The continuation ID code does not go further than checking for IDs of
the type 0x7fXX, but does this for vendor and product ID. The current
published JEDEC spec has a list where the largest vendor ID is 7 bytes
long, but all leading bytes are 0x7f. The list will grow in the future,
and using a 64bit variable will not be enough anymore.
Besides that, it seems that the location of the ID byte after the first
continuation ID byte is very vendor specific, so we may have to revisit
that code some time in the future.

(Suggestion for a new encoding:
Use a two-byte data type for the ID, the lower byte contains the only
non-0x7f byte, the upper byte contains the number of 0x7f bytes used as
prefix, which is the bank number minus 1 the vendor ID appears in.)

Add support for EON EN29F002AT.

This fixes a few vendor IDs to conform with JEDEC publication 106W
(JEP106W), adds some device IDs and provides information about
non-conforming IDs. The EON change is left to the patch adding EON
chips.

This patch should have no effect on code generation.

To make it easier to add new SPI chips to flashchips.c, rename functions
with multiple possible opcodes from linear numbering at the end (_1, _2)
to include the opcode at the end (_60, _c7).

That way, you only have to take a short look at the data sheet and
choose the right function by appending the opcode listed in the data
sheet. No functional changes.

The JEDEC probe routine had a delay of 10 us after entering ID mode
and this was insufficient for the 29C020. The data sheet claims we
have to wait 10 ms, but tests have shown that 20 us suffice. Allow for
variations in chip delays with a factor of 2 safety margin.

hardcoded to data sheet maxima, but the status register checking code is
already there. Thanks to Harald Gutmann for the initial code on which
this is loosely based.

The SPI chip finding and SPI chip accessor code is moved as well. This
can be split later if we feel like it.

The non-use of svn cp is intentional because the only history we'd
have to preserve are a few commits which were early prototypes of chip
identification code. For those who intend to look at that history, they
can look at board_enable.c revision 2853.

It introduces a generic SPI host driver for the IT8716F Super I/O
which will enable easy SPI programming without having to care for the
peculiarities of the SPI host.

To activate probing for the IT8716F, you have to use the gigabyte:m57sli
mainboard override. SPI support will then use the gathered SPI host data
to access the SPI flash.

This has been tested sucessfully by Ward Vandewege <ward@gnu.org> on the
GA-M57SLI v2.0, which has a MX25L4005 SPI flash part.

I'm self-ack'ing this, as the origin of the code in udelay.c (and thus
the license and copyright owner) is pretty clear.

The code which is now in udelay.c was split out from flash_rom.c in r1428,
and flash_rom.c, in turn, has been around since the beginning and had a
'Copyright 2000 Silicon Integrated System Corporation' line as well as the
usual GPLv2-or-later license header.
