Works in the usual USB DFU mode, and can program external SPI flash. It will enable XSPI memory-mapped mode before jumping to the application firmware in the external SPI flash. Signed-off-by: Damien George <damien@micropython.org>

Linker script fragment for mboot on an STM32N6xx MCU.

This defines the memory sections for the bootloader to use.
|
|
|
|
On N6, the hardware bootloader loads the first 512k of external flash into
|
|
the upper part of SRAM2 AXI S, starting at 0x34180000. The first 1024 bytes
|
|
is a header. Then comes the actual code, starting with the vector table.
