-/* CONFIG_SYS_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.

- lookup tables: index->polynomial form alpha_to[] contains j=alpha**i;

- alpha=2 is the primitive element of GF(2**m)
- HARI's COMMENT: (4/13/94) alpha_to[] can be used as follows:
- Let @ represent the primitive element commonly called "alpha" that
- is the root of the primitive polynomial p(x). Then in GF(2^m), for any
- 0 <= i <= 2^m-2,
- @^i = a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
- where the binary vector (a(0),a(1),a(2),...,a(m-1)) is the representation
- of the integer "alpha_to[i]" with a(0) being the LSB and a(m-1) the MSB. Thus for
- example the polynomial representation of @^5 would be given by the binary
- representation of the integer "alpha_to[5]".
- Similarily, index_of[] can be used as follows:
- As above, let @ represent the primitive element of GF(2^m) that is
- the root of the primitive polynomial p(x). In order to find the power
- of @ (alpha) that has the polynomial representation
- a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
- we consider the integer "i" whose binary representation with a(0) being LSB
- and a(m-1) MSB is (a(0),a(1),...,a(m-1)) and locate the entry
- "index_of[i]". Now, @^index_of[i] is that element whose polynomial
- representation is (a(0),a(1),a(2),...,a(m-1)).
- NOTE:
- The element alpha_to[2^m-1] = 0 always signifying that the
- representation of "@^infinity" = 0 is (0,0,0,...,0).
- Similarily, the element index_of[0] = A0 always signifying
- that the power of alpha which has the polynomial representation
- (0,0,...,0) is "infinity".
