Since many commands take around 10 microseconds to complete, it is totally pointless to wait for 1000 microseconds before checking the status again. This patch is tested and reduced write time on ICH7 with SST25VF080B from over one hour to 62 seconds. Thanks to Ali Nadalizadeh for testing! Corresponding to flashrom svn r487.

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.
