As I proposed and discussed in [1] and [2], I have made a couple of improvements on the current implementation of capsule update in this patch set.
* add signing feature to mkeficapsule * add "--guid" option to mkeficapsule * add man page of mkeficapsule * update uefi document regarding capsule update * revise pytests

Prerequisite patches ==================== None
Test ==== * locally passed the pytest which is included in this patch series on sandbox built. (CONFIG_EFI_CAPSULE_AUTHENTICATE should explicitly be turned on in order to exercise the authentication code.)
Changes ======= v9 (Jan 18, 2022) * rebased on v2022.01 * print the output messages to stderr (patch#1,#2, #4 and #6) * use SIZE_MAX instead of (u32)!0U (patch#2) * revise and re-format the man page of mkeficapsule (patch#5) * add "code-block:: console" directives for command line examples in a ReST document (patch#6) * describe the case when a trailing '/' in EFITOOLS_PATH is needed (patch#7) * describe UUID data as a binary rather than a string (patch#8) * drop fdtsig.sh-related patches (patch#12,#13 in v8)
v8 (Dec 20, 2021) * rebase on v2022.01-rc3 * move the definition of CONFIG_TOOLS_MKEFICAPSULE to a proper patch (patch#2)
v7 (Nov 16, 2021) * rebased on pre-v2022.01-rc2 * drop already-merged patch * check for a size of firmware binary file (patch#1) * enable mkeficapsule in tools-only_defconfig (patch#2) * define eficapsule.h and include it from mkeficapsule (patch#3) Hopefully, the tool can now compile on non-linux host.
v6 (Nov 02, 2021) * rebased on pre-v2022.01-rc1 * add patch#2 to rework/refactor the code for better readability (patch#2) * use exit(EXIT_SUCCESS/FAILURE) (patch#3) * truncate >80chars lines in pytest scripts (patch#6)
v5 (Oct 27, 2021) * rebased on pre-v2022.01-rc1 (WIP/26Oct2021) * drop already-merged patches * drop __weak from efi_get_public_key_data() (patch#1) * describe the format of public key node in device tree (patch#4) * re-order patches by grouping closely-related patches (patch#6-8) * modify pytest to make the test results correctly verified either with or without CONFIG_EFI_CAPSULE_AUTHENTICATE (patch#9) * add RFCs for embedding public keys during the build process (patch#10,11)
v4 (Oct 7, 2021) * rebased on v2021.10 * align with "Revert "efi_capsule: Move signature from DTB to .rodata"" * add more missing *revert* commits (patch#1,#2,#3) * add fdtsig.sh, replacing dtb support in mkeficapsule (patch#4) * update/revise the man/uefi doc (patch#6,#7) * fix a bug in parsing guid string (patch#8) * add a test for "--guid" option (patch#10) * use dtb-based authentication test as done in v1 (patch#11)
v3 (Aug 31, 2021) * rebased on v2021.10-rc3 * remove pytest-related patches * add function descriptions in mkeficapsule.c * correct format specifiers in printf() * let main() return 0 or -1 only * update doc/develop/uefi/uefi.rst for syntax change of mkeficapsule
v2 (July 28, 2021) * rebased on v2021.10-rc* * removed dependency on target's configuration * removed fdtsig.sh and others * add man page * update the UEFI document * add dedicate defconfig for testing on sandbox * add gitlab CI support * add "--guid" option to mkeficapsule (yet rather RFC)
Initial release (May 12, 2021) * based on v2021.07-rc2
