I reproduced your initial email sent Dec 18th 2025 below and Cced relevant folks just in case. Regards, Olivier. ____________________________________________________________ Hello, I'm firmware developer for RD-V3-R1 chipset. I have developed our firmware based on Neoverse Reference Platform RD-INFRA-2025.07.03, but I have also kept an eye on the code to ensure we remain in step with the latest release. While inquiring on the TF-M forum to update the TF-M code, I also developed a query regarding the TF-A section. Re: Several Questions related to RSE Provisioning - TF-M - lists.trustedfirmware.org<https://lists.trustedfirmware.org/archives/list/tf-m@lists.trustedfirmware.…> This link includes that RSE API codes are removed in the SotA TF-A codes. I check this in the TF-A commit. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/46314 I was already aware that this API was not used outside of test code. However, I would like to know the reason why that code was removed, beyond the simple fact that it was not being used. Is it possible that Chain-of-Trust is established in whole firmware stack from RSE ROM to AP BL33 bootloader, without RSE assist? If possible, what does TF-A rely upon as the basis for trust in establishing the Root of Trust? Our team believed that CoT was established on the premise of the RSE API, and was therefore designing to ensure the trustworthiness of the entire firmware using that code. However, we recognise that to use the latest version of the code, we must abandon that belief and design in a different manner. Before the new version of RD-INFRA is released, we intend to resolve this internally as a team. Should you feel the scope of the question extends beyond what is typically addressed in the forum, please do not hesitate to let us know. Thank you for reading this mail. Best Regard, Taehoon Kim

[RFE] lib/el3_runtime: set NS bit if secure el2 is not implemented

by Pawandeep Oza (QUIC)

Please have a look at following patch, where on our platform we try to maintain single image of TFA (for custom CPU and Cortex A55) Cortex A55 does not have Secure EL2 implemented, while on the other hand our custom CPU has secure EL2 (and we run Hafnium there) On Cortex A55 ARM AEM model: write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); the context was set before as u_register_t icc_sre_el2_val = ICC_SRE_DIB_BIT | ICC_SRE_DFB_BIT | ICC_SRE_EN_BIT | ICC_SRE_SRE_BIT; and setting ICC_SRE_DIB_BIT | ICC_SRE_DFB_BIT causes crash since secure EL2 is not implemented. resulting into following patch which resolves the issue. seeking feedback/discussion if I can post it to upstream TFA, let me know if I am missing something here. lib/el3_runtime: set NS bit if secure el2 is not implemented before setting icc_sre_el2 set NS bit for non-secure context so that the ICC_SRE_DIB_BIT and ICC_SRE_DFB_BIT are preserved Signed-off-by: Oza Pawandeep <quic_poza(a)quicinc.com> diff --git a/lib/el3_runtime/aarch64/context_mgmt.c b/lib/el3_runtime/aarch64/context_mgmt.c index e31255868..5100f2f00 100644 --- a/lib/el3_runtime/aarch64/context_mgmt.c +++ b/lib/el3_runtime/aarch64/context_mgmt.c @@ -1411,7 +1411,18 @@ static void el2_sysregs_context_restore_gic(el2_sysregs_t *ctx, uint32_t securit u_register_t scr_el3 = read_scr_el3(); #if defined(SPD_spmd) && SPMD_SPM_AT_SEL2 - write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); + if (is_feat_sel2_supported()) { + write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); + } else { + write_scr_el3(scr_el3 | SCR_NS_BIT); + isb(); + + write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); + + write_scr_el3(scr_el3); + isb(); + } + #else write_scr_el3(scr_el3 | SCR_NS_BIT); isb(); Regards, Oza.

TF-A Tech Forum Dec 11th 4.00pm (UK) - TF-RMM Live Firmware Activation (design update)

by Olivier Deprez

Hi, On Dec 11th in the TF-A Tech Forum at 4.00pm UK, Soby Mathew will present a design update on TF-RMM Live Firmware Activation: This presentation describes the revised TF-RMM Low-VA MMU and global-runtime-data design required to support Live Firmware Activation (LFA). Compared to the earlier approach (outlined in the TFA Tech Forum session on 12-Jun-2025 [1] ), which assumed mostly fixed boot time mappings and per-platform handcrafted Low-VA contexts, the new design is driven by several changes in RMM specification: RMM must now support runtime mapping/unmapping of PAs for RMM objects like struct granule , reuse those dynamic mappings across LFA transitions. These PAs can come either from NS world at runtime or EL3 reservation from RMM carveout. In order to migrate Stage 1 dynamic mappings across LFA instances, RMM needs to reduce dependence on platform-specific MMU setup, and provide a structured framework for allocating, versioning and migrating global runtime data.

TF-A Tech Forum Dec 11th 4.00pm (UK) - TF-RMM Live Firmware Activation (design update)

by Olivier Deprez

Hi, On Dec 11th in the TF-A Tech Forum at 4.00pm UK, Soby Mathew will present a design update on TF-RMM Live Firmware Activation: This presentation describes the revised TF-RMM Low-VA MMU and global-runtime-data design required to support Live Firmware Activation (LFA). Compared to the earlier approach (outlined in the TFA Tech Forum session on 12-Jun-2025 [1] ), which assumed mostly fixed boot time mappings and per-platform handcrafted Low-VA contexts, the new design is driven by several changes in RMM specification: RMM must now support runtime mapping/unmapping of PAs for RMM objects like struct granule , reuse those dynamic mappings across LFA transitions. These PAs can come either from NS world at runtime or EL3 reservation from RMM carveout. In order to migrate Stage 1 dynamic mappings across LFA instances, RMM needs to reduce dependence on platform-specific MMU setup, and provide a structured framework for allocating, versioning and migrating global runtime data. The Stage 1 Low-VA is therefore split into static and dynamic regions managed by the common xlat layer. The detailed design is captured in the TF-RMM wiki RFC “TF-RMM Live Firmware Activation [2]” and builds on the initial design presented in the TFA Tech Forum session on 12-Jun-2025 [1] : [1] Previous LFA discussion: https://github.com/TF-RMM/tf-rmm/wiki/TFA-Tech-Forum-Presentations [2] https://github.com/TF-RMM/tf-rmm/wiki/RFC:-TF%E2%80%90RMM-Live-Firmware-Act… Regards, Olivier.

Non volatile boot index for the purpose of firmware update

by Patryk

Hi I'm looking for a suggestion for a reliable place to store a small boot index for PSA Firmware Update. SNVS LPGPRs looked promising, but NXP’s guidance is thin and we don’t keep the battery-backed LP domain alive, so those values won’t survive many power cycles. Are there better options on LS1028A? Would using the user RAM byte in our external I2C RTC make sense? Or perhaps should I store it on eMMC? (we don't use raw NOR/NAND flash). That RTC I mentioned is already accessed in both U-Boot and Linux, so I’m wary of conflicts but can try it if you think it’s viable. Any suggestions would be much appreciated. Best regards Patryk

Question about SError exception routing

by Julius Werner

Hi, I have a sort of generic Arm architecture question that's not directly related to TF-A (other than that TF-A controls some of the registers involved in this decision), but I'm hoping that one of the experts here can still help me out or at least refer me to someone who can. I'm trying to figure out how exception routing for SError aborts works in EL2. Specifically, I have a bootloader (BL33) running in NS-EL2 and I want the "simple" setup that it manages all its own exceptions, the same way that an OS kernel normally manages all exceptions at EL1. I assumed that I could achieve that simply by installing exception handlers, unmasking all exceptions in PSTATE, and leaving all the special trap feature bits in the MSRs at 0 (disabled). This seems to work for synchronous exceptions and external aborts, but not for SErrors. Looking at the architecture reference manual (revision L.b), table D1-14 in section D1.3.6.3 (page D1-6114), I can see that my case is represented by the first line (all special trap bits 0), which shows that SErrors caused by EL0 and EL1 would be routed to EL1 as expected (though even when PSTATE.A is 1 which seems odd?), but SErrors caused by EL2 will get ignored and remain pending (with no regard to PSTATE.A). Instead, the "default" behavior I expect (aborts get routed to the EL that caused them if PSTATE.A is 0) seems to require me to enable SCTLR_EL2.NMEA. But if you're looking at the description of SCTLR_EL2.NMEA, it says that it controls whether PSTATE.A masks SError exceptions at EL2 (and that if it is 0, SError exceptions are not taken at EL2 if PSTATE.A == 1). Doesn't that imply that SError exceptions *are* taken at EL2 if PSTATE.A == 0? What does a control that seems to be about trapping masked aborts from a lower EL have to do with unmasked aborts from my current EL? Basically, I think what I'm asking is: is that table really correct as printed (some behavior we've observed seems to indicate it is), and if so, why? Why do SError exceptions seem to behave differently by default in EL1 and EL2 (in regards to unmasked exceptions taken from the same exception level)? Why does the PSTATE.A bit only seem to apply to EL0 and EL1, not EL2 and EL3, even for exceptions taken from the same level, when this peculiarity seems to not be mentioned anywhere else in the manual? Why do SError exceptions get treated so differently from external aborts in EL2/EL3, when in EL1 they seem to mostly count as the same? Is the current description of the NMEA bit in the SCTLR_EL2 register documentation really accurate, if it also seems to make fundamental changes to cases not really mentioned in that description? Is there any way for EL2 to only handle its own SError exceptions without interfering with EL1's exception handling when FEAT_DoubleFault2 is not implemented (other than flipping HCR_EL2.AMO on every EL2 entry/exit)? And am I the only one who finds this all incredibly inconsistent and confusing? I feel like I'm missing some critical insight in how you were meant to think about this to make it make sense, would appreciate any help in that regard! Thanks, Julius
