coreboot build environment for windows

09/03/2010 win-build-env-001.7z - original

Target cross compilers are now built using the 'coresystems cross toolchain builder v1.01' tool.
Add target compiler version 4.4.4 in addition to version 4.5.0. Edit line 21 of go.bat to select the compiler.
Add python tool needed to build the seabios payload.
Add yes command needed by the abuild utility.
Ensure that all coreboot projects can build using this build environment.
Note: to run abuild, you must copy the xgcc directory from msys\gcc450 to coreboot\util\crossgcc.

Add --with-dwarf2 to the gcc configure command. This makes gcc -g produce dwarf2 debugging information.
Correct an improperly formed comment in go.bat.
Update the sample coreboot to revision 5991 and test this build environment using abuild.

Add gcc 4.5.1 cross compiler. Versions 4.4.4 and 4.5.0 are still included. Built with this patch applied to buildgcc rev 5768, plus add --with-dwarf2 and --enable-lto to gcc configure.
Change go.bat default cross compiler from version 4.5.0 to version 4.5.1.
Completely ignore Path environment variable when building to ensure only the indended build tools are executed.
Change go.bat to locate the msys directory using an environment variable (msys_for_coreboot) instead of using a relative path. This simplifies archiving projects independently of the build environment.
Move tools directory into the msys directory so that a single environment variable locates everything needed to build a coreboot project.
Update iasl.exe from version version 20100806 to version 20101013.
Update m4.exe from version 1.4.7 to version 1.4.14.
Add bison/flex/yacc.
Update the sample coreboot to revision 6098.

The included mingw is modified for compatibility with the seabios kconfig tool build:
- stdio.h and io.h prototypes for mkdir allow a second argument.
- stdio.h and io.h redefine the rename function to rpl_rename.
- libmingw32.a is expanded to include libregex.dll.a and libws2_32.a.
- libmingw32.a is expanded to include rpl_rename and uname functions from gnulib.
- See msys\mingw-msys-modifications\readme.txt for details.
- WARNING: use this build environment for coreboot build only. Use a standard msys/mingw build environment for crossgcc or other builds.
The included msys-1.0.dll is modified to avoid "Couldn't commit memory for cygwin heap" error during AMD family 14h builds.
Add gcc 4.5.2 cross compiler. Version 4.4.4 is still included. Version 4.5.2 is built with buildgcc rev 6195, plus --with-dwarf2 to gcc configure.
Change go.bat default cross compiler to version 4.5.2.
Update the sample coreboot to revision 6474.
Abuild tested with svn://coreboot.org/coreboot/trunk rev 6474 (Note: to run abuild, you must copy the xgcc directory from msys\gcc452 to coreboot\util\crossgcc).

Change gcc version in go.bat from 4.6.0 to 4.5.2 for compatibility with existing coreboot projects.

Add gcc 4.62 cross compiler. Built using this msys and these buildgcc changes (see included buildgcc):
- --with-dwarf2 (makes debug output without modification to the makefiles)
- --enable-frame-pointer (restore gcc 4.5.x default to reduce code size)
Change go.bat default cross compiler to version 4.6.2.
Update iasl.exe to latest version.
Add go.bat IASL definition to avoid build fail with newer coreboot revisions.
Make go.bat look for msys in parent and current directories. This eliminates the need the msys_for_coreboot variable.
