/* c2000_stdint.h
*
* Force-included (--preinclude) for the TI C2000 C28x (ARCH=C2000) build.
*
* The C28x is word-addressed with CHAR_BIT==16 and has NO 8-bit integer type,
* so ISO <stdint.h> correctly does not define int8_t/uint8_t on this target.
* wolfBoot (and TI's own driverlib hw_types.h) represents an octet in a 16-bit
* cell, so provide the exact-width 8-bit aliases as 16-bit types. When a
* translation unit also pulls in driverlib's hw_types.h, its identical
* typedefs produce diagnostic #303, suppressed for this arch in arch.mk.
