      Add an internal DMI decoder · 4c6d3a4b
      Sean Nelson authored 
      
Previously we had to rely on dmidecode to decode the DMI/SMBIOS table.
This patch integrates a DMI decoder into flashrom. The old behavior of calling
dmidecode can be brought back by using CONFIG_INTERNAL_DMI=no.

Significant portions of this patch were taken from dmidecode, hence add its
authors to the copyright notice (dmidecode is also GPL2+). We do a few things
differently though. First of all we do more bounds checking to prevent accessing
unmapped memory. We do not support disovery via EFI (yet), but memory
scanning only. We handle the chassis-type lock bit correctly which dmidecode
did not for a long while.

The API to the rest of flashrom remains stable, but the output changes slightly.
To share as much code as possible (which actually is not much), i have added
dmi_fill methods that get called in dmi_init. They are reponsible to fill the
dmi_strings array and setting the is_laptop variable. After it is called, dmi_init
prints all dmi_strings. Previously the strings were printed in the order they were
discovered, followed by the chassis-type, which is now output earlier (in dmi_fill).

Because DJGPP does not support strnlen a simple implementation was added
for it.

This is still only available on x86; actually it is not even compiled in for other
architectures at all anymore.

      DOS refinements · 449abe28
      Stefan Tauner authored 
      
This allows to use the DOS library trees stored in a user-specified directory.

I have mirrored the needed patches, sources and binaries (the latter
are properly licensed to allow that) in the flashrom wiki, so use those
URLs instead of the original sources.

      Automatically add version and date to the manpage · a93d9dc5
      Joerg Mayer authored 
      
To avoid funny effects of ever changing files tracked by the VCS this patch
moves the manpage data to flashrom.8.tmpl and generates the actual
manpage with a new makefile target if needed.

      Improve getrevision.sh · ec7a35f7
      Stefan Tauner authored 
      
 - remove bashism.
 - simplify some git-related code.
 - improved parameter and error handling.
 - additional -d/--date action which is similar to the timestamp action.
 - support for an optional path parameter.
 - there is only one sane time format.
 - and only one sane date format too.
 - use UTC dates and times only.
 - vastly improve git_url() to print the correct remote url and
   "nearest" branch.
 - remove username from repository URLs.
 - add "-dirty" to local revisions if there are uncommitted changes.
 - indicate in local revisions how many git-only commits were done
   since branching from upstream svn.
 - fix svn_revision() fallback to svn info and remove git-svn.
 - print leading r in script instead of hardcode it in the makefile;
   no more "0.9.7-runknown".
 - make retrieving the upstream revision work even in cloned git-svn
   repositories.
 - more abstractions and helper functions.
 - less fragmentation of actual functionality.

      Improve SPI status register pretty printing · 6ee37e28
      Stefan Tauner authored 
      
 - Move all functions related to SPI status registers to a new file
   spi25_statusreg.c. This includes the generic as well as the
   SST-specific functions from spi25.c and the chip-specific functions
   from a25.c and at25.c.
 - introduce helper functions
    * spi_prettyprint_status_register_hex()
    * spi_prettyprint_status_register_bpl()
    * spi_prettyprint_status_register_plain()
   Use the latter on every compatible flash chip that has no better printlock
   function set and get rid of the implicit pretty printing in the SPI probing
   functions.
 - remove
    * spi_prettyprint_status_register_common()
    * spi_prettyprint_status_register_amic_a25lq032() because it can be fully
      substituted with spi_prettyprint_status_register_amic_a25l032().
    * spi_prettyprint_status_register() (old switch, no longer needed)
 - promote and export
    * spi_prettyprint_status_register_amic_a25l05p() as spi_prettyprint_status_register_default_bp1().
    * spi_prettyprint_status_register_amic_a25l40p() as spi_prettyprint_status_register_default_bp2().
    * spi_prettyprint_status_register_st_m25p() as spi_prettyprint_status_register_default_bp3().
 - add #define TEST_BAD_REW and use it for a number of Atmel chips which
   had only TEST_BAD_READ set even though they dont have erasers or a write
   function set.

      Cross-compilation fixes · 33a65a06
      Carl-Daniel Hailfinger authored 
      
Switch from host OS detection to target OS detection.
Complain about unknown target OS/architecture.
Disable annoying format string warnings on DJGPP.

Native and cross-compilation now usually just require setting CC.
Examples:
make CC=i586-pc-msdosdjgpp-gcc
make CC="clang -m64"
make CC=i686-w64-mingw32-gcc

Tested for a boatload of native and cross compilation configurations.

There is a new target "make libpayload" in case you don't want to
specify all tools by hand.

      ichspi: add ICH/PCH flash descriptor decoding via FDOC/FDOD · 1e14639f
      Stefan Tauner authored 
      
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.

      Makefile: Fix MinGW build, improve output with bogus CC · 44ffd58a
      Uwe Hermann authored 
      
As per IRC discussion, the "ARCH :=" line should be moved after any
lines which set CC, as it uses CC itself. This fixes the MinGW build.

Also, add a "2>/dev/null" in the "ARCH :=" as per suggestion from
Stefan Tauner to improve the output in the case CC is bogus:

Before:
$ make CC=foo
/bin/sh: foo: not found
Checking for a C compiler... not found.
make: *** [compiler] Error 1

After:
$ make CC=foo
Checking for a C compiler... not found.
make: *** [compiler] Error 1
