Flashrom assumes that the flash chip contents are available via mmap if no read function is defined. This special case is handled in lots of places all over the code. Remove the special case and use the read_memmapped function. Not only does this allow us to fix a read bug in flashrom I recently uncovered on ICH SPI, it also allows us to add support for Paraflasher to flashrom. Corresponding to flashrom svn r473.

flashrom README
-------------------------------------------------------------------------------
flashrom is a utility for reading, writing, verifying and erasing flash ROM
chips. It's often used to flash BIOS/coreboot/firmware images.
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.
(see http://coreboot.org for details on coreboot)
Build Requirements
------------------
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
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 Solaris, use:
gmake LDFLAGS="-L$pathtolibpci -lpci -lz" CC="gcc -I$pathtopciheaders" \
CFLAGS=-O2
To compile on DragonFly BSD, use:
ln -s /usr/pkg/include/pciutils pci
gmake CFLAGS=-I. LDFLAGS="-L/usr/pkg/lib -lpci -lz"
To compile and run on Darwin/Mac OS X:
Install DirectIO from coresystems GmbH.
DirectIO is available at http://www.coresystems.de/en/directio.
