fw_cfg: Add support for LoongArch architecture

2026-06-10T06:17:00+00:00

Qemu fw_cfg support was missing for LoongArch, which made some functions unusable in virtual machines. So add the missing LoongArch defines. Signed-off-by: Huacai Chen Signed-off-by: Michael S. Tsirkin Message-ID: <20260529140559.1775511-1-chenhuacai@loongson.cn>

firmware: raspberrypi: Change dependency to ARCH_BCM2835 and COMPILE_TEST

2026-05-06T19:35:53+00:00

The Raspberry Pi firmware driver has no compile dependencies on the BCM2835 mailbox driver. It's just a indirect runtime dependency: the driver only works on a Raspberry Pi. Change the dependency from BCM2835_MBOX to ARCH_BCM2835. Also allow compile tests. This allows drivers that have build time dependencies on this firmware driver to be compile tested as well. More dependencies are added to account for build time dependencies: - depends on MAILBOX for mailbox API (not stubbed) usage - depends on ARM || ARM64 for dsb() usage Also make it built by default if ARCH_BCM2835, since many functions will not work without this firmware driver.

firmware: SDEI: Allow sdei initialization without ACPI_APEI_GHES

2025-05-08T12:35:22+00:00

SDEI usually initialize with the ACPI table, but on platforms where ACPI is not used, the SDEI feature can still be used to handle specific firmware calls or other customized purposes. Therefore, it is not necessary for ARM_SDE_INTERFACE to depend on ACPI_APEI_GHES. In commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in acpi_init()"), to make APEI ready earlier, sdei_init was moved into acpi_ghes_init instead of being a standalone initcall, adding ACPI_APEI_GHES dependency to ARM_SDE_INTERFACE. This restricts the flexibility and usability of SDEI. This patch corrects the dependency in Kconfig and splits sdei_init() into two separate functions: sdei_init() and acpi_sdei_init(). sdei_init() will be called by arch_initcall and will only initialize the platform driver, while acpi_sdei_init() will initialize the device from acpi_ghes_init() when ACPI is ready. This allows the initialization of SDEI without ACPI_APEI_GHES enabled.

firmware: turris-mox-rwtm: Add support for ECDSA signatures with HW private key

2025-03-20T16:56:57+00:00

Add support for digital message signing with the private key stored in the rWTM secure coprocessor. Turris Mox devices have an ECDSA private key generated and burned into rWTM eFuses when manufactured. This private key is not readable from the rWTM, but rWTM firmware allows for signing messages with it and retrieving the public key. This is exposed to userspace via the keyctl API. User can find the key by either looking at /proc/keys or listing the keyring: $ cat /proc/keys 0240b221 ... keyring .turris-signing-keys: 1 34ff9ac9 ... turris-si Turris MOX SN 0000000D30000005 rWTM ECDSA ke... $ keyctl rlist %:.turris-signing-keys 889166537 To get the public key: $ keyctl read 889166537 67 bytes of data in key: 0201a05c 1a79242b 13f2fc02 b48ffdbb 6ee8d5ba 812d6784 5f04f302 c0894d3e b93474f9 46235777 5c926fb4 cce89b50 88cf5d10 c07fd9c5 fdcea257 3d8f1c33 1bf826 To sign a message: $ dd if=/dev/urandom of=msg_to_sign bs=64 count=1 $ keyctl pkey_sign 889166537 0 msg_to_sign >signature Signed-off-by: Marek Behún Signed-off-by: Arnd Bergmann

A bit older ARM64 designs, like Exynos8895 use older USI v1 block. 2. Add Exynos ACPM (Alive Clock and Power Manager) protocol driver for Google GS101 SoC. ACPM protocol allows communication between the power management firmware and other embedded processors. 3. Exynos2200: Add PMU, ChipID and SYSREG Devicetree bindings. 4.
