- * It might not be possible in all cases to use 'memcpy()' to copy
- * the environment to NVRAM, as the NVRAM might not be mapped into
- * the memory space. (I.e. this is the case for the BAB750). In those
- * cases it might be possible to access the NVRAM using a different
- * method. For example, the RTC on the BAB750 is accessible in IO
- * space using its address and data registers. To enable usage of
- * NVRAM in those cases I invented the functions 'nvram_read()' and
- * 'nvram_write()', which will be activated upon the configuration
- * #define CONFIG_SYS_NVRAM_ACCESS_ROUTINE. Note, that those functions are
- * strongly dependent on the used HW, and must be redefined for each
- * board that wants to use them.
