Until the ICH SPI driver can handle preopcodes as standalone opcodes, we should handle such special opcode failure gracefully on ICH and compatible chipsets. This fixes status register writes on almost all ICH+VIA SPI masters. The fix is almost identical to r484, but this time it affects the EWSR (Enable Write Status Register) opcode instead of the WREN (Write Enable) opcode. With the differentiated return codes introduced in r500, the workaround is more precise this time. The old WREN workaround was updated as well. Corresponding to flashrom svn r514.

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.
