Cosmetic changes in some files, partly bending the 80-characters-per-line
rule in this special case, as the 80-character-limited version looks
equally crappy even in an 80x25 console/xterm, so let's make it at least
look good in a high-resolution xterm.

Some vendors like Programmable Micro Corp (PMC) need this. Both the
serial and parallel flash JEDEC detection routines would benefit from a
parity/sanity check of the vendor ID. Will do this later.

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 first chip the code was tested and verified with is the Macronix
MX25L4005, but other chips should work as well. Timeouts are still
hardcoded to data sheet maxima, but the status register checking code is

this is loosely based.

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.
