Modify the function to take only two arguments where the second one is to be a path to a directory storing partial dts. This will help reusing this function in the future to perform sanity checks on partial dts that do not originate from a repository. Modify compile_merge_partial_dts to take this change into account.

With the recent changes done in the lopper, we can use it to generate partial dts automatically (to some extent as this is still an early support). Introduce LOPPER_PATH option to specify a path to a lopper.py script, that if set, will invoke lopper to generate partial dts for the passthrough devices specified in DOMU_PASSTHROUGH_PATHS. Introduce LOPPER_CMD option to specify custom command line arguments (if needed) for lopper's extract assist. Example usage: LOPPER_PATH="/home/user/lopper/lopper.py" DOMU_PASSTHROUGH_PATHS[0]="/axi/spi@ff0f0000 /axi/serial@ff010000" Signed-off-by: Michal Orzel --- README.md | 22 ++++++++++++-- scripts/common | 64 ++++++++++++++++++++++++++++++---------- scripts/uboot-script-gen | 17 +++++++++-- 3 files changed, 83 insertions(+), 20 deletions(-) diff --git a/README.md b/README.md index da9ba788a3bf..aaee0939b589 100644 --- a/README.md +++ b/README.md @@ -128,6 +128,19 @@ Where: - DT_OVERLAY[number] specifies the path to the hosts device tree overlays to be added at boot time in u-boot +- LOPPER_PATH specifies the path to lopper.py script.
