I disassembled the write enable and the write disable functions from
the Award BIOS image and reconstructed C code to understand for

I compared the download pages of both, abit AV8 and abit AV8-3rd Eye,
and the BIOS downloads are the same. So it's save to assume that this

http://www.goepel.com/en/jtagboundary-scan/hardware/picotap.html
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.htmlhttp://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.

Based on the work of Matthias 'mazzoo' Wenzel this patch adds pretty
printing of those ICH/PCH flash descriptor sections that are
cached/mapped by the chipset (and which are therefore reachable via
FDOC/FDOD registers).
this includes the following:
- content section:
describes the image and some generic properties (number of
sections, offset of sections, PCH/ICH and MCH/PROC strap
offsets and lengths)
- component section:
identify the different SPI flash chips and their capabilities.
- region section
similarly to a partition table this describes the different regions.
the content of FLREG* is derived from this section.
- master section
defines SPI master (host, ME, GbE) access rights of the
individual regions. the content of PR* is derived from this section.
this is only a part of the data included in the descriptor. other
information can be retrieved from a complete binary dump of the
descriptor region only.
this patch also adds macros and pretty printing for "Vendor Specific
Component Capabilities" registers: there are two of them: lower and
upper. they describe the properties of the address space divided by
FPBA (which allows to use multiple flash chips or partitions with
different properties). the properties of all supported flash chips
(together with their RDIDs) are stored in the same format in table
in a descriptor section (which is used by the ME apparently). a
later patch will use the macros outside of ichspi.c which is the
reason why the prettyprinting function and the register bit macros
are not defined in ichspi.c but ich_descriptors.h (else they would
be moved in the follow-up patch).
because this patch relies on (compiler) implementation-specific
layouting of bit-fields, it checks for correct layout before taking
any action on runtime.

The meaning of the bits involved has changed several times in the past.
This patch takes these changes into account and hence fixes the output of the
pretty printing of GCS on all SPI-supported Intel chipsets that are not ICH7 or
NM10 (the latter were unaffected, because the defaults were correct).
This patch also allows to differentiate Ibex Peak and Cougar Point chipsets from
the earlier chipset series (ICH10) by adding new wrapper functions that set
"ich_generation" to 11 and 12 respectively. This should not change behavior
outside of enable_flash_ich_dc_spi, because the code path for
ich_generation >=9 is equal.
alternatively we could just remove the pretty printing of GCS and just output
the bits involved. i would like to keep the pch differentiation anyway though,
because i feel it will become handy in the future.

This was totally broken due to the make's shell function's temporal
behavior.
quote from the gnu make documentation
(http://www.gnu.org/s/hello/manual/make/Shell-Function.html):
"The commands run by calls to the shell function are run when the
function calls are expanded"
we have used the shell function to echo the test programs to a file.
the file name used was equal for all tests and was overwritten for
each test. the result was that all tests (in a single target?) used
the last test program because the echoing of the test programs was
done before all test compilations(!)
see my mail for details:
http://lists.gnu.org/archive/html/bug-make/2011-08/msg00010.html
also the branching for testing ifeq ($(CONFIG_FT2232_SPI), yes) was
unnecessarily complicated.
in my approach here i am using verbatim variables (allows to define
even complex test programs in the makefile without jumping through
hoops) that get exported to environment variables (via "export",
reference afterwards with "$$<varname>").
i have also added the missing redirection of stderr to the compiler
test and changed the definition of ARCH to use simple expansion (:=).
the latter is still wrong, because it uses $(CC) before we check if
a compiler is installed... makes the compiler check pretty much
useless. The simple expansion just reduces the number of errors
printed to 1.
