+ *   hal/hal_lpc1768/persistent_store_flash.cpp
+ *
+ * This has only be written against those that use a single "sector" design.
+ *
+ * Those that deal with "pages" could be made to work. Looking at the STM32F07 for example, there are
+ * 128 "pages", each 2kB in size. If we continued with our EEPROM being 4Kb, we'd always need to operate
+ * on 2 of these pages. Each write, we'd use 2 different pages from a pool of pages until we are done.
