/* The MK64FN1M0VMD12 has 1MB of FLASH beginning at address 0x0000:0000 and
* 256KB of SRAM beginning at address 0x1fff:0000 (SRAM_L 64KB) and 0x2000:0000
* (SRAM_U 192KB).
*
* NOTE: that the first part of the K64 FLASH region is reserved for
* interrupt vectflash and, following that, is a region from 0x0000:0400
* to 0x0000:040f that is reserved for the FLASH control fields (FCF).
*
* NOTE: The on-chip RAM is split evenly among SRAM_L and SRAM_U. The RAM is
* also implemented such that the SRAM_L and SRAM_U ranges form a
* contiguous block in the memory map.
