				1059	Execute-In-Place allows the kernel to run from non-volatile storage

				1062	to RAM. Read-write sections, such as the data section and stack,
				1063	are still copied to RAM. The XIP kernel is not compressed since

				1065	store it. The flash address used to link the kernel object files,
