Start address of Non-Secure Callable section.

Notes: - The default value (i.e. when the user does not configure the option explicitly) instructs the linker script to place the Non-Secure Callable section, automatically, inside the .text area. - Certain requirements/restrictions may apply regarding the size and the alignment of the starting address for a Non-Secure Callable section, depending on the available security attribution unit (SAU or IDAU) for a given SOC.
