Thanks to Johannes Sjölund for reporting that the Bus Pirate init could
not deal with a Bus Pirate which is already in binary Bitbang mode.

This is caused by a combination of the slowness of the Bus Pirate, the
slowness of USB and a fast serial port flush routine which just flushes
the buffer contents and does not wait until data arrival stops.

Make the Bus Pirate init more robust by running the flush command 10
times with 1.5 ms delay in between.

This code development was sponsored by Mattias Mattsson. Thanks! Tested
a few dozen times, should work reliably.

AMD SB700 and later have an integrated microcontroller (IMC) which runs
from shared flash.

The IMC will happily issue reads while we write, issue writes while we
read, and generally cause lots of havoc due to the concurrent accesses
it performs while flashrom is running. A failing or corrupted read can
be detected since r1145, and the worst case is that the read aborts and
the user has to retry. A failing write is much more serious. It can
be detected since r1145, but if the SPI interface locks up, we can't
continue writing nor can we read the current chip contents.

If the IMC is inactive, there is no reason to worry. If the IMC is
active, flashrom will refuse to erase/write the chip with this patch.

The correct fix would be to stop the IMC during flashing, but apparently
the relevant registers are undocumented, so we take the safe route for
now until someone from AMD can give us more info.

Some flash chips need time to exit ID mode, and while we take care of
correct timing for the matching probe, subsequent probes may have
totally different timing, and that can lead to garbage responses from
the flash chip during the first accesses after the probe sequence is
done.
Delay 100 ms between the last probe and any subsequent operation.
To ensure maximum correctness, we would have to reset the chip first in
case the last probe function left the chip in an undefined (non-read)
state. That will be possible once struct flashchip has a .reset
function.

This fixes unstable erase/read/write for some flahs chips on nic3com and
possible other use cases as well.

Thanks to Maciej Pijanka for reporting the issue and testing patches.

SPI bitbanging on devices which speak SPI natively has a dual-use
problem: We need to shut down normal SPI operations to do the bitbanging
ourselves. Once we're done, it makes a lot of sense to reenable "normal"
SPI operations again. Add request_bus/release_bus functions to struct
bitbang_spi_master.
Add a bitbang shutdown function (not used yet).
Change MCP SPI and Intel NIC SPI to use the new request/release bus
infrastructure.
Cosmetic changes to a few error messages (80 column limit).

There are multiple possible strategies for bus request/release:
- Request at the start of a SPI command, release immediately afterwards.
- Request at the start of a SPI multicommand, release once all commands
of the multicommand are done.
- Request on programmer init, release on shutdown.
Each strategy has its own advantages. For now, we will stay with the
first strategy which worked fine so far.

ICH SPI has the ability to restrict SPI read/write accesses to a given
address range. The low end of the range is configurable by the BIOS (and
by flashrom if the BIOS didn't lock down the flash interface), the high
end of the range is 0xffffff (2^24-1).
This patch checks for an address range restriction and uses the low end
of the allowed range as base for SPI reads. A similar workaround for
REMS/RES opcodes has been committed in r500.

This fixes read on the Intel D945GCLF mainboard where the stock BIOS
enforces a restricted address range.
Please note that writes need the same fix, but for architectural reasons
that fix will be merged once partial write is available.

Add paranoid checks for correct values in essential registers in the SB600/SB700/... SPI driver. If something else changes the values we
wrote, we will see severe read/write corruption.
sb600spi will now abort the access and return an error if it detects
this sort of corruption.

Note: This corruption can be caused by a few different events:
- IPMI/BMC/IMC accesses flash
- Other software accesses flash
The nature of flash access (read/write/ID/...) is irrelevant. Each such
access will cause corruption for all other accesses happening at the
same time.

This patch changes the intel_piix4_gpo_set() function to always check
the GENCFG and XBCS registers for the availability of the
requested GPO line before raising/lowering it and fails otherwise. It
makes no attempt to bypass the values in these configuration
registers.

The old flashrom code did consider it safe to reprogram (multiplexed)
GPO:s 22-26 without checking the value of the controlling register
(GENCFG). I do not really know why.

I have tested this patch on an Asus P2B-N (needs GPO18 low) and MSI
MS-6163 Pro (needs GPO14 high).

The information for these registers are from the Intel "82371AB
PCI-TO-ISA / IDE XCELERATOR (PIIX4)" datasheet available here:

- There are number of boards that have board-enables in board-enable.c but
  have no corresponding entry in print.c (with or without URL doesn't matter)
  and thus appear neither in the "flashrom -L" list of boards nor in the
  wiki output. Fix this by adding entries for them in print.c.

   - abit AN-M2
   - abit KN8 Ultra
   - ASUS A8Jm (laptop)
   - ASUS A8N (might need changing to "A8N-SLI Deluxe", see
     http://www.coreboot.org/pipermail/flashrom/2009-November/000878.html)
   - ASUS A8N-LA (Nagami-GL8E)
   - ASUS P4B533-E
   - ASUS P4S800-MX
   - HP ProLiant DL165 G6
   - IBASE MB899
   - Intel SE440BX-2 (marked as non-working for now though, due to
     http://www.coreboot.org/pipermail/flashrom/2010-July/003952.html

)
   - MSI MS-6577 (Xenon)
   - MSI MS-7207 (K8NGM2-L)

- Fix / amend a few board names:

   - Add "ProLiant" name to the "DL145 G3" (and the new "DL165 G6"), we
     use such "series" names for various other boards (e.g. "Vectra" etc)
     and it also helps users googling for those names.

   - HP "Vectra VL400 PC" should be "Vectra VL400" really, I'm pretty sure
     the "PC" is not part of the board name but simply stands for
     "personal computer". Same for "Vectra VL420 SFF PC".

   - Change "ASUS A8JM" to "ASUS A8Jm" as per vendor website.

   - Add comments for boards which may be listed with incorrect names,
     I sent out clarification requests to the list, URLs listed as comment.

   - Add "Xenon" HP name to the "MSI MS-6577" OEM board.

   - Fix typo in "MS-7207 (K8N GM2-L)", should be "MS-7207 (K8NGM2-L)" as
     per vendor website.

Change the DMI string to only match this exact board (DMI "NAGAMI2L")
as only this one is tested.

Similar HP OEM boards might also work using this board-enable but that's
not sure and not tested. Two of those boards have DMI strings "NAGAMI"
and "NAGAMI2".
