+/* The Durandal-v1 uses an STM32H743II has 2048Kb of main FLASH memory.
+ * The flash memory is partitioned into a User Flash memory and a System
+ * Flash memory. Each of these memories has two banks:
+ *
+ *   1) User Flash memory:
+ *
+ *      Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb each
+ *      Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb each
+ *
+ *   2) System Flash memory:
+ *
+ *      Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ *      Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ *   3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743II, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash memory at 0x0800:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * The Durandal has a Swtich on board, the BOOT0 pin is at ground so by default,
+ * the STM32 will boot to address 0x0800:0000 in FLASH unless the swiutch is
+ * drepresed, then the boot will be from 0x1FF0:0000
+ *
+ * The STM32H743ZI also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ *   1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ *      0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
+ *
+ *      1.1) 128Kb of DTCM-RAM beginning at address 0x2000:0000
+ *
+ *           The DTCM-RAM is organized as 2 x 64Kb DTCM-RAMs on 2 x 32 bit
+ *           DTCM ports. The DTCM-RAM could be used for critical real-time
+ *           data, such as interrupt service routines or stack / heap memory.
+ *           Both DTCM-RAMs can be used in parallel (for load/store operations)
+ *           thanks to the Cortex-M7 dual issue capability.
+ *
+ *      1.2)  64Kb of ITCM-RAM beginning at address 0x0000:0000
+ *
+ *           This RAM is connected to ITCM 64-bit interface designed for
+ *           execution of critical real-times routines by the CPU.
+ *
+ *   2) AXI SRAM (D1 domain) accessible by all system masters except BDMA
+ *      through D1 domain AXI bus matrix
+ *
+ *      2.1) 512Kb of SRAM beginning at address 0x2400:0000
+ *
+ *   3) AHB SRAM (D2 domain) accessible by all system masters except BDMA
+ *      through D2 domain AHB bus matrix
+ *
+ *      3.1) 128Kb of SRAM1 beginning at address 0x3000:0000
+ *      3.2) 128Kb of SRAM2 beginning at address 0x3002:0000
+ *      3.3)  32Kb of SRAM3 beginning at address 0x3004:0000
+ *
+ *      SRAM1 - SRAM3 are one contiguous block: 288Kb at address 0x3000:0000
+ *
+ *   4) AHB SRAM (D3 domain) accessible by most of system masters
+ *      through D3 domain AHB bus matrix
+ *
+ *      4.1)  64Kb of SRAM4 beginning at address 0x3800:0000
+ *      4.1)   4Kb of backup RAM beginning at address 0x3880:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.

+/* The Durandal-v1 uses an STM32H743II has 2048Kb of main FLASH memory.
+ * The flash memory is partitioned into a User Flash memory and a System
+ * Flash memory. Each of these memories has two banks:
+ *
+ *   1) User Flash memory:
+ *
+ *      Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb each
+ *      Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb each
+ *
+ *   2) System Flash memory:
+ *
+ *      Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ *      Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ *   3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743II, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash memory at 0x0800:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * The Durandal has a Swtich on board, the BOOT0 pin is at ground so by default,
+ * the STM32 will boot to address 0x0800:0000 in FLASH unless the swiutch is
+ * drepresed, then the boot will be from 0x1FF0:0000
+ *
+ * The STM32H743ZI also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ *   1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with

+/* The board uses an STM32H743II and has 2048Kb of main FLASH memory.
+ * The flash memory is partitioned into a User Flash memory and a System
+ * Flash memory. Each of these memories has two banks:
+ *
+ *   1) User Flash memory:
+ *
+ *      Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb each
+ *      Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb each
+ *
+ *   2) System Flash memory:
+ *
+ *      Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ *      Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ *   3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743II, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash memory at 0x0800:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * There's a switch on board, the BOOT0 pin is at ground so by default,
+ * the STM32 will boot to address 0x0800:0000 in FLASH unless the switch is
+ * drepresed, then the boot will be from 0x1FF0:0000
+ *
+ * The STM32H743ZI also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ *   1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ *      0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
