

refactor(cpus): align AE variant core names

2026-08-20T06:52:51+00:00

We've ended up with two ways of naming AE variants of cores: ae and _ae. Standardise around the first one for consistency with the C variants of cores. Change-Id: I999ed43421d083af148c3e92cef9d8ca5c635277 Signed-off-by: Boyan Karatotev

* changes: fix(cpus): add workaround for C1-Nano erratum 4497400 fix(cpus): add workaround for Cortex-A520 erratum 4491980 fix(cpus): add workaround for Cortex-A510 erratum 4568615

fix(cpus): workaround for C1-Pro erratum 3773617

2026-08-04T13:11:53+00:00

C1-Pro erratum 3773617 affects revision r1p1 and is fixed in revision r1p2. It causes ICH_VMCR_EL2.VBPR1 to return incorrect data when it is written with one SCR_EL3.NS value and subsequently read with the other. The required SCR_EL3.NS handling when saving and restoring ICH_VMCR_EL2 is already implemented. Register C1-Pro erratum 3773617 with the existing common workaround so that it is applied on r1p1. Refer https://support.arm.com/documentation/SDEN-3273080/latest Change-Id: I9b83add5d104f4621520c8e90777f10c7a97dad5 Signed-off-by: Matthew Ellis

fix(cpus): add workaround for Cortex-A510 erratum 4568615

2026-08-03T14:21:55+00:00

The weakness is that EL3's secret data may be exposed to a lower EL via a side channel. The workaround is to overwrite any data in this side channel with publicly visible data using a core specific sequence.
