Signed-off-by: Dorota Czaplejewicz Reviewed-by: Philipp Zabel --- Hello, This patch series attempts to separate image format handling between devices in the i.MX5/6 and i.MX7/8 families. The first patch in the series implements the suggestion I received from Philipp Zabel as feedback to the previous series. The last 3 could in principle be submitted as a single patch, but I opted for minimal changes, for reviewing clarity. The last patch is the core of the change, where i.MX5/6 uses the old code path, and i.MX7/8 uses a slightly redacted copy of it. I have fairly limited experience with the parameters that go into determining the format, so I opted only to adjust the part I have tested: the rounding.
