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.


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
 * pciutils-devel / pciutils-dev / libpci-dev
 * zlib-devel / zlib1g-dev (only needed if libpci is static)

On FreeBSD, you need the following ports:

 * devel/gmake
 * devel/libpci

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 DragonFly BSD, use:

 ln -s /usr/pkg/include/pciutils pci
 gmake CFLAGS=-I. LDFLAGS="-L/usr/pkg/lib"

To compile and run on Darwin/Mac OS X:

 Install DirectIO from coresystems GmbH.
 DirectIO is available at http://www.coresystems.de/en/directio.


Installation
------------

In order to install flashrom and the manpage into /usr/local, type:

 sudo make install

For installation in a different directory use DESTDIR, e.g. like this:

 sudo make DESTDIR=/usr install
