based on hardware parameters detected from SMEM.\n\nQualcomm fit based DTB format is documented in [1]\nThe fit image contains only DTB, while the kernel will be part of UKI image.\n\nThe implementation consists of three parts:\n\n1. SMEM cache infrastructure: Provides cached access to commonly\n used SMEM data (socinfo, RAM partitions) to avoid redundant\n lookups during boot. Includes socinfo header from Linux kernel\n for SoC identification.\n\n2. FIT multi-DTB selection: Implements the core selection logic\n that reads hardware parameters from SMEM, parses metadata DTB,\n matches FIT configurations, and loads the selected DTB with\n overlays. Integrates with EFI boot flow by setting fdt_addr.\n\n3. mkimage: add fatfs image type for FAT partition images\n Added fatimage.c handler that uses mkfs.vfat and mcopy to create\n FAT images from a directory.\n\n[1] https://github.com/qualcomm-linux/qcom-dtb-metadata/blob/main/Documentation.md\n\n---\nChanges in v3:\n1. Runtime IMEM address lookup via DT: Removed CONFIG_QCOM_IMEM_SIZE Kconfig option.\n Added qcom_imem_table[] mapping SoC compatible strings to IMEM addresses.\n\n2. Split SoC version sources: SoC hardware version now read from TCSR register via\n qcom_read_tcsr_soc_version(). The soc_info->plat_ver from SMEM is stored separately\n as board_version. Added socver and boardrev metadata node matching for finer-grained DTB selection.\n\n3. qcom_load_fit_image() returns int: Changed return type from efi_status_t to int,\n returning standard Linux error codes for consistency with the rest of the driver.\n\n4. Code cleanup: strtok() replaced with strsep(); memcpy + manual null-termination replaced with strlcpy();\n DDR thresholds use SZ_* macros; compatible matching and FDT loading extracted into dedicated helpers.\n\n5. image: add IH_TYPE_FATFS image type: Added new fatfs image type to represent a raw FAT\n filesystem partition image, registered in the image type lookup table.\n\n6. mkimage: add fatfs image type for FAT partition images: Added fatimage.c handler that\n uses mkfs.vfat and mcopy to create FAT images from a directory.\n New --fat-extra-space, --fat-type, --fat-volume-id, --fat-mkfs-opts long options added\n to mkimage.\n\n7. doc: document mkimage fatfs type and Qualcomm multi-DTB: Updated 'doc/mkimage.1' for the new\n fatfs type and options. Added 'doc/board/qualcomm/multi_dtb.rst' covering FIT ITS configuration,\n QCOM metadata format, socver/boardrev guidelines, and image creation steps.\n\nLink to v2:\nhttps://lore.kernel.org/u-boot/20260129184817.224101-1-aswin.murugan@oss.qualcomm.com/\n\nChanges in v2:\n- In v1, a combined DTB format was used for multi-DTB support. Based on\n feedback, v2 implements FIT-based DTB selection instead.\n- Link to v1: https://lore.kernel.org/all/20260106122134.2047864-1-aswin.murugan@oss.qualcomm.com/\n\nAswin Murugan (7):\n mach-snapdragon: Add generic SMEM cache infrastructure\n mach-snapdragon: Add FIT multi-DTB selection support\n configs: snapdragon: Enable FIT multi-DTB and configure IMEM\n image: add IH_TYPE_FATFS image type\n mkimage: add fatfs image type for FAT partition images\n doc: document mkimage fatfs type and Qualcomm multi-DTB\n mach-snapdragon: Reorder header includes\n\n arch/arm/mach-snapdragon/Kconfig | 8 +\n arch/arm/mach-snapdragon/Makefile | 1 +\n arch/arm/mach-snapdragon/board.c | 123 +-\n arch/arm/mach-snapdragon/qcom-priv.h | 24 +\n arch/arm/mach-snapdragon/qcom_fit_multidtb.c | 1103 ++++++++++++++++++\n arch/arm/mach-snapdragon/qcom_fit_multidtb.h | 189 +++\n arch/arm/mach-snapdragon/rampart.h | 225 ++++\n boot/image.c | 1 +\n configs/qcom_defconfig | 2 +\n doc/board/qualcomm/index.rst | 1 +\n doc/board/qualcomm/multi_dtb.rst | 352 ++++++\n doc/mkimage.1 | 103 ++\n include/image.h | 1 +\n include/soc/qcom/socinfo.h | 114 ++\n tools/Makefile | 1 +\n tools/fatimage.c | 495 ++++++++\n tools/fatimage.h | 25 +\n tools/mkimage.c | 21 +\n tools/mkimage.h | 15 +\n 19 files changed, 2793 insertions(+), 11 deletions(-)\n create mode 100644 arch/arm/mach-snapdragon/qcom_fit_multidtb.c\n create mode 100644 arch/arm/mach-snapdragon/qcom_fit_multidtb.h\n create mode 100644 arch/arm/mach-snapdragon/rampart.h\n create mode 100644 doc/board/qualcomm/multi_dtb.rst\n create mode 100644 include/soc/qcom/socinfo.h\n create mode 100644 tools/fatimage.c\n create mode 100644 tools/fatimage.h"}
