T398: Source cleanup for tool chain integration
This is a code cleanup to improve portability.
Specific issues addressed:
- Added type casts to (void *) here and there
- Changed non-standard \e escapes to \033
- Added cmake function to handle preinclude
- Changed a few Image$$ references to make use of the REGION_DECLARE
macro
- Reordered code slightly to avoid the need for a "void *rangeptr"
variable
- Changed compile time check typedef "err_msg" to avoid declaring
zero sized array, which is not standards compliant. It will now
either be -1 (error) or 1 (ok), not -1 and 0
- Reordered the *nfsptr_t typedef to make the cmse_nonsecure_call
standards compliant
- Added null tests to both secure and non_secure suites to avoid
defining zero length array. Also use this to find end of list
- Only define __stdout for ARMCLANG builds and conditionalize ns printf
output for ARMCLANG/GCC/IAR
- Cleaned up some enum type mismatches
- Changed non standard EINVAL error return to -1. The value was only
checked against 0 anyway
- Added type cast for conversion from float to int
Have tested with IAR, which starts and runs the idle thread. Changes
related to this is not included in this commit.
