- /*
- * 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 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 the chip granularity as
- * described below.
- *
- * Kinetis offers four different of flash granularities applicable
- * across the chip families. The granularity is apparently reflected
- * by at least the reference manual suffix. For example, for chip
- * MK60FN1M0VLQ12, reference manual K60P144M150SF3RM ends in "SF3RM",
- * where the "3" indicates there are four flash blocks with 4kiB
- * sectors. All possible granularities are indicated below.
- *
- * The first half of the flash (1 or 2 blocks, depending on the
- * granularity) 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
- * half of flash is Program Flash and is contiguous in the memory map
- * 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 granularity.
- * Some Kinetis chips have different granularity between Program Flash
- * and FlexNVM/FlexRAM, so flash command arguments may differ between
- * blocks in the same chip.
- *
- * Although not documented as such by Freescale, it appears that bits
- * 8:7 of the read-only SIM_SDID register reflect the granularity
- * settings 0..3, so sector sizes and block counts are applicable
- * according to the following table.
