With this, you can run "grep -i ft2232_spi" and find everything related

Unistd.h was only used to get a definition of NULL in all files. Add our
own NULL #define and remove unistd.h from flash.h
stdio.h has no place in flash.h, it should be included only in files
which really need it.
Add #include statements in individual .c files where needed.
Replace a few printf with msg_* to eliminate the need for stdio.h.

ICH SPI can enforce address restrictions for all accesses which take an
address (well, it could if the chipset implementation was not broken).
Since exploiting the broken implementation is harder than conforming
to the address restrictions wherever possible, conform to the address
restrictions instead. This patch eliminates a lot of transaction errors
people were seeing on chip probe.

- 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.

SPI RES is the most unreliable way to identify chips because it only
returns a 1-byte ID for most chips.
For every given ID out there, probably a dozen incompatible flash
chips match it. We already refuse to identify a chip with RES if that
chip responds to RDID (3 bytes, good match), and with this patch we
additionally refuse RES if the chip responds to REMS (2 bytes, still a
good match). This increases matching accuracy a lot.
Besides that, the RDID/REMS response checking has been cleaned up for
better readability.

Reverse engineered from USB logs. I never touched that programmer nor
did I ever see the associated software.
Disabled by default until it is complete. The driver needs to be hooked
up to the SPI core before it will do anything besides init and
diagnostics.
I successfully reverse engineered all commands, but some are still
somewhat magic.
Logs from "flashrom -p dediprog -V" are appreciated.
Probe and read should work, erase/write is expected to explode.
The programmer will set voltage to 0 on exit.
Thanks a lot to Stefan Reinauer and Patrick Georgi for providing USB
logs and for testing the result.

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.

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

#define FAKE_COMMUNICATION in buspirate_spi.c.

If a chip is not on the RDID generic vendor list nor on the REMS
specific ID list, flashrom will claim that no chip is there.
Handle these cases gracefully. flashrom will ignore generic matches if a
specific chip was found, so this will have no impact on supported chips,
but help a lot for a first quick analysis by the user or developer. The
only drawback is that unknown chips may be recognized multiple times
until they are added to flashchips.[ch].

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.

Example make commandline if you want only internal programmers:
make CONFIG_FT2232SPI=no CONFIG_SERPROG=no CONFIG_NIC3COM=no
CONFIG_SATASII=no CONFIG_DRKAISER=no CONFIG_DUMMY=no
Of course, all of the CONFIG_* symbols can be mixed and matched as
needed. CONFIG_FT2232SPI is special because even if it is enabled, make
will check if the headers are available and skip it otherwise.

I decided to fill in the info for a
few chips to illustrate how this works both for uniform and non-uniform
sector sizes.
struct eraseblock{
int size; /* Eraseblock size */
int count; /* Number of contiguous blocks with that size */
};
struct eraseblock doesn't correspond with a single erase block, but with
a group of contiguous erase blocks having the same size.
Given a (top boot block) flash chip with the following weird, but
real-life structure:
top
16384
8192
8192
32768
65536
65536
65536
65536
65536
65536
65536
bottom
we get the following encoding:
{65536,7},{32768,1},{8192,2},{16384,1}
Although the number of blocks is bigger than 4, the number of block
groups is only 4. If you ever add some flash chips with more than 4
contiguous block groups, the definition will not fit into the 4-member
array anymore and gcc will recognize that and error out. No undetected
overflow possible. In that case, you simply increase array size a bit.
For modern flash chips with uniform erase block size, you only need one
array member anyway.
Of course data types will need to be changed if you ever get flash chips
with more than 2^30 erase blocks, but even with the lowest known erase
granularity of 256 bytes, these flash chips will have to have a size of
a quarter Terabyte. I'm pretty confident we won't see such big EEPROMs
in the near future (or at least not attached in a way that makes
flashrom usable). For SPI chips, we even have a guaranteed safety factor
of 4096 over the maximum SPI chip size (which is 2^24). And if such a
big flash chip has uniform erase block size, you could even split it
among the 4 array members. If you change int count to unsigned int
count, the storable size doubles. So with a split and a slight change of
data type, the maximum ROM chip size is 2 Terabytes.
Since many chips have multiple block erase functions where the
eraseblock layout depends on the block erase function, this patch
couples the block erase functions with their eraseblock layouts.
struct block_eraser {
struct eraseblock{
unsigned int size; /* Eraseblock size */
unsigned int count; /* Number of contiguous blocks with that size */
} eraseblocks[NUM_ERASEREGIONS];
int (*block_erase) (struct flashchip *flash, unsigned int blockaddr, unsigned int blocklen);
} block_erasers[NUM_ERASEFUNCTIONS];

The __func__ variant is standardized in C99 and recommended to be
used instead of __FUNCTION__ in the gcc info page.
Only _very_ old versions of gcc did not know about __func__, but we've
been using both __func__ and __FUNCTION__ for a long while now, and
nobody complained about this, so all our users seem to use recent
enough compilers.

If we only send an opcode and no additional data/address, the SPI
controller will read one byte too few from the chip. Basically, the
last byte of the chip response is discarded and will not end up in the
FIFO. It is unclear if the CS# line is set high too early as well. That
hardware bug is undocumented as of now, but I'm working with AMD to add
a detailed description of it to the errata.
Add loads of additional debugging to SB600/SB700 init.
Add explanatory comments for unintuitive code flow.
Thanks go to Uwe for testing quite a few iterations of the patch.
Kill the SB600 flash chip status register special case, which was a
somewhat misguided workaround for that hardware erratum.
Note for future added features in the SB600 SPI driver: It may be
possible to read up to 15 bytes of command response with overlapping
reads due to the ring buffer design of the FIFO if the command can be
repeated without ill effects. Same for skipping up to 7 bytes between
command and response.

Some SPI opcodes need to be sent in direct succession after each other
without any chip deselect happening in between. A prominent example is
WREN (Write Enable) directly before PP (Page Program). Intel calls the
first opcode in such a row "preopcode".
Right now, we ignore the direct succession requirement completely and it
works pretty well because most onboard SPI masters have a timing or
heuristics which make the problem disappear.
The FT2232 SPI flasher is different. Since it is an external flasher,
timing is very different to what we can expect from onboard flashers and
this leads to failure at slow speeds.
This patch allows any function to submit multiple SPI commands in a
stream to any flasher. Support in the individual flashers isn't
implemented yet, so there is one generic function which passes the each
command in the stream one-by-one to the command functions of the
selected SPI flash driver.

Since block erase functions do not know the block length (it's not
specified in any standard), block erase functions now get an additional
parameter blocklen. This enables flashrom to verify the erase result for
block erase functions at correct boundaries.

chip from FTDI
FTDI support is autodetected during compilation.
Paul writes:
There are certainly possible improvements: The code has hard-coded
values for which interface of the ftdi chip to use (interface B was
chosen because libftdi seems to have trouble with A right now), what
clock rate use for the SPI interface (I've been running at 30Mhz, but
the patch sets it to 10Mhz), and possibly others. I think this means
that per-programmer options might be a good idea at some point.
Carl-Daniel writes:
There is one additional FIXME comment in the code, but AFAICS that
problem is not solvable with current libftdi.

That means you can tell flashrom to read exactly bytes 12345-56789
(start 12345, length 44445) and it will not fetch a single byte more.
Uwe tested this on one LPC, one SPI, and one parallel flash board.

Flash.h not only contains function prototypes and general settings, it
also has a huge chunk of chip and vendor IDs in the middle.
Split them out into a separate flashchips.h and adjust #include wherever
needed.

This was partly due to a design problem in the abstraction layer.
There should be exactly two different functions for reading SPI chips:
- memory mapped reads
- SPI command reads.
Each of them should be contained in a separate function, optionally
taking parameters where needed.
This patch solves the problems mentioned above, shortens the code and
makes the code logic a lot more obvious.
Since open-coding the min() function leads to errors, include it in this
patch as well.

Right now, the annotation only differentiates between SPI and non-SPI.
Anyone who knows more about a specific flash chip should feel free to
update it.
The existing flashbus variable was abused to denote the SPI controller
type. Use an aptly named variable for that purpose.
Once this patch is merged, the chipset/programmer init functions can set
supported flash chip types and flashrom can automatically select only
matching probe/read/erase/write functions. A side benefit of that will
be the elimination of the Winbond W29EE011 vs. AMIC A49LF040A conflict.

Every chip besides SPI and w39v080fa uses id1/id2 as local variable
names to store ID responses from the flash chip. This eases grepping a
lot. As a bonus, it also frees up some names to be used as parameters.

Until the ICH SPI driver can handle preopcodes as standalone opcodes,
we should handle such special opcode failure gracefully on ICH and
compatible chipsets.
This fixes status register writes on almost all ICH+VIA SPI masters.
The fix is almost identical to r484, but this time it affects the EWSR
(Enable Write Status Register) opcode instead of the WREN (Write Enable)
opcode.
With the differentiated return codes introduced in r500, the workaround
is more precise this time. The old WREN workaround was updated as well.

flasher driver
Does not support reading or writing the fake chip yet.
flashrom --programmer dummy

Among others, I have seen the following problems: - The SPI opcode is
not supported by the controller. ICH-style controllers exhibit this if
SPI config is locked down. - The address in in a prohibited area. This
can happen on ICH for any access (BBAR) and for writes in chipset write
protected areas. - There is no SPI controller.
Introduce separate error codes for unsupported opcode and prohibited
address.
Add the ability to adjust REMS and RES addresses to the minium supported
read address with the help of spi_get_valid_read_addr(). That function
needs to call SPI controller specific functions like reading BBAR on
ICH.
