| | | | | | | | | | | | | | | | | | | not deal with a Bus Pirate which is already in binary Bitbang mode. This is caused by a combination of the slowness of the Bus Pirate, the slowness of USB and a fast serial port flush routine which just flushes the buffer contents and does not wait until data arrival stops. Make the Bus Pirate init more robust by running the flush command 10 times with 1.5 ms delay in between. This code development was sponsored by Mattias Mattsson. Thanks! Tested a few dozen times, should work reliably.

| | | | | | | | | | | | | | | | | Pirate (namely, waiting for the completion of one command before sending the next one), we can reduce the number of round trips by a factor of 3. The FT2232 chip present in the Bus Pirate has a big enough buffer (at least 128 bytes IIRC) to avoid overflows in the tiny buffer of the Bus Pirate PIC. Thanks to Daniel Flinkmann for sponsoring development of this patch.

| | | | | | | | | | | | | | | | | | | | | | Programmer specific functions are of absolutely no interest to any file except those dealing with programmer specific actions (special SPI commands and the generic core). The new header structure is as follows (and yes, improvements are possible): flashchips.h flash chip IDs chipdrivers.h chip-specific read/write/... functions flash.h common header for all stuff that doesn't fit elsewhere hwaccess.h hardware access functions programmer.h programmer specific functions coreboot_tables.h header from coreboot, internal programmer only spi.h SPI command definitions Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: https://code.coreboot.org/svn/flashrom/trunk@1112 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

This led to wildly differing syntax for programmer parameters, and it also voids pretty much every assumption you could make about programmer_param. The latter is a problem for libflashrom.

* Kill global variables, constants and functions if local scope suffices.hailfinger2010-07-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Constify variables where possible. Initialize programmer-related variables explicitly in programmer_init to allow running programmer_init from a clean state after programmer_shutdown. Prohibit registering programmer shutdown functions before init or after shutdown. Kill some dead code. Rename global variables with namespace-polluting names. Use a previously unused locking helper function in sst49lfxxxc.c. This is needed for libflashrom. Effects on the binary size of flashrom are minimal (300 bytes shrinkage), but the data section shrinks by 4384 bytes, and that's a good thing if flashrom is operating in constrained envionments.

* Programmer debug messages during programmer init/shutdown are usefulhailfinger2010-01-071-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add Bus Pirate SPI support to flashrom.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.
