* Allow one to disable programmer debug messages at compile timeCarl-Daniel Hailfinger2010-01-071-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Programmer debug messages during programmer init/shutdown are useful because they print hardware settings and desired configuration. They help in getting a quick overview of hardware and software state on startup and shutdown. Programmer debug messages during flash chip access are mostly a distraction in logs and should only be enabled if someone is having problems which are suspected to stem from a programmer hardware or programmer software bug. Disable those messages by default, they can be reenabled by #define COMM_DEBUG in the affected programmer file. An added benefit is a tremendous size reduction in verbose probe/read/write/erase logs because only flash chip driver messages remain. In some cases, logs will shrink from 65 MB to 10 kB or less. The right(tm) fix would be two different debug levels (DEBUG and SPEW) and the ability to differentiate between programmer debug messages and flash chip debug messages. Until the design for the message printing infrastructure is finished, this is the best stop-gap measure we can get. Corresponding to flashrom svn r834.

* Multiple unrelated changesPatrick Georgi2010-01-061-4/+2
| | | | | | | | | | | | | | | - replace the hand written serial input flush routine with the termios one. - serialport_discard_read isn't necessary anymore - it just wrapped sp_flush_incoming with no extra value. - serialport_read and serialport_write would misbehave if read or write didn't process everything in one go. - sp_flush_incoming should be #define'd out for FAKE_COMMUNICATION like serialport_discard_read was Corresponding to flashrom svn r831.

* Move OS-dependent serial code from buspirate_spi.c to serial.cCarl-Daniel Hailfinger2010-01-061-56/+4
| | | | | | | | | | While at it, also rename a few functions to make it obvious that they are generic and not specific to the Bus Pirate. Corresponding to flashrom svn r830.

* Add the ability to set Bus Pirate SPI speed via the command lineCarl-Daniel Hailfinger2009-11-241-20/+34
| | | | | | | | | | | | | | | | | | | | | | | Example usage: flashrom -p buspiratespi:spispeed=2.6MHz,dev=/dev/foo flashrom -p buspiratespi:dev=/dev/foo,spispeed=2.6M Refactor programmer option parsing (this allows cleanups in other programmers as well). Increase SPI read size from 8 to 12 bytes (current single-transaction limit of the Bus Pirate raw SPI protocol). Add Bus Pirate to the list of programmers supporting 4 byte RDID. Add Bus Pirate syntax to the man page. Tested-by: Sean Nelson <audiohacked@gmail.com> Corresponding to flashrom svn r776.

* Cleanly validate ICH SPI preopcodesCarl-Daniel Hailfinger2009-11-241-0/+358
The code should work on Linux/*BSD/MacOSX and relies on the serial code implementation in serial.c. Support for additional platforms (Windows) will have to be added to serial.c for this to work. For tests without a Bus Pirate (or with non-functional serial code) it is possible to #define FAKE_COMMUNICATION in buspirate_spi.c. Thanks to Sean Nelson for the SPI mode settings code. I tweaked it a bit to make configuration from a commandline easier should anybody want that feature. Tested-by: Sean Nelson <audiohacked@gmail.com> Corresponding to flashrom svn r772.
