[PATCH TF-A] fix(plat/rcar3): Fix RPC-IF device node name

by Geert Uytterhoeven

According to the Generic Names Recommendation in the Devicetree Specification Release v0.3, and the DT Bindings for the Renesas Reduced Pin Count Interface, the node name for a Renesas RPC-IF device should be "spi". The node name matters, as the node is enabled by passing a DT fragment from TF-A to subsequent software. Fix this by renaming the device nodes from "rpc" to "spi". Fixes: 12c75c8886a0ee69 ("feat(plat/rcar3): emit RPC status to DT fragment if RPC unlocked") Signed-off-by: Geert Uytterhoeven <geert+renesas(a)glider.be> --- Background: On Renesas R-Car Gen3 platforms, the SPI Multi I/O Bus Controllers (RPC-IF) provide access to HyperFlash or QSPI storage. On production systems, they are typically locked by the TF-A firmware, unless TF-A is built with RCAR_RPC_HYPERFLASH_LOCKED=0. When unlocked, TF-A communicates this to subsequent software by passing a DT fragment that sets the "status" property of the RPC-IF device node to "okay". Unfortunately there are several issues preventing this from working all the way to Linux: 1. TF-A (and U-Boot on the receiving side) uses a device node name that does not conform to the DT specification nor the DT bindings for RPC-IF, 2. While U-Boot receives the RPC-IF enablement from TF-A, it does not propagate it to Linux yet, 3. The DTS files that are part of Linux do not have RPC HyperFlash support yet. This patch takes care of the first issue in TF-A. The related patches for U-Boot are [1]. Patches to enable RPC-IF support in Linux are available at [2]. Thanks for your comments!

[Question] fix(security): apply SMCCC_ARCH_WORKAROUND_3 to A73/A75/A72/A57

by JY Ho (何駿彥)

Dear Sirs, I’m TF-A developer of MediaTek and have a situation of CVE patch (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298) with CA73. In CA73 platform with 64-bit TF-A v2.4 and 64-bit OP-TEE v3.16, system will occur halt during boot flow after we applied fix(security): apply SMCCC_ARCH_WORKAROUND_3 to A73/A75/A72/A57<https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298>. We used ICE to trace boot flow step by step, and found S-EL1 will ask EL3 its SMC_VERSION. In the fastcall, TF-A will execute wa_cve_2017_5715_bpiall_vbar()<https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298/11/lib…> which back up some setting and switch processor from AArch-64 to AArch-32 and does BPIALL<https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298/11/lib…>. But AArch32 cannot access and run over than 4G bus address without LPAE. (Suppose the TF-A and OP-TEE are locate on over than 4G bus address.) Maybe can we replace AArch32_stub with IC IALLU ? Or add LPAE setting before do AArch32_stub? (I don’t know it make sense or not) Thank you. JY
