Convert all PCI-based external programmers to use special little-endian accessors for all MMIO regions of PCI devices. This patch does _not_ touch the internal programmer (which is PCI-based as well). Huge thanks go to Misha Manulis who worked with me to create a first version of this patch for the satasii programmer based on modification of generic code. Huge thanks also go to Segher Boessenkool for suggesting the pci_mmio_ prefix for the abstraction layer. NOTE to package maintainers: With this patch, compilation and usage of flashrom should be safe on x86, x86_64, MIPS (little and big endian) and PowerPC (big endian). The internal programmer is disabled on non-x86/x86_64 (but it compiles). The atahpt, nic3com, nicnatsemi, nicrealtek and rayer_spi can not be compiled on non-x86/x86_64 because port space I/O is not (yet) supported. Please compile with default settings on x86/x86_64 and with the following settings on all other architectures: make CONFIG_NIC3COM=no CONFIG_NICREALTEK=no CONFIG_NICNATSEMI=no CONFIG_RAYER_SPI=no Corresponding to flashrom svn r1111.

------------------------------------------------------------------------------- flashrom README ------------------------------------------------------------------------------- flashrom is a utility for detecting, reading, writing, verifying and erasing flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images in-system using a supported mainboard, but it also supports flashing of network cards (NICs), SATA controller cards, and other external devices which can program flash chips. It supports a wide range of DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, and TSOP40 chips, which use various protocols such as LPC, FWH, parallel flash, or SPI. Do not use flashrom on laptops! The embedded controller (EC) present in many laptops interacts badly with any flash attempts and can brick your laptop permanently. Please make a backup of your flash chip before writing to it. Please see the flashrom(8) manpage. Packaging --------- To package flashrom and remove dependencies on subversion, either use make export or make tarball make export will export all flashrom files from the subversion repository at revision BASE into a directory named $EXPORTDIR/flashrom-$VERSION-r$SVNREVISION and will additionally modify the Makefile in that directory to contain the svn revision of the exported tree. make tarball will simply tar up the result of make export and gzip compress it. The snapshot tarballs are the result of make tarball and require no further processing. Build Instructions ------------------ To build flashrom you need to install the following packages or ports: Linux et al: * pciutils / libpci * pciutils-devel / pciutils-dev / libpci-dev * zlib-devel / zlib1g-dev (needed if libpci was compiled with libz support) On FreeBSD, you need the following ports: * devel/gmake * devel/libpci On OpenBSD, you need the following ports: * devel/gmake * sysutils/pciutils To compile on Linux, use: make To compile on FreeBSD, use: gmake To compile on Nexenta, use: make To compile on Solaris, use: gmake LDFLAGS="-L$pathtolibpci" CC="gcc -I$pathtopciheaders" CFLAGS=-O2 To compile on NetBSD or DragonFly BSD, use: ln -s /usr/pkg/include/pciutils pci gmake CPPFLAGS=-I. LDFLAGS="-L/usr/pkg/lib -Wl,-rpath-link,/usr/pkg/lib" To compile on OpenBSD, use: gmake To compile and run on Darwin/Mac OS X: Install DirectIO from coresystems GmbH. DirectIO is available at http://www.coresystems.de/en/directio. To cross-compile on Linux for DOS: Get RPMs of the cross compiler from the DJGPP site and install them: djcross-binutils-2.19.1-10ap.i386.rpm djcross-gcc-tools-4.4.1-1ap.i686.rpm djcross-gcc-4.3.2-8ap.i686.rpm Download pciutils 3.1.5 and apply http://assembler.cz/flashrom/pciutils.patch Download and compile http://assembler.cz/flashrom/libgetopt/ Compile pciutils, see README.DJGPP for instructions. Enter the flashrom directory. ../libpci should contain pciutils source and binaries. ../libgetopt should contain getopt.a from libgetopt. Run either (change settings where appropriate) make CC=i586-pc-msdosdjgpp-gcc STRIP=i586-pc-msdosdjgpp-strip OS_ARCH=DOS or (above settings hardcoded) make djgpp-dos You might have to add WARNERROR=no to the make command line. To run flashrom.exe, download http://clio.rice.edu/djgpp/csdpmi7b.zip and make sure CWSDPMI.EXE is in the current directory. Installation ------------ In order to install flashrom and the manpage into /usr/local, type: make install For installation in a different directory use DESTDIR, e.g. like this: make DESTDIR=/usr install If you have insufficient permissions for the destination directory, use sudo by adding sudo in front of the commands above.
