ramfunc region is copied into RAM from FLASH region during XIP init. We copy from the loadaddr of the region, and were previously loading to the symbol __ramfunc_start. This is incorrect when using an MPU with alignment requirements, as the __ramfunc_start symbol may have padding placed before it in the region. The __ramfunc_start symbol still needs to be aligned in order to be used by the MPU though, so define a new symbol __ramfunc_region_start, and use that symbol when copying the __ramfunc region from FLASH to RAM. Fixes zephyrproject-rtos#75296 Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com> (cherry picked from commit 6023d6a)
Remove usage of ld-specific ADDR function within the cmake linker generator scripting. Since the linker generator scripting doesn't support MPUs, we can simply set the __ramfunc_region_start symbol to be equal to __ramfunc_start Fixes zephyrproject-rtos#87200 Signed-off-by: Daniel DeGrasse <ddegrasse@tenstorrent.com> (cherry picked from commit b84076a)
