Change SPI architecture to handle 1-byte chunk chip writing differently from 256-byte chunk chip writing. Annotate SPI chip write functions with _256 or _1 suffix denoting the number of bytes they write at maximum. The 1-byte chunk writing is cut-n-pasted to different SPI drivers right now. A later patch can move them to the generic spi_chip_write_1. Corresponding to flashrom svn r485.

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.
