* Add struct flashctx * parameter to all functions accessing flash chipsCarl-Daniel Hailfinger2011-12-181-6/+12
| | | | | | | | | | | | | | | | All programmer access function prototypes except init have been made static and moved to the respective file. A few internal functions in flash chip drivers had chipaddr parameters which are no longer needed. The lines touched by flashctx changes have been adjusted to 80 columns except in header files.

* Use struct flashctx instead of struct flashchip for flash chip accessCarl-Daniel Hailfinger2011-12-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | Struct flashchip is used only for the flashchips array and for operations which do not access hardware, e.g. printing a list of supported flash chips. struct flashctx (flash context) contains all data available in struct flashchip, but it also contains runtime information like mapping addresses. struct flashctx is expected to grow additional members over time, a prime candidate being programmer info. struct flashctx contains all of struct flashchip with identical member layout, but struct flashctx has additional members at the end. The separation between struct flashchip/flashctx shrinks the memory requirement of the big flashchips array and allows future extension of flashctx without having to worry about bloat.

* Add support for the Linux SPI subsystem (spidev)Sven Schnelle2011-09-031-0/+139
See http://www.kernel.org/doc/Documentation/spi/spidev for an introduction. Usage is as follows: flashrom -p linux_spi:dev=/dev/spidevX.Y where X is the bus number, and Y device. It accepts an optional parameter 'speed' which allows to set the SPI clock speed in kHz. Tested on an Atmel AVR32AP7000 board (NGW100 Network Gateway Kit), see below, which was used to program a ThinkPad X60, but it should work on every other Linux system, too. http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4102) Corresponding to flashrom svn r1427.
