****************************************************************************/
/* The STM32H745ZI 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 STM32H745ZI, 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
*
* TODO: Check next paragraph with nucleo schematics
*
* NuttX does not modify these option bytes. On the unmodified
* STM32H745I-DISCO board, the BOOT0 pin is at ground so by default, the
* STM32 will boot to address 0x0800:0000 in FLASH.
*
* The STM32H745ZI 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.
