/* The S32K118 has 256KB of FLASH beginning at address 0x0000:0000 and
 * 23KB of SRAM beginning at address 0x1fff:fc00 (plus 2Kb of FlexRAM)
 *
 * The on-chip RAM is split in two regions: SRAM_L and SRAM_U. The RAM is
 * implemented such that the SRAM_L and SRAM_U ranges form a contiguous
 * block in the memory map
 *
 *   SRAM_L 1ffffc00 - 1fffffff 1Kb
 *   SRAM_U 20000000 - 200057ff 22Kb
