* Introduce enum test_stateStefan Tauner2012-07-281-2/+5
| | | | | | | | | | | | | | | | Previously boards in the wiki were tagged either as working or as known bad. But we added support to various boards via board enables that were then never tested because the owners have not reported back. This can now be tagged with NT and is shown appropriately. Also, the underlying data structure indicating state was converted from macros to an enum while preserving original integer values and is used for programmers and chipsets too.

| | | | | | | | | | | | | Move hwaccess.h #include from flash.h to individual drivers. libflashrom users need flash.h, but they do not care about hwaccess.h and should not see its definitions because they may conflict with other hardware access functions and #defines used by the libflashrom user.

* Bus Pirate buffer management revampCarl-Daniel Hailfinger2012-06-081-0/+1
| | | | | | | | | | | | | The buffer management of the Bus Pirate driver has been revamped to use grow-only buffers with a reasonable initial default size so realloc() will not have to be called in normal operation. A side effect is the ability to switch to a static buffer without major hassle. Handle OOM gracefully. Corresponding to flashrom svn r1541.

* Add support for SFDP (JESD216)Stefan Tauner2012-02-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to modules using the opaque programmer framework (e.g. ICH Hardware Sequencing) this uses a template struct flashchip element in flashchips.c with a special probe function that fills the obtained values into that struct. This allows yet unknown SPI chips to be supported (read, erase, write) almost as if it was already added to flashchips.c.

* Warn of one-time programmable (OTP) memoryDaniel Lenski2012-02-151-0/+1
| | | | | | | | | | | | | | | | | | Some flash chips contain OTP memory that we cannot read or write (yet). This prohibits us from cloning them, hence warn the user if we detect it. Not all variations of the tagged chips contain OTP memory. They are often only enabled on request or have there own ordering numbers. There is usually no way to distinguish them. Because this is a supposedly seldomly used feature the warning is shown in with dbg verbosity. The manpage is extended to describe the backgrounds a bit. Corresponding to flashrom svn r1493.

* Have all programmer init functions register bus masters/programmersCarl-Daniel Hailfinger2011-12-201-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | All programmer types (Parallel, SPI, Opaque) now register themselves into a generic programmer list and probing is now programmer-centric instead of chip-centric. Registering multiple SPI/... masters at the same time is now possible without any problems. Handling multiple flash chips is still unchanged, but now we have the infrastructure to deal with "dual BIOS" and "one flash behind southbridge and one flash behind EC" sanely. A nice side effect is that this patch kills quite a few global variables and improves the situation for libflashrom. Hint for developers: struct {spi,par,opaque}_programmer now have a void *data pointer to store any additional programmer-specific data, e.g. hardware configuration info. Note: flashrom -f -c FOO -r forced_read.bin does not work anymore. We have to find an architecturally clean way to solve this. Corresponding to flashrom svn r1475.

* Use struct flashctx instead of struct flashchip for flash chip accessCarl-Daniel Hailfinger2011-12-141-16/+40
| | | | | | | | | | | | | | | | | | | | | | 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.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch attempts to resolve some programmer shutdown ordering issues by having the programmer init functions register shutdown callbacks explicitly wherever it makes most sense. Before, assumptions were made that could lead to the internal programmer's state changing before the external programmer could be shut down properly. Now, each programmer cleans up after itself and (hopefully) performs each operation in the correct order. As a side-effect, this patch gives us a better usage model for reverse operations such as rpci_* and rmmio_*. In the long-run, this should make reversing the initialization process easier to understand, less tedious, and less error-prone. In short, this patch does the following: - Registers a shutdown callback during initialization for each programmer. - Kills the .shutdown function pointer from programmer_entry struct. Also, make most shutdown functions static. - Adds a few minor clean-ups and corrections (e.g. missing physunmap() calls).

* Refine SPI bitbangingCarl-Daniel Hailfinger2010-07-171-5/+1
| | | | | | | | | | | | | | | Change the SPI bitbanging core to fix a subtle bug (which had no effect so far) and to make integration of the RayeR SPIPGM and Nvidia MCP6x/MCP7x SPI patches easier. Kill a few global variables and require explicit initialization of bitbanging delay. A big to Johannes Sjölund for testing an earlier version of the code as part of the Nvidia MCP6x/MCP7x SPI bitbanging patch. Corresponding to flashrom svn r1085.
