This series add support for MBR partition tables\nto the protocol, making U-Boot compatible with systems that require a\nlegacy MBR table.\n\nThis is a second version of the patches that addresses issues pointed out\nby Heinrich Schuchardt (thanks!). The first version can be found here:\n\nhttps://lists.denx.de/pipermail/u-boot/2025-June/592644.html\n\nPatches #1 to #3 are preparatory changes to remove duplicated definitions\nof data structures to store the MBR records.\n\nPatch #4 just documents the part_get_info_extended() helper function and\npatch #5 refactors this function to also optionally return the MBR record data.\n\nPatch #6 adds the MBR support to the EFI_PARTITION_INFO_PROTOCOL implementation\nand patch #7 enhances the protocol selftest, to check that the partition record\ndata is correctly filled.\n\nChanges in v2:\n- Add Tom Rini Rini's Reviewed-by tags to patches 1-3.\n- Document part_get_info_extended() helper function.\n- Split partition library and EFI changes in separate patches.\n- Add static MBR data in EFI block device test and compare the queried data.\n\nJavier Martinez Canillas (7):\n disk: part_dos: Move header to the main include directory\n disk: part_dos: Align dos_partition_t with struct partition\n disk: part_efi: Remove redundant struct partition definition\n disk: part_dos: Document part_get_info_extended() helper function\n disk: part_dos: Refactor to allow retrieving raw MBR partition data\n efi_loader: disk: Extend EFI_PARTITION_INFO_PROTOCOL to support MBR\n efi_selftest: Enhance MBR test for PARTITION_INFO_PROTOCOL\n\n disk/part_dos.c | 91 +++++++++++++-------\n disk/part_efi.c | 4 +-\n include/part.h | 14 +++\n {disk => include}/part_dos.h | 6 +-\n include/part_efi.h | 19 +---\n lib/efi_loader/efi_disk.c | 9 +-\n lib/efi_selftest/efi_selftest_block_device.c | 26 ++++++\n 7 files changed, 113 insertions(+), 56 deletions(-)\n rename {disk => include}/part_dos.h (87%)" }
