-/*
- * We emulate eeprom by writing a snapshot compacted view of eeprom contents,
- * followed by a write log of any change since that snapshot:
- *
- * === SIMULATED EEPROM CONTENTS ===
- *
- * ┌─ Compacted ┬ Write Log ─┐
- * │............│[BYTE][BYTE]│
- * │FFFF....FFFF│[WRD0][WRD1]│
- * │FFFFFFFFFFFF│[WORD][NEXT]│
- * │....FFFFFFFF│[BYTE][WRD0]│
- * ├────────────┼────────────┤
- * └──PAGE_BASE │            │
- *    PAGE_LAST─┴─WRITE_BASE │
- *                WRITE_LAST ┘
- *
- * Compacted contents are the 1's complement of the actual EEPROM contents.
- * e.g. An 'FFFF' represents a '0000' value.
- *
- * The size of the 'compacted' area is equal to the size of the 'emulated' eeprom.
- * The size of the compacted-area and write log are configurable, and the combined
- * size of Compacted + WriteLog is a multiple FEE_PAGE_SIZE, which is MCU dependent.
- * Simulated Eeprom contents are located at the end of available flash space.
- *
- * The following configuration defines can be set:
- *
- * FEE_PAGE_COUNT   # Total number of pages to use for eeprom simulation (Compact + Write log)
- * FEE_DENSITY_BYTES   # Size of simulated eeprom. (Defaults to half the space allocated by FEE_PAGE_COUNT)
- * NOTE: The current implementation does not include page swapping,
- * and FEE_DENSITY_BYTES will consume that amount of RAM as a cached view of actual EEPROM contents.
- *
- * The maximum size of FEE_DENSITY_BYTES is currently 16384. The write log size equals
- * FEE_PAGE_COUNT * FEE_PAGE_SIZE - FEE_DENSITY_BYTES.
- * The larger the write log, the less frequently the compacted area needs to be rewritten.
- *
- *
- * *** General Algorithm ***
- *
- * During initialization:
- * The contents of the Compacted-flash area are loaded and the 1's complement value
- * is cached into memory (e.g. 0xFFFF in Flash represents 0x0000 in cache).
- * Write log entries are processed until a 0xFFFF is reached.
- * Each log entry updates a byte or word in the cache.
- *
- * During reads:
- * EEPROM contents are given back directly from the cache in memory.
- *
- * During writes:
- * The contents of the cache is updated first.
- * If the Compacted-flash area corresponding to the write address is unprogrammed, the 1's complement of the value is written directly into Compacted-flash
- * Otherwise:
- * If the write log is full, erase both the Compacted-flash area and the Write log, then write cached contents to the Compacted-flash area.
- * Otherwise a Write log entry is constructed and appended to the next free position in the Write log.
- *
- *
- * *** Write Log Structure ***
- *
- * Write log entries allow for optimized byte writes to addresses below 128. Writing 0 or 1 words are also optimized when word-aligned.
- *
- * === WRITE LOG ENTRY FORMATS ===
- *
- * ╔═══ Byte-Entry ══╗
- * ║0XXXXXXX║YYYYYYYY║
- * ║ └──┬──┘║└──┬───┘║
- * ║ Address║ Value  ║
- * ╚════════╩════════╝
- * 0 <= Address < 0x80 (128)
- *
- * ╔ Word-Encoded 0 ╗
