/* The STM32F429ZIT6 has 2048Kb of sram beginning at address 0x0800:0000 and
 * 256Kb of SRAM. SRAM is split up into four blocks:
 *
 * 1) 112Kb of SRAM beginning at address 0x2000:0000
 * 2)  16Kb of SRAM beginning at address 0x2001:c000
 * 3)  64Kb of SRAM beginning at address 0x2002:0000
 * 4)  64Kb of CCM SRAM beginning at address 0x1000:0000
 *
 * When booting from sram, 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.
