- /*
- * Implementation Notes
- *
- * The persistent memories in the Kinetis chip families K10 through
- * K70 are all manipulated with the Flash Memory Module. Some
- * variants call this module the FTFE, others call it the FTFL. To
- * indicate that both are considered here, we use FTFX.
- *
- * Within the module, according to the chip variant, the persistent
- * memory is divided into what Freescale terms Program Flash, FlexNVM,
- * and FlexRAM. All chip variants have Program Flash. Some chip
- * variants also have FlexNVM and FlexRAM, which always appear
- * together.
- *
- * A given Kinetis chip may have 1, 2 or 4 blocks of flash. Here we map
- * each block to a separate bank. Each block size varies by chip and
- * may be determined by the read-only SIM_FCFG1 register. The sector
- * size within each bank/block varies by chip, and may be 1, 2 or 4k.
- * The sector size may be different for flash and FlexNVM.
- *
- * The first half of the flash (1 or 2 blocks) is always Program Flash
- * and always starts at address 0x00000000. The "PFLSH" flag, bit 23
- * of the read-only SIM_FCFG2 register, determines whether the second
- * half of the flash is also Program Flash or FlexNVM+FlexRAM. When
- * PFLSH is set, the second from the first half. When PFLSH is clear,
- * the second half of flash is FlexNVM and always starts at address
- * 0x10000000. FlexRAM, which is also present when PFLSH is clear,
- * always starts at address 0x14000000.
- *
- * The Flash Memory Module provides a register set where flash
- * commands are loaded to perform flash operations like erase and
- * program. Different commands are available depending on whether
- * Program Flash or FlexNVM/FlexRAM is being manipulated. Although
- * the commands used are quite consistent between flash blocks, the
- * parameters they accept differ according to the flash sector size.
