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.

Move SPI code out of board_enable.c where it started its life. 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.

way. 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

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.

The first byte of the flash chip was read at the start of the function
and later written back to address 0 if the flash chip was not identified
as SST28SF040, which means most of the time. This write caused corruption
