lib: Allow crc16 code to be dropped

2025-02-03T22:00:42Z

This code is not necessarily needed in VPL, even if SPL uses it, so adjust the rules to allow it to be dropped. Do the same for the hash API. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

tpm: add wrapper and helper APIs for PCR allocate

2025-01-28T06:58:41Z

Add PCR allocate wrapper APIs for using in tcg2 protocol. The wrapper proceeds a PCR allocate command, followed by a shutdown command. A system boot is required after two commands since TPM device needs a HW reset to activate the new algorithms config. Also, a helper function is included to determine the new bank mask for PCR allocation by combining the status of current active, supported and eventlog bank masks. A new kconfig is created. PCR allocate and system reboot only happens when the kconfig is selected, otherwise just exit with errors. Signed-off-by: Raymond Mao Reviewed-by: Ilias Apalodimas Signed-off-by: Ilias Apalodimas

Merge patch series "upl: Prerequite patches for updated spec"

2025-01-22T23:08:47Z

Simon Glass says: The current UPL spec[1] has been tidied up and improved over the last year, since U-Boot's original UPL support was written. This series includes some prerequisite patches needed for the real UPL patches. It is split from [2] [1] https://github.com/UniversalPayload/spec/tree/3f1450d [2] https://patchwork.ozlabs.org/project/uboot/list/?series=438574&state=* Link: https://lore.kernel.org/r/20250111000029.245022-1-sjg@chromium.org

emulation: Use bloblist to hold tables

2025-01-22T23:08:23Z

QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot copies out the SMBIOS tables but points directly to the ACPI ones. The ACPI tables are not aligned on a 4KB boundary, which means that UPL cannot use them directly, since it uses a reserved-memory node for the tables and that it assumed (by EDK2) to be 4KB-aligned. On x86, QEMU provides the tables in a mapped memory region and U-Boot makes use of these directly, thus making it difficult to use any common code. Adjust the logic to fit within the existing table-generation code. Use a bloblist always and ensure that the ACPI tables is placed in an aligned region. Set a size of 8K for QEMU. This does not actually put all the tables in one place, for QEMU, since it currently adds a pointer to the tables in QFW. On ARM, enable bloblist so that SMBIOS tables can be added to the bloblist.

Merge patch series "SMBIOS improvements"

2025-01-14T20:29:49Z

Raymond Mao says: Motivations for changes: Current SMBIOS library and command-line tool is not fully matching with the requirements: 1. Missing support for other mandatory types (#7, #9, #16, #17, #19). 2. Only a few platforms support SMBIOS node from the device tree. 3. Values of some fields are hardcoded in the library other than fetching from the device hardware. 4. Embedded data with dynamic length is not supported (E.g. Contained Object Handles in Type #2 and Contained Elements in Type #3) Changes: 1. Refactor the SMBIOS library and command-line tool to better align with the SMBIOS spec. 2. Create an arch-specific driver for all aarch64-based platforms to fetch SMBIOS private data from the device hardware (processor and cache). 3. Create a sysinfo driver to poppulate platform SMBIOS private data. 4. Add generic SMBIOS DTS file for arm64 platforms for those common strings and values which cannot be retrieved from the system registers. Vendors can create their own SMBIOS node using this as an example. For those boards without SMBIOS nodes, this DTS file can be included to have a generic SMBIOS information of the system. 5. Add support for Type #7 (Cache Information) and link its handles to Type #4. 6. To minimize size-growth for those platforms which have not sufficient ROM spaces or the platforms which don't need detailed SMBIOS information, new added fields are only being built when kconfig GENERATE_SMBIOS_TABLE_VERBOSE is selected. Once this patch is acceptted, subsequent patch sets will add other missing types (#9, #16, #17, #19). Tests: To test this with QEMU arm64, please follow the guide on dt_qemu.rst to get a merged DT to run with. ``` qemu-system-aarch64 -machine virt -machine dumpdtb=qemu.dtb cat <(dtc -I dtb qemu.dtb) <(dtc -I dtb ./dts/dt.dtb | grep -v /dts-v1/) \ | dtc - -o merged.dtb qemu-system-aarch64 -machine virt -nographic -bios u-boot.bin \ -dtb merged.dtb ``` Link: https://lore.kernel.org/r/20241206225438.13866-1-raymond.mao@linaro.org

smbios: Refactor smbios library

2025-01-14T20:29:29Z

Current smbios library does not fully match to the specification. It hardcodes values instead of exposing values from the device. It does not reserve the space to support dynamic length for contained object handles or elements and misses the handling of a few of fields. The refactoring of this patch includes: 1. Expose values from device via sysinfo interface. 2. Replace smbios_add_prop with smbios_add_prop_si to allow getting string values from sysinfo. 3. Add smbios_get_val_si to get values from sysinfo or device tree. 4. Use sysinfo_get_data to get data area. 5. Reserve the space of contained object handles and elements. 6. Miscellaneous fixes in smbios. Signed-off-by: Raymond Mao
