bb07377458 Merge pull request #7935 from AgathiyanB/add-enum-casts
Add type casts for integer and enum types
2023-07-26 11:27:27 +02:00
10b6775aeb Add enum type casts in lmots.c and lms.c
The IAR compiler throws an error when trying to assign an int to an enum
so these casts have been added.

2be8c63af7 Create psa_util_internal.h
Most functions in psa_util.h are going to end up there (except those
that can be static in one file), but I wanted to have separate commits
for file creation and moving code around, so for now the new file's
pretty empty but that will change in the next few commits.

0064484a70 Optimize error translation code size
Introducing an intermediate function
saves code size that's otherwise taken by excessive,
repeated arguments in each place that
was translating errors.

8a045ce5e6 Unify PSA to Mbed TLS error translation
Move all error translation utilities to psa_util.c.
Introduce macros and functions to avoid having
a local copy of the error translating function in
each place.
Identify overlapping errors and introduce a
generic function.
Provide a single macro for all error translations
(unless one file needs a couple of different ones).
