      Various ichspi.c refinements · f041e9b5
      FENG yu ning authored 
      
* add a generic preop-opcode-pair table.

* rename ich_check_opcodes to ich_init_opcodes.

* let ich_init_opcodes do not need to access flashchip structure:
  . move the definition of struct preop_opcode_pair to a better place
  . remove preop_opcode_pairs from 'struct flashchip'
  . modify ich_init_opcodes and generate_opcodes so that they do not access the flashchip structure

* call ich_init_opcodes during chipset enable. Now OPCODES generation mechanism works.

* fix a coding style mistake.

      Check for failed SPI command execution · 598ec58e
      Carl-Daniel Hailfinger authored 
      
Although SPI itself does not have a mechanism to signal command failure,
the SPI host may be unable to send a given command over the wire due
to security or hardware limitations. The current code ignores these
mechanisms completely and simply assumes almost every command succeeds.
Complain if SPI command execution fails.

Since locked down Intel chipsets (like the one we had problems with
earlier) only allow a small subset of commands, find the common subset
of commands between the chipset and the ROM in the chip erase case. That
is accomplished by the new spi_chip_erase_60_c7() which can be used for
chips supporting both 0x60 and 0xc7 chip erase commands.

Both parts of the patch address problems seen in the real world. The
increased verbosity for the error case will help us diagnose and address
problems better.

      The AT25 and AT26 series SPI chips from Atmel are plain EEPROMs · d54ef6e7
      Carl-Daniel Hailfinger authored 
      
The AT45 series SPI chips are DataFlash EEPROMs which means they have
odd (non-power-of-two) sector sizes, but some of the DataFlash chips can
be configured or ordered with power-of-two sector sizes.

Add probe support for the following Atmel SPI chips:
AT25DF021
AT25DF041A
AT25DF081
AT25DF161
AT25DF321A
AT25DF641
AT25F512B
AT25FS010
AT25FS040
AT26DF041
AT26DF081A
AT26DF161
AT26DF161A
AT26DF321
AT26F004
AT45CS1282
AT45DB011D
AT45DB021D
AT45DB041D
AT45DB081D
AT45DB161D
AT45DB321C
AT45DB321D
AT45DB642D

Add an explanation why the following chips can't be probed:
AT45BR3214B
AT45D011
AT45D021A
AT45D041A
AT45D081A
AT45D161
AT45DB011
AT45DB011B
AT45DB021A
AT45DB021B
AT45DB041A
AT45DB081A
AT45DB161
AT45DB161B
AT45DB321
AT45DB321B
AT45DB642

Add the ID, but no probing function for this chip:
AT25F512A

      Winbond W39V040C and MSI K8T Neo2-F · cce2682d
      Peter Stuge authored 
      
W39V040C does standard JEDEC commands except chip erase so add a small driver.
probe_w39v040c() prints the block lock pin status when a chip is found.

The Neo2 board enable matches on 8237-internal IDE and onboard NIC PCI IDs.

Many thanks to Daniel McLellan for testing all of this on hardware!
Build tested by Uwe.

      Trivial SPI cleanups · f83221b6
      Peter Stuge authored 
      
While writing a new SPI driver I fixed some things in the SPI code:
All calls to spi_command() had unneccessary #define duplications, and in some
cases the read count define could theoretically become harmful because NULL was
passed for the read buffer. Avoid a crash, should someone change the #defines.

I also noticed that the only caller of spi_page_program() was the it87 driver,
and spi_page_program() could only call back into the it87 driver. Removed the
function for easier-to-follow code and made it8716f_spi_page_program() static.
The ichspi driver's static page functions are already static.

      Remove dead M-Systems Disk on Chip code · db52c58e
      Peter Stuge authored 
      
DOC support has been disabled by default for many years. The write function
does nothing but print text. It has a call to write_page_md2802() commented
out, but that function does not exist. This is dead code with ugly #ifdefs.

Updates README to reflect that there was a time when there was code, but it
didn't work. Removes M-Systems #defines and also includes svn rm msys_doc.*

      Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymore · b9f61744
      Jens Kuehnel authored 
      
Jens sent the first patch that added A49LF040A to flash.h and flashchips.c
using _jedec and _49lf040 functions.

An issue was found with probe_w29ee011() for the Winbond W29EE011, which
caused the A49LF040A to no longer respond to any commands.

Ward made a patch to disable probing by default for the W29EE011 following
some discussion. Using -c W29EE011 will make flashrom probe for the chip.

Peter did some more datasheet diving and found that the Pm49FL00x functions
suited this chip quite well because of the block locking registers in
A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3.

Ward confirmed that this works on alix.2c3 too.

      Force read unknown flash chips · 7ffbc6f9
      Peter Stuge authored 
      
When flash chip detection fails, it is still useful and possible to read the
flash chip contents. If no flash chip is found in normal probes and the
-f -r -c CHIPNAME options are given, a successful probe for the specified
chip is forced, and then flashrom reads the flash chip using either the read
function for the specified chip, or if there is none, a simple memcpy().

The patch also moves the global variable int force in flashrom.c into main()
and passes it as a parameter to layout.c:show_id(), which was the only other
function that used the variable. This is needed to avoid confusion with the
new parameter int force which is added to flashrom.c:probe_flash() and used
to force probe success for the chip named in char *chip_to_probe.
