Existing users (kaslrseed, and ARMv8 sec firmware) have been updated to use this common API. New functionality has been introduced to populate the kaslr using the RNG. This can be enabled with CONFIG_RNG_TPM_SEED. changes in v3: - Populate with RNG device instead of TPM device (this is a more generic solution) - Use event spy to do the FDT fixup - fix compile error for sandbox for !OFNODE_MULTI_TREE changes in v2: - fdt_fixup_kaslr_seed() uses the ofnode API - Add root_ofnode_from_fdt() to get the root node from an FDT and perform error checking on the oftree - add comments to exported functions - Add error checking in image_setup_libfdt() for return from fdt_tpm_kaslr_seed() - uclass_get_device() -> uclass_first_device_err() - Change default config for OFNODE_MULTI_TREE (y if !OF_LIVE) Dhananjay Phadke (2): fdt: common API to populate kaslr seed fdt: kaslr seed from RNG device Sean Edmond (3): cmd: kaslrseed: Use common API to fixup FDT dm: core: Modify default for OFNODE_MULTI_TREE fdt: Fix compile error for !OFNODE_MULTI_TREE arch/arm/cpu/armv8/sec_firmware.c | 39 ++++++++-------------- cmd/kaslrseed.c | 22 +++++-------- common/fdt_support.c | 55 +++++++++++++++++++++++++++++++ drivers/core/Kconfig | 2 +- drivers/core/ofnode.c | 29 ++++++++++++---- include/dm/ofnode.h | 12 +++++++ include/fdt_support.h | 9 +++++ lib/Kconfig | 7 ++++ 8 files changed, 129 insertions(+), 46 deletions(-) -- 2.40.0
