Attached is a patch that enables AMD Geode CS5536 chipset support. I
have tested it successfully on a MSM800 board from digital logic.

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.

Looking through the sources of Uniflash utility I found that this chip
is no more no less than low-voltage variant of Am29F040B but with
different ID.
So I created a very quick patch (attached).

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 already there.
Thanks to Harald Gutmann for the initial code on which this is loosely
based.

- Install binary in /usr/sbin (not /usr/bin), as it's a root-only tool.
- Rename manpage from flashrom.1 to flashrom.8, as section 8 contains
"System administration commands (usually only for root)".
- Actually install the manpage upon 'make install'.

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
GA-M57SLI v2.0, which has a MX25L4005 SPI flash part.

to ITE IT8716F Super I/O. Right now this is hardcoded to the Gigabyte
M57SLI board. It works only with rev 2.0 of the board, but it will bail
out on earlier versions, so no damage can occur.

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
of flash contents when verifying a SST49LF160C part.

The previous code was pretty unreadable, undocumented and did some totally
unrelated things (such as mucking with the game port or port 0x92).
This version is tested with a 256 KB chip and should work for the
CS5530 and CS5530A.
