Currently spi_aai_write() is implemented without an abstraction
mechanism for the programmer driver. This adds another function
pointer 'write_aai' to struct spi_programmer, which is set to
default_spi_write_aai (renamed spi_aai_write) for all programmers
for now.
A patch which utilises this abstraction in the dediprog driver will
follow.

All programmer types (Parallel, SPI, Opaque) now register themselves
into a generic programmer list and probing is now programmer-centric
instead of chip-centric.
Registering multiple SPI/... masters at the same time is now possible
without any problems. Handling multiple flash chips is still unchanged,
but now we have the infrastructure to deal with "dual BIOS" and "one
flash behind southbridge and one flash behind EC" sanely.
A nice side effect is that this patch kills quite a few global variables
and improves the situation for libflashrom.
Hint for developers:
struct {spi,par,opaque}_programmer now have a void *data pointer to
store any additional programmer-specific data, e.g. hardware
configuration info.
Note:
flashrom -f -c FOO -r forced_read.bin
does not work anymore. We have to find an architecturally clean way to
solve this.

Struct flashchip is used only for the flashchips array and for
operations which do not access hardware, e.g. printing a list of
supported flash chips.
struct flashctx (flash context) contains all data available in
struct flashchip, but it also contains runtime information like
mapping addresses. struct flashctx is expected to grow additional
members over time, a prime candidate being programmer info.
struct flashctx contains all of struct flashchip with identical
member layout, but struct flashctx has additional members at the end.
The separation between struct flashchip/flashctx shrinks the memory
requirement of the big flashchips array and allows future extension
of flashctx without having to worry about bloat.

- probe_timing was changed to unsigned although we use negative values
for special cases
- some code was not changed along hence did no longer compile:
* dediprog's read and write functions
* linux_spi's read and write functions
- it introduced a number of new sign conversion warnings
(http://paste.flashrom.org/view.php?id=832)
To be safe this patch reverts all changes made in r1448, a corrected
patch will follow later.

Remove the array spi_programmer, replace it by dynamic registration
instead. Also initially start with no busses supported, and switch to
the default non-SPI only for the internal programmer.
Also this patch changes the initialization for the buses_supported variable
from "everything-except-SPI" to "nothing". All programmers have to set the
bus type on their own, and this enables register_spi_programmer to just add
the SPI both for on-board SPI interfaces (where the internal programmer
already detected the other bus types), as well as for external programmers
(where we have the default "none").

flashrom-chromium tree
This code has been deployed and tested to work on the Cr-48. There are a
few caveats, though: - The boot BIOS straps register must be modified to
select LPC. This can be done with the "select_bbs.sh" script (Install iotools
at http://code.google.com/p/iotools/ before using select_bbs). - It is very
important to disable power management daemons before running flashrom on
this EC. I commented out the brute force method we use in the Chromium OS
branch that disables powerd, since IIRC Carl-Daniel has a better approach in
the works. - Due to dependencies which may be introduced by the OEM/ODM EC
firmware, the code is not guaranteed to work for anything other than the Cr-48.
Carl-Daniel comments: Code is not hooked up yet because probing needs to
be sorted out.

flash programmer
The project is in the the process of designing and making a complete, open
source, graphics card. More info at http://wiki.opengraphics.org. The first
development card is a PCI add in card containing a couple of FPGAs and a couple
of serial flash chips (amongst other things). The FPGAs are called XP10 and S3
(their part numbers). The XP10 contains its own flash and does not need to be
programmed by flashrom - it ensures that the device can enumerate on the PCI
bus without needing further configuration. The larger FPGA is the S3. This is
configured from a large SPI flash (2 MBytes). The second SPI flash is used to
store the VGA BIOS. It is smaller (128 KBytes). This patch adds support for
programming either of the two SPI flash chips. The programmer device takes one
configuration option which selects which of the two flash chips is accessed.
This must be set to either "cprom" or "bprom". (The project refers to the two
chips as "cprom" / "bprom", "s3" and "bios" are more readable alternatives).
Add support for SST SST25VF010 (REMS). Mark SST SST25VF016B as tested for write.

drivers, but it was not entirely consistent
Some drivers had their own hand-rolled partial update functionality which made
handling partial updates from generic code impossible. Move implicit erase
out of chip drivers, and kill some dead erase functions at the same time.
A full chip erase is now performed in the generic code for all flash chips
on write, and after that the whole chip is written.

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.

flash.h common header for all stuff that doesn't fit elsewhere
hwaccess.h hardware access functions

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.

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.

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
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.

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].
