      SPI command black-/ignorelisting for the flash chip emulator in the dummy programmer · 1b83be5c
      Carl-Daniel Hailfinger authored 
      
Usage:
flashrom -p dummy:spi_blacklist=commandlist
flashrom -p dummy:spi_ignorelist=commandlist

If commandlist is 0302, flashrom will refuse (blacklist) or ignore
(ignorelist) command 0x03 (READ) and command 0x02 (WRITE). The
commandlist can be up to 512 bytes (256 commands) long.
Specifying flash chip emulation is a good idea to get useful results.

Very useful for testing corner cases if you don't own a locked down
Intel chipset and want to simulate such a thing.

Example usage:
dd if=/dev/zeros bs=1024k count=4 of=dummy_simulator.rom
dd if=/dev/urandom bs=1024k count=4 of=randomimage.rom
flashrom -p dummy:emulate=SST25VF032B,image=dummy_simulator.rom,\
spi_blacklist=20,spi_ignorelist=52 -w randomimage.rom -V

Corresponding to flashrom svn r1490.

      Add ich_descriptor_tool to decode all flash descriptors stored in a flash dump file · b3850964
      Stefan Tauner authored 
      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...

      Use struct flashctx instead of struct flashchip for flash chip access · 63fd9026
      Carl-Daniel Hailfinger authored 
      
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.

      ichspi: use a variable to distinguish ich generations instead of spi_programmer->type · a8d838d9
      Stefan Tauner authored 
      The type member is enough most of the time to derive the wanted
information, but
 - not always (e.g. ich_set_bbar),
 - only available after registration, which we want to delay till the
   end of init, and
 - we really want to distinguish between chipset version-grained
   attributes which are not reflected by the registered programmer.

Hence this patch introduces a new static variable which is set up
early by the init functions and allows us to get rid of all "switch
(spi_programmer->type)" in ichspi.c. We reuse the enum introduced
for descriptor mode for the type of the new variable.

Previously magic numbers were passed by chipset_enable wrappers. Now
they use the enumeration items too. To get this working the enum
definition had to be moved to programmer.h.

Another noteworthy detail: previously we have checked for a valid
programmer/ich generation all over the place. I have removed those
checks and added one single...

      Fix all ASUS P5GD* board enables · a4f1447e
      Stefan Tauner authored 
      Changes related to P5GD1 variants:
- Reorder "P5GD1 Pro" in print.c and include a DMI patter to its board enable
- Add an untested "P5GD1(-VM)" board enable and add an entry to print.c
- Add P5GD1-VM/S variant as reported by "Limer"

Changes related to P5GD(2/C) variants:
- Fix the name of "P5GDC-V Deluxe" board enable and add a DMI pattern and
  print.c entry. NB: there is no "P5GDC-V" board.
- Add a generic match for P5GD(2/C)* boards with a not tested tag.
  This are the potential targets for this according to the asus ftp:
  ftp://ftp.asus.com.tw/pub/ASUS/mb/socket775/
   Unsupported variants of the P5GD2:
    P5GD2, P5GD2 Deluxe, P5GD2 Pro, P5GD2-X
    (P5GD2 Premium is already tested)
    (there seems to be also a P5GD2-TVM/GB/SI in the wild, which is not known to
    asus :)
   Unsupported variants of the P5GDC:
   P5GDC Pro, P5GDC-MX
    (P5GDC Deluxe and P5GDC-V Deluxe are already tested)
