This\nseries wires it into U-Boot as an optional backend behind the existing\n'tpm2' command, alongside support for QEMU+swtpm, sandbox emulation, and\nreal Raspberry Pi 4 + Infineon SLB9672 hardware.\n\nBranch (full 14-commit history including the subtree squash + merge):\n https://github.com/aidangarske/u-boot wolftpm-v2-patches\n\nNote on the subtree commits omitted from this email thread:\n The branch above contains 14 commits; the email series is 12 patches.\n Two commits are deliberately not sent to the list:\n\n * \"Squashed 'lib/wolftpm/' content from commit 664db130d57\"\n - the parentless squash commit produced by `git subtree add`.\n Its diff is ~3.4MB / ~90k lines and would be rejected by the\n mailing list on size.\n * \"Merge commit 'd42fd7b146...' as 'lib/wolftpm'\"\n - the corresponding subtree merge commit. Merges have no patch\n form and are routinely omitted by `git format-patch`.\n\n Please pull from the branch above (or wolfssl/wolfTPM @ 664db130d57)\n to inspect the imported wolfTPM source. Subsequent updates will go\n via tools/update-subtree.sh, matching how mbedTLS, lwIP, and\n dts/upstream are maintained in tree.\n\nChanges since v2:\n - Replaced the lib/wolftpm git submodule with a git subtree import\n (squash + merge), matching the convention used for mbedTLS, lwIP,\n and dts/upstream. tools/update-subtree.sh is updated to know\n about the wolftpm subtree (path lib/wolftpm, upstream\n https://github.com/wolfssl/wolfTPM.git).\n [feedback: Ilias Apalodimas]\n - Reverted the changes to include/linux/byteorder/generic.h. The\n redefinition workaround for cpu_to_beXX / beXX_to_cpu now lives\n on the wolfTPM side: include/configs/user_settings.h pulls in\n <asm/byteorder.h> up front so U-Boot's macros are defined before\n wolfTPM's #ifndef-guarded fallbacks in tpm2_packet.h.\n [feedback: Ilias Apalodimas]\n\nTesting:\n - QEMU arm64 + swtpm Python test framework\n (./test/py/test.py --bd qemu_arm64 -k \"test_wolftpm and not ut_cmd\"):\n 19 passed, 2 skipped (matching doc/usage/cmd/wolftpm.rst).\n - Manual QEMU arm64 + swtpm walkthrough per\n doc/usage/cmd/wolftpm.rst section \"Building and Running wolfTPM\n with U-Boot using QEMU\": tpm2 help/info/autostart/startup/\n get_capability/pcr_read/pcr_print/caps all return expected output.\n - Raspberry Pi 4 + Infineon SLB9672 (real hardware): all wolfTPM\n cmd tests pass, including firmware update path.\n\nv2 thread:\n https://lore.kernel.org/u-boot/?q=PATCH+v2+tpm+wolfTPM\n\nAidan Garske (12):\n tpm: export tpm_show_device, tpm_set_device, and get_tpm\n include/hash: add SHA384 hash wrapper declaration for wolfTPM\n spi: add BCM2835/BCM2711 hardware SPI controller driver\n dts: add TPM device tree nodes for RPi4, QEMU, and sandbox\n tpm: add wolfTPM build rules and Kconfig\n tpm: add wolfTPM headers and SHA384 glue code\n tpm: add wolfTPM driver helpers and Kconfig options\n cmd: refactor tpm2 command into frontend/backend architecture\n tpm: add sandbox TPM SPI emulator\n test: add wolfTPM C unit tests and Python integration tests\n doc: add wolfTPM documentation\n configs: enable wolfTPM in rpi_4_defconfig\n\n--\n2.47.3" }
