debug: tracing: Add Segger RTT linker section options
Allows optionally placing Segger RTT data either in a specific linker section that is located at RAM start, or in a specific linker section defined by a memory region in DTS, as third and fourth alternative to the DTCM section or the default data section. This is useful to share the fixed address for different programs, typically bootloader and application, and have seamless logging. Signed-off-by: Giancarlo Stasi <[email protected]>
