The routine for transferring the program from ROM to RAM should be created within main.c.
note: Locating the .textu1 and .textu2 sections preceding a .rodata section with (for example)
no LMA specified will result in positioning the .rodata section behind the end VMA address of
the .textu2 section. Do not locate any VMA-only sections behind LMA ≠ VMA sections.
