    "content": "First there is a single big endian format defined in `formats.yaml`: RGB565_BE.\nHowever, while the yaml file specifies \"big_endian: true\", the python script\nlooks for a key named \"big-endian\". Causing `RGB565{,_BE}` both to be the same.\n\nSecond, the python script simply appends \" | DRM_FORMAT_BIG_ENDIAN\" to the\nfourcc of the format. However, there is no definition of that macro is\navailable in the only user, `formats.h.in`.\n\nFix the first one by checking for \"big_endian\" in the script as well, and\nfix the second one by defining a constant with the same value and using that.\n\nSigned-off-by: Barnabás Pőcze <barnabas.pocze@ideasonboard.com>\nFixes: 7c496f1c54dd58 (\"utils: gen-formats: Support big-endian DRM formats\")\n---\n include/libcamera/formats.h.in | 4 +++-\n utils/codegen/gen-formats.py   | 3 +--\n 2 files changed, 4 insertions(+), 3 deletions(-)",
