/* The STM32L476VG has 1024Kb of FLASH beginning at address 0x0800:0000,
* 96Kb of SRAM beginning at address 0x2000:0000, and 32Kb of SRAM2 beginning
* at address 0x1000:0000. The SRAM2 has special properties (e.g. parity
* check, separate power domain for retention in low power modes, write
* protection). Alas, it is non-contiguous with main SRAM.
* 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.
