cceafa2ad0 Handle the following architectures in generic flashrom code
- x86/x86_64 (little endian)
- PowerPC (big endian)
- MIPS (big+little endian)

No changes to programmer specific code. This means any drivers with MMIO
access will _not_ suddenly start working on big endian systems, but with
this patch everything is in place to fix them.

Compilation should work on all architectures listed above for all
drivers except nic3com and nicrealtek which require PCI Port IO which is
x86-only for now.

To compile without nic3com and nicrealtek, run
make distclean
make CONFIG_NIC3COM=no CONFIG_NICREALTEK=no

Thanks to Misha Manulis for testing early versions of this patch on
PowerPC (big endian) with the satasii programmer.
Thanks to Segher Boessenkool for design review and for helping out with
compiler tricks and pointing out that we need eieio on PowerPC.
Thanks to Vladimir Serbinenko for compile testing on MIPS (little
endian) and PowerPC (big endian) and for runtime testing on MIPS (little
endian).
Thanks to David Daney for compile testing on MIPS (big endian).
Thanks to Uwe Hermann for compile and runtime testing on x86_64.

DO NOT RUN flashrom ON NON-X86 AFTER APPLYING THIS PATCH!
This patch only provides the infrastructure, but does not convert any
drivers, so flashrom will compile, but it won't do the right thing on
non-x86 platforms.

270237687a One of the problems is that --force had multiple meanings
- Force chip read by faking probe success.
- Force chip access even if the chip is bigger than max decode size for
  the flash bus.
- Force erase even if erase is known bad.
- Force write even if write is known bad.
- Force writing even if cbtable tells us that this is the wrong image
  for this board.

This patch cleans up --force usage:
- Remove any suggestions to use --force for probe/read from flashrom
  output.
- Don't talk about "success" or "Found chip" if the chip is forced.
- Add a new internal programmer parameter boardmismatch=force. This
  overrides any mismatch detection from cbtable/image comparisons.
- Add a new internal programmer parameter laptop=force_I_want_a_brick.
- Adjust the documentation for --force.
- Clean up the man page a bit whereever it talks about --force or
  laptops.

Additional changes in this patch:
- Add warnings about laptops to the documentation.
- Abort if a laptop is detected. Can be overridden with the programmer
parameter mentioned above.
- Add "Portable" to the list of DMI strings indicating laptops.
- Check if a chip specified with -c is known to flashrom.
- Programmer parameter reliability and consistency fixes.
- More paranoid self-checks.
- Improve documentation.

e8e369fcc3 Write granularity is chip specific
The following write granularities exist according to my datasheet
survey: - 1 bit. Each bit can be cleared individually. - 1 byte. A byte
can be written once. Further writes to an already written byte cause
the contents to be either undefined or to stay unchanged. - 128 bytes.
If less than 128 bytes are written, the rest will be erased. Each write
to a 128-byte region will trigger an automatic erase before anything is
written. Very uncommon behaviour. - 256 bytes. If less than 256 bytes
are written, the contents of the unwritten bytes are undefined.

Note that chips with default 256-byte writes, which keep the original
contents for unwritten bytes, have a granularity of 1 byte.

Handle 1-bit, 1-byte and 256-byte write granularity.

cc389fc6b1 Allow the registration of functions to be called at programmer shutdown
Some programmers want to run certain functions during programmer
shutdown, but the function choice depends on the code path taken
during programmer init. Rather than rebuilding the whole init logic in
the shutdown function, it is now possible to register functions for
execution on programmer shutdown. The behaviour is similar to atexit(),
but the registered functions will be run on programmer shutdown instead
of on exit and the functions will be called with a void * argument
that is specified on registration. Registered functions must have
the prototype void function(void *); and will be executed in reverse
registration order directly before calling the programmer-specific
shutdown() function. It is recommended to have shutdown() only disable
programmer/hardware access and leave all code path sensitive shutdown to
functions registered with register_shutdown().

The most prominent use case is resetting the EC after flashing on
laptops.

Note: There are quite a few code paths in flashrom which proceed to
terminate flashrom without any programmer shutdown. Those code paths
will not get the benefit of register_shutdown() and they should be
changed wherever possible.

baaffe0831 Create a physical memory mapping function which requests cached readonly memory
This should take care of picky Linux kernels which do not allow uncached
mappings to cached areas. Handle mapping failure gracefully (no forced
exit()) if the caller specifies it.

Such cached areas which can handle mapping failure are DMI tables and
coreboot tables. On failure we just ignore those tables. That is not
perfect, but a lot better than aborting flashrom due to an error in
nonessential functionality.

This should fix flashrom on a sizable number of machines where it
currently aborts early.

Yes, I could have exploited a Linux kernel bug to "solve" this, but
relying on such bugs is not exactly the best idea.

6701ee833c Matching board via DMI
If a board is not uniquely identifiable by PCI device/subsystem IDs, a
string can be specified to be looked for (case-sensitive, substring or
anchored) for now in one of the following DMI items in addition to matching
the PCI IDs:
 - System Manufacturer
 - System Product Name
 - System Version
 - Baseboard Manufacturer
 - Baseboard Product Name
 - Baseboard Version

Strings are anchored re-like (^ at the beginning, $ at the end), but
there are no plans to support full regular expressions and matched to any
of the mentioned fields.

The match is only made if DMI info is available and the string matches.
If no DMI info is available and the PCI IDs match, a warning is printed
as the board can not be autodetected.

It's still open to discussion whether we add an DMI override switch to
specify a string that will definitely match, and whether this switch is
only used if no DMI is available or whether it overrides or augments DMI
data.

DMI data is currently read using dmidecode. This tool is available for
all major platforms except MacOS X. I heard that there also is a MacOS X
version of dmidecode, but didn't investigate that.

66ef4e5ff3 Internal (onboard) programming was the only feature which could not be disabled
Make various pieces of code conditional on support for internal
programming. Code shared between PCI device programmers and onboard
programming is now conditional as well.

It is now possible to build only with dummy support:
make CONFIG_INTERNAL=no CONFIG_NIC3COM=no CONFIG_SATASII=no
CONFIG_DRKAISER=no CONFIG_SERPROG=no CONFIG_FT2232SPI=no

This allows building for a specific use case only, and it also
facilitates porting to a new architecture because it is possible to
focus on highlevel code only.

Note: Either internal or dummy programmer needs to be compiled in due to
the current behaviour of always picking a default programmer if -p is
not specified. Picking an arbitrary external programmer as default  
wouldn't make sense.

Build and runtime tested in all 1024 possible build combinations. The
only failures are by design as mentioned above.

1c296ca8bc Use common jedec functionality where appropriate
The deleted function in en29f002a.c is reintroduced as
write_by_byte_jedec in jedec.c as it contains no chip-specific
instructions. It is not yet used in other chip drivers, as key addresses
(0x2AAA/0x5555) are often specified with less bits. After crosschecking
datasheets, most of the fixmes can probably be resolved as indicated in
them, causing significant code reduction.

The common JEDEC code for bytewise programming does not program 0xFF
at all. The chips that had a dedicated bytewise flash function which
has been changed to write_jedec_1 thus changed flashing behaviour
and the "write" test flag has been removed. This applies to: AMD
Am29F002BB/Am29F002NBB AMD Am29F002BT/Am29F002NBT (TEST_OK_PREW before)
AMIC A29002B AMIC A29002T (TEST_OK_PREW before) EON EN29F002(A)(N)B EON
EN29F002(A)(N)T (TEST_OK_PREW before) Macronix MX29F001B (TEST_OK_PREW
before) Macronix MX29F001T (TEST_OK_PREW before) Macronix MX29F002B
Macronix MX29F002T (TEST_OK_PREW before) Macronix MX29LV040

Similar analysis should be performed for the read id stuff.

972cec282c Refine support for the JEDEC Software Data Protection
This patch removes the extremely dangerous unprotect_jedec function
which is not used at all within flashrom code, and renames the
misleadingly named protect_jedec function to start_program_jedec.

Calls to protect_jedec after flashing are removed, because a) on LPC
chips, the command sent by protoct_jedec is not even in the datasheet
and b) on parallel chips, the block write command issued before already
contained the software protection sequence, so software protection is
definitely enabled.

This patch also removes two clones of protect_jedec

Background: JEDEC Software Data Protection started as an optional
feature, which was disabled on the first single-voltage-flash chips.
The software data protection is the need to prefix a write with a magic
"write enable" command, while without write protection every write
access into the chip's address space modifies flash content. This magic
write enable command also tells the flash chip that the programmer
obviously support sending write-enable commands and turns off the "any
write modifies flash content" mode. There also exist a two-command (6
writes) sequence that disables Software Data Protection completey, which
should only ever be used to prepare updating with a device that can't
handle software data protection.

d5b28fae1d Add the ability to set Bus Pirate SPI speed via the command line
Example usage:
flashrom -p buspiratespi:spispeed=2.6MHz,dev=/dev/foo
flashrom -p buspiratespi:dev=/dev/foo,spispeed=2.6M

Refactor programmer option parsing (this allows cleanups in other
programmers as well).

Increase SPI read size from 8 to 12 bytes (current single-transaction
limit of the Bus Pirate raw SPI protocol).

Add Bus Pirate to the list of programmers supporting 4 byte RDID.

Add Bus Pirate syntax to the man page.

5cca01f394 Cleanly validate ICH SPI preopcodes
The code should work on Linux/*BSD/MacOSX and relies on the serial code
implementation in serial.c. Support for additional platforms (Windows)
will have to be added to serial.c for this to work. For tests without a
Bus Pirate (or with non-functional serial code) it is possible to
#define FAKE_COMMUNICATION in buspirate_spi.c.
Thanks to Sean Nelson for the SPI mode settings code. I tweaked it a bit
to make configuration from a commandline easier should anybody want that
feature.

f52920581d Refactor main loop in preparation of libflashrom
To prepare for libflashrom I wanted to make the main loop more readable and more correct and factor out stuff which can be useful in libflashrom.

- Factor out printing of supported devices to print.c.
- Adjust name of wiki printing function to fit the pattern.
- Abort if the user specified --verify and --noverify at the same time.
- Check for extra parameters which don't fit commandline syntax.

9f46cfca38 Add support for every single SiS chipset out there
The two existing SiS chipset enables (compared to the 28 in this patch)
were refactored, and one of them was fixed.

A function to match PCI vendor/class combinations was added to generic
code.

Tested on the "Elitegroup K7S5A". Results are somewhat unexpected (some
PCI settings seem to be inaccessible, but it still works).

This is not based on any docs, but rather on detailed analysis
of existing opensource code for some of the chipsets.

Thanks to for Adrian Glaubitz testing.

115d390f1f Add infrastructure to check the maximum supported flash size of chipsets and mainboards
The rationale is to warn users when they, for example, try to flash
a 512KB parallel flash chip but their chipset only supports 256KB,
or they try to flash 512KB and the chipset _does_ theoretically
support 512KB but their special board doesn't wire all address lines
and thus supports only 256 KB ROM chips at maximum.

This has cost Uwe hours of debugging on some board already, until he
figured out what was going on. We should try warn our users where
possible about this.

The chipset and the chip may have more than one bus in common (e.g.
SB600 and Pm49* can both speak LPC+FWH) and on SB600/SB7x0/SB8x0 there
are different limits for LPC and FWH. The only way to tell the user
about the exact circumstances is to spew error messages per bus.

The code will issue a warning during probe (which does fail for some
chips if the size is too big) and abort before the first real
read/write/erase action. If no action is specified, the warning is
printed anyway.
That way, a user can find out why probe might not have worked, and will
be stopped before he/she gets incorrect results.

Add a bitcount function to the infrastructure.

2bc98f6c91 Add initial support for flashing some NVIDIA graphics cards
The new option is '-p gfxnvidia', rest of the interface is as usual.

I tested a successful identify and read on a "RIVA TNT2 Model 64/Model 64 Pro"
card for now, erase and write did NOT work properly so far!

Please do not attempt to write/erase cards yet, unless you can recover!

In addition to the NVIDIA handling code it was required to call
programmer_shutdown() in a lot more places, otherwise the graphics card
will be disabled in the init function, but never enabled again as the
shutdown function is not called.
The shutdown handling may be changed to use atexit() later.

26f7e64cb1 The current ICH SPI preop handling is a hack which spews lots of warnings, but still yields correct results
With the multicommand infrastructure I introduced in r645, it became
possible to integrate ICH SPI preopcodes cleanly into the flashrom
design.

The new code checks for every opcode in a multicommand array if it is a
preopcode. If yes, it checks if the next opcode is associated with that
preopcode and in that case it simply runs the opcode because the correct
preopcode will be run automatically before the opcode.
