/* The MK28FN2M0VMI15 has 2Mb of FLASH beginning at address 0x0000:0000 and
* 1024Kb of SRAM as follows.
* This device contains TCRAM that is tightly coupled to the ARM Cortex-M4
* core as well as OCRAM that is not tightly coupled to ARM Cortex-M4 core.
* The TCRAM is split into SRAM_L and SRAM_U regions where the SRAM_L and
* SRAM_U ranges form a contiguous block in the memory map anchored at
* address 0x20000000. As such:
*
* - SRAM_L is anchored at address 0x20000000 and occupies the space below
* this address, that is, addresses less than 0x20000000.
* - SRAM_U is anchored at address 0x2000_0000 and occupies the space at and
* above this beginning address, that is, addresses greater than or equal
* to 0x20000000.
*
* FLASH is arranged as 4 blocks of 512 kB of program flash each block
* consisting of 4Kb sectors. The first part of the K28F FLASH region is
* reserved for interrupt vectflash.
