Assignee: Christian Mauderer
## Summary
The warning below is for a missing extern declaration of _dcp_hash_ctx_t_size_.
Unfortunately, grep -r shows that this symbol does not appear in the RTEMS
source tree except in this one BUILD_ASSURE macro.
```
../../../bsps/arm/imxrt/mcux-sdk/drivers/dcp/fsl_dcp.c: In function
'DCP_HASH_Init':
../../../bsps/arm/imxrt/mcux-sdk/drivers/dcp/fsl_dcp.c:1214:77: warning: nested
extern declaration of 'dcp_hash_ctx_t_size' [-Wnested-externs]
1214 | BUILD_ASSURE(sizeof(dcp_hash_ctx_t) >=
sizeof(dcp_hash_ctx_internal_t), dcp_hash_ctx_t_size);
|
^~~~~~~~~~~~~~~~~~~
../../../bsps/arm/imxrt/mcux-sdk/drivers/dcp/fsl_dcp.c:24:49: note: in
definition of macro 'BUILD_ASSURE'
24 | #define BUILD_ASSURE(condition, msg) extern int msg[1 - 2 *
(!(condition))] __attribute__((unused))
|
```
The configuration was:
```
[arm/imxrt1052]
BUILD_SAMPLES=True
BUILD_TESTS=True
RTEMS_DEBUG=True
RTEMS_POSIX=False
```
