- * Set of macros for encoding and decoding header for log entries.
- * There are 2 types of entries:
- * 1. Standard entry (STD)
- * An entry consists of header, pointer to string and values. Header contains
- * severity leveland determines number of arguments and thus size of the entry.
- * Since flash address space starts from 0x00000000 and is limited to kB rather
- * than MB 22 bits are used to store the address (4MB). It is used that way to
- * save one RAM memory.
- *
- * --------------------------------
- * |TYPE|SEVERITY|NARGS| P_STR |
- * |------------------------------|
- * | Module_ID (optional) |
- * |------------------------------|
- * | TIMESTAMP (optional) |
- * |------------------------------|
- * | ARG0 |
- * |------------------------------|
- * | .... |
- * |------------------------------|
- * | ARG(nargs-1) |
- * --------------------------------
- *
- * 2. Hexdump entry (HEXDUMP) is used for dumping raw data. An entry consists of
- * header, optional timestamp, pointer to string and data. A header contains
- * length (10bit) and offset which is updated after backend processes part of
- * data.
