- * The PDC provides access to Non-Volatile Memory (NVM). If this
- * is implemented (it's HVERSION dependent), the first 256 bytes
- * are formatted as follows:
- *
- * 0x000 +----------------------------+
- * | Implementation information |
- * 0x024 +----------------------------+
- * | |
- * | IPL information |
- * | |
- * 0x080 +----------------------------+
- * | |
- * | |
- * | OS Panic information |
- * | |
- * | |
- * 0x100 +----------------------------+
- *
- * It appears that there are at least 256 bytes of NVM, and only
- * the "OS Panic information" is not architected. This means that
- * we can use locations 0x80 - 0xFF for saving information across
- * boots (e.g. boot flags and boot device). I think we should use
- * the higher portions of this space first, to avoid conflicting
- * with possible future HP-PA plans for the NVM.
- *
- * The PDC requires that NVM be read/written to in word multiples.
