The currently used write functions (wrappers) all use helpers which perform the actual write (inner functions). The signature of the write wrappers is: int write_chip(struct flashchip *flash, uint8_t * buf); The signature of the inner write functions varied a lot. This patch changes them to: int write_part(struct flashchip *flash, uint8_t *src, int start, int len); Did you know that flashrom has only 8 inner write functions for all flash chips? write_page_write_jedec_common write_sector_jedec_common write_sector_28sf040 spi_chip_write_256_new spi_chip_write_1_new spi_aai_write_new write_page_82802ab write_page_m29f400bt Export all inner write functions. Change the function signature of wait_82802ab to eliminate single-use variables. Remove an error message in write_page_m29f400bt which was printed for every byte written regardless of success. Add sharplhf00l04.c to the list of flash chip drivers in the Makefile. While the functions in there are unused, I suspect we will need them later, and by hooking the file up we ensure that compilation won't break. Corresponding to flashrom svn r1208.

------------------------------------------------------------------------------- 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$SVNREVISION and will additionally modify the Makefile in that directory to contain the svn revision of the exported tree. make tarball will simply tar up the result of make export and gzip compress it. The snapshot tarballs are the result of make tarball and require no further processing. Build Instructions ------------------ To build flashrom you need to install the following software: * pciutils+libpci (if you want support for mainboard or PCI device flashing) * libusb (if you want FT2232 or Dediprog support) * libftdi (if you want FT2232 support) Linux et al: * pciutils / libpci * pciutils-devel / pciutils-dev / libpci-dev * zlib-devel / zlib1g-dev (needed if libpci was compiled with libz support) On FreeBSD, you need the following ports: * devel/gmake * devel/libpci On OpenBSD, you need the following ports: * devel/gmake * sysutils/pciutils To compile on Linux, use: make To compile on FreeBSD, use: gmake To compile on Nexenta, use: make To compile on Solaris, use: gmake LDFLAGS="-L$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 DirectHW from coresystems GmbH. DirectHW is available at http://www.coresystems.de/en/directhw . 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-4.3.2-8ap.i686.rpm djcrx-2.04pre_20090725-13ap.i386.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 and unpack http://homer.rice.edu/~sandmann/cwsdpmi/csdpmi7b.zip and make sure CWSDPMI.EXE is in the current directory. Processor architecture dependent features: On non-x86 architectures you have to disable a few programmers because they use port-based I/O which is not directly available on non-x86. Please add CONFIG_RAYER_SPI=no CONFIG_NIC3COM=no CONFIG_ATAHPT=no CONFIG_NICREALTEK=no \ CONFIG_NICNATSEMI=no as parameters to the "make" invocation. Besides that, the internal programmer is only supported on x86 and MIPS. On other architectures, please add CONFIG_INTERNAL=no as parameter to the "make" invocation. 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.
