update:
CMakeLists.txt
Make.defs
Kconfig
It allows the same version of SystemView target sources to be used for CMake and Make, to avoid discrepancies in the future.

we are using segger RTT protocol over shared memory for two core log/trace: one is NuttX another Linux/Windows. But the base address of shared memory can only be known at runtime, so we change SEGGER_RTT_UNCACHED_OFF from macro to global variable, and update to the correct g_segger_offset after the shared memory is initialized by:
g_segger_offset = (uintptr_t)ishmem - (uintptr_t)&_SEGGER_RTT;

usage:
1. Connect Jlink, start JLinkGDBServer
JLinkGDBServer -if SWD -device stm32h743zi -speed 16000
2. Listen to the RTT port data and forward it to the virtual serial port
sudo socat -d -d PTY,link=/dev/ttyRTT0,raw,ignoreeof TCP:127.0.0.1:19021,reuseaddr
3. Read serial data
minicom -D /dev/ttyRTT0
