a73fb4983d Refine -L output to include all programmer modules
Flashrom -L output did not contain a list of programmers nor were
all programmers listed. Fix it and mention at least the name of each
programmer. Wiki output is unchanged, and will need separate fixups.

9ad4255b5e Delay between probe and subsequent operations
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.

5b997c3ed6 Split off programmer.h from flash.h
Programmer specific functions are of absolutely no interest to any file
except those dealing with programmer specific actions (special SPI
commands and the generic core).

The new header structure is as follows (and yes, improvements are
possible):
flashchips.h  flash chip IDs
chipdrivers.h  chip-specific read/write/... functions
flash.h  common header for all stuff that doesn't fit elsewhere
hwaccess.h hardware access functions
programmer.h  programmer specific functions
coreboot_tables.h  header from coreboot, internal programmer only
spi.h SPI command definitions

1748c5701f Print an error message on read errors and abort instead of proceeding anyway
Improve error checking in file write, chip read and chip verify.
Refactor the read routines a bit to split reading from file writing.

Log for a failed read:
[...]
Found chip "Winbond W25x16" (2048 KB, SPI) at physical address
0xffe00000.
Reading flash... Invalid OPCODE 0x03
Read operation failed!
FAILED.

ad3cc55e13 Kill global variables, constants and functions if local scope suffices
Constify variables where possible.
Initialize programmer-related variables explicitly in programmer_init to
allow running programmer_init from a clean state after
programmer_shutdown.
Prohibit registering programmer shutdown functions before init or after
shutdown.
Kill some dead code.
Rename global variables with namespace-polluting names.
Use a previously unused locking helper function in sst49lfxxxc.c.

This is needed for libflashrom.

Effects on the binary size of flashrom are minimal (300 bytes
shrinkage), but the data section shrinks by 4384 bytes, and that's a
good thing if flashrom is operating in constrained envionments.

2db77a03ef Make the 'flashrom --help' output look a bit nicer
Only print "flashrom" as the program name unconditionally, not the full path
and program name (e.g. "/home/foo/bar/baz/flashrom" or on Windows
"C:\Foo\Bar\Whatever\flashrom.exe"). The path or exact executable name is
not really useful to print here, if you managed to run --help you already
know it, and it just makes the output look ugly.

Also, add a missing newline to make the output look nicer.

Finally, revert the "CONFIG_PRINT_WIKI ?= yes" change which accidentally
slipped into r1029.

71127727dc So far, we have up to 4 different names for the same thing (ignoring capitalization)
CONFIG_FT2232SPI (makefile config option)
FT2232_SPI_SUPPORT (#define)
ft2232spi (programmer name)
ft2232_spi.c (programmer file)

Use CONFIG_* with underscores for makefile config options and #defines
and kill the useless _SUPPORT idiom.
Use lowercase names with underscores for programmer names and programmer
files.

With this, you can run "grep -i ft2232_spi" and find everything related
to the ft2232_spi driver. Same applies to all other programmers.

831e8f4abb Remove unneeded #include statements completely
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.

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.

e7f3209487 Enable -Wshadow, clean code for that
This is not just for fun. We hit a real bug on BSD with the outl macros.
The macro variable tmp collided with the tmp from outer scope.

second revision, now also taking care of inb/inw/inl. While that shadowing
did not introduce bugs (yet), of course it breaks the build on BSD when
-Wshadow is enabled.

51e97d754f Converting fprintf(stderr), printf, and printf_debug into a common print interface for flashrom
It also changes so -VV will spit out highly verbose messages for
debugging. This is a minimal patch to lessen impact a later patch will
convert current printf messages to the new interface.

a84835a7ea Move the CLI related functions main() and cli_usage() to cli_classic.c
And rename them accordingly. For now, main() just calls cli_classic(),
but alternative frontends can be switched in main().
Annotate remaining help texts with CLI dependency inside flashrom.c with
a FIXME comment.

Now people can go and create different frontends and be happy. Please
note that any other frontend will have to sort of duplicate the probing
code in cli_classic.c. Refactoring that part of the code is possible,
but not easy because we still want to print instructive help messages
for users.
