/* The STM32F407VG has 1024Kb of FLASH beginning at address 0x0800:0000 and
* 192Kb of SRAM. SRAM is split up into three blocks:
*
* 1) 112KB of SRAM beginning at address 0x2000:0000
* 2) 16KB of SRAM beginning at address 0x2001:c000
* 3) 64KB of CCM SRAM beginning at address 0x1000:0000
*
* 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.
*
* For MPU support, the kernel-mode NuttX section is assumed to be 128Kb of
* FLASH and 4Kb of SRAM. That is an excessive amount for the kernel which
* should fit into 64KB and, of course, can be optimized as needed (See
* also configs/clicker2-stm32/scripts/kernel-space.ld). Allowing the
* additional does permit addition debug instrumentation to be added to the
* kernel space without overflowing the partition.
*
* Alignment of the user space FLASH partition is also a critical factor:
* The user space FLASH partition will be spanned with a single region of
* size 2**n bytes. The alignment of the user-space region must be the same.
* As a consequence, as the user-space increases in size, the alignmment
* requirement also increases.
*
* This alignment requirement means that the largest user space FLASH region
* you can have will be 512KB at it would have to be positioned at
* 0x08800000. If you change this address, don't forget to change the
* CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
* the check in kernel/userspace.c.
*
* For the same reasons, the maximum size of the SRAM mapping is limited to
* 4KB. Both of these alignment limitations could be reduced by using
* multiple regions to map the FLASH/SDRAM range or perhaps with some
* clever use of subregions.
*
* A detailed memory map for the 112KB SRAM region is as follows:
*
* 0x20000 0000: Kernel .data region. Typical size: 0.1KB
* ------- ---- Kernel .bss region. Typical size: 1.8KB
* 0x20000 0800: Kernel IDLE thread stack (approximate). Size is
* determined by CONFIG_IDLETHREAD_STACKSIZE and
* adjustments for alignment. Typical is 1KB.
* ------- ---- Padded to 4KB
* 0x20000 1000: User .data region. Size is variable.
* ------- ---- User .bss region Size is variable.
* 0x20000 2000: Beginning of kernel heap. Size determined by
* CONFIG_MM_KERNEL_HEAPSIZE.
* ------- ---- Beginning of user heap. Can vary with other settings.
