+/* CFG_DOC_PASSIVE_PROBE:
+   In order to ensure that the BIOS checksum is correct at boot time, and
+   hence that the onboard BIOS extension gets executed, the DiskOnChip
+   goes into reset mode when it is read sequentially: all registers
+   return 0xff until the chip is woken up again by writing to the
+   DOCControl register.
+
+   Unfortunately, this means that the probe for the DiskOnChip is unsafe,
+   because one of the first things it does is write to where it thinks
+   the DOCControl register should be - which may well be shared memory
+   for another device. I've had machines which lock up when this is
+   attempted. Hence the possibility to do a passive probe, which will fail
+   to detect a chip in reset mode, but is at least guaranteed not to lock
+   the machine.
+
+   If you have this problem, uncomment the following line:

+ * 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 CFG_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.
