* Implementation Notes
* 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
+ * 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 the chip granularity as
- * described below.
+ * 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.
*
- * 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 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 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.
+ * parameters they accept differ according to the flash sector size.
*
- * 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.
