/*
* 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
* ............[DWord][DWord]
* FFFF....FFFF[DWord][DWord]
* FFFFFFFFFFFF[DWord][DWord]
* ....FFFFFFFF[DWord][DWord]
*
* PAGE_BASE
* PAGE_LASTWRITE_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 one pages of 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 8192. 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 1/2/4 byte(s) 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 ***
*
* Each log entry compose of double word (2 x 32-bit) due to the minimum program size of STM32L432 flash.
*
* === WRITE LOG ENTRY FORMATS ===
*
* Byte-Entry
* 00 01 XX XX FF FF FF YY
*
* Len Address ~Value
*
*
* Word-Entry
* 00 02 XX XX FF FF YY YY
*
* Len Address ~Value
*
*
* DWord-Entry
* 00 04 XX XX FF FF FF FF
*
* Len Address ~Value
*
