 *  Abstract    : Linker script for STM32H735VGTx Device from stm32h7 series
 *                      1024Kbytes ROM
 *                      560Kbytes RAM
 *
 *            Set heap size, stack size and stack location according
 *            to application requirements.
 *
 *            Set memory bank area and size if external memory is used
 *  Note: The original linker script is in the file linker_flash_old
