sl@0:  * __SECURITY_PLATSEC_ARCH__: Changes for platform security
sl@0:  *
sl@0:  * If this macro is defined, the represenation of TPtrC arrays is changed from
sl@0:  * using CPtrCArray to RArray<TPtrC>.  This is because CPtrCArray is supplied by
sl@0:  * bafl.dll, which is not trusted for TCB.  x509 needs to be trusted for TCB so
sl@0:  * it can be used by software install, hence this dependency was removed.
sl@0:  *
sl@0:  * This changes is implmented as a series of macros for the basic operations,
sl@0:  * to minimise the amount of conditional compilation.
