+/*
+ * 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.
+ * NB. These undocumented bits does not work for all MCUs.
+ * A more reliable way is to detect the particular MCU model from the
+ * SDID field and pick the correct granularity based on that. See
+ * the handling of K21 in kinetis_read_part_info() for an example.
