The core of this patch to support Bay Trail originally came from the
Chromiumos flashrom repo and was modified by Sage to support the
Rangeley/Avoton parts as well.
Because that was not complicated enough already Stefan Tauner refactored
and refined everything. Bay Trail seems to be the first Atom SoC able to
support hwseq. No SPI Programming Guide could be obtained so it is
handled similarly to Lynx Point which seems to be its nearest relative.

Possible values as well as encodings have changed in newer chipsets as follows.
 - Pre-PCH (i.e. ICH) chipsets had a maximum frequency of 33 MHz for all
   operations
 - Since Cougar Point the chipsets support dual output fast reads (encoded
   in bit 30).
 - Flash component density encoding has changed from 3 to 4 bits with Lynx
   Point, currently allowing for up to 64 MB chips.

This allows to list yet unsupported chips easily.

First it tries to find the directory containing the files, then it uses sed to
extract the macro names of chips from flashchips.h, greps for them in
flashchips.c and prints it if it is not found.
If verbose mode is activated by giving at least one additional parameter
it prints the chip ID and comment following the macro definition too.

GNU make has a very interesting quirk: If you set a variable on the
command line, any changes to that variable in the Makefile are ignored
unless marked with the "override" keyword.

Use CFLAGS only for optimization and warning options, and use CPPFLAGS
for the dependency and other preprocessor related options.
That way packagers can specify their own CFLAGS without breaking the
build.

As a side benefit, the ich_descriptors_tool Makefile now behaves exactly
the same whether called standalone or as part of the main Makefile.

This patch adds an external utility that shares most of the existing descriptor
decoding source code. Additionally to what is available via FDOC/FDOD this
allows to access:
 - the softstraps which are used to configure the chipset by flash content
   without the need for BIOS routines. on ICH8 it is possible to read those
   with FDOC/FDOC too, but this was removed in later chipsets.
 - the ME VSCC (Vendor Specific Component Capabilities) table. simply put,
   this is an SPI chip database used to figure out the flash's capabilities.
 - the MAC address stored in the GbE image.

Intel thinks this information should be confidential for ICH9 and up, but
references some tidbits in their public documentation.
This patch includes the human-readable information for ICH8, Ibex Peak
(5 series) and Cougar Point (6 series); the latter two were obtained from
leaked "SPI Flash Programming Guides" found by google. Data regarding ICH9
and 10 is unknown to us yet. It can probably found in:
"Intel® ICH7, ICH8, ICH9 and ICH10 — SPI Family Flash Programming Guide"
Information regarding the upcoming Panther Point chipset is also not included.

This device is actually a JTAG adapter, but since it uses standard
FT2232 A interface pins, it can be easily used as SPI programmer
(tested it here successfully). PicoTAP supports only 5V output, so one
needs to reduce this to 3.3V in a same manner as DLP Design DLP-USB1232H, see

  http://flashrom.org/FT2232SPI_Programmer#DLP_Design_DLP-USB1232H



for details.

The PicoTAP pin-out is as follows:

  PicoTAP |  SPI
 ---------+-------
    TCK   | SCLK
    TMS   |  CS#
    TDI   |  SO
    TDO   |  SI
   /TRST  |  -
    GND   |  GND
    +5V   |  VCC, HOLD# & WP# after 3.3V regulator

I managed to run PicoTAP in 10MHz, 15MHz and 30MHz modes (by forcing
DIVIDE_BY), against SST25VF016B SPI flash, read/write/erase all worked
fine (write seems somewhat slow).

Thanks to TIAO/DIYGADGET for sponsoring a test device!

This is an FTDI FT2232H based device which provides an easily accessible JTAG,
SPI, I2C, serial breakout. The SPI part can be used to flash SPI flash chips
using flashrom.

http://www.diygadget.com/tiao-usb-multi-protocol-adapter-jtag-spi-i2c-serial.html
http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_User%27s_Manual#SPI_Connector_1



There are two SPI connectors (pin headers) on the board: SPI1, which is
connected to the FT2232H's A interface, and SPI2, which is connected to the
chip's B interface. Both can be used to flash SPI chips:

 flashrom -p ft2232_spi:type=tumpa,port=A
 flashrom -p ft2232_spi:type=tumpa,port=B

The default interface is A, so for SPI1 you can also just write:

 flashrom -p ft2232_spi:type=tumpa

I tested all operations on both interfaces, everything works fine.
