- * The Atmel AT91SAM9 series has a small resource of 4 nonvolatile
- * 32 Bit registers (buffered by the Vbu power).
- *
- * Please consider carefully before using this resource for tasks
- * that do not really need nonvolatile registers. Maybe you can
- * store information in EEPROM or FLASH instead.
- *
- * However, if you use a GPBR please document its use here and
- * reference the define in your code!
- *
- * known typical uses of the GPBRs:
- * GPBR[0]: offset for RTT timekeeping (u-boot, kernel)
- * GPBR[1]: unused
- * GPBR[2]: unused
- * GPBR[3]: bootcount (u-boot)
