* Revert "Unsignify lengths and addresses in chip functions and structs"Stefan Tauner2011-09-181-2/+2
| | | | | | | | | | | | | | | | | | | | - probe_timing was changed to unsigned although we use negative values for special cases - some code was not changed along hence did no longer compile: * dediprog's read and write functions * linux_spi's read and write functions - it introduced a number of new sign conversion warnings (http://paste.flashrom.org/view.php?id=832) To be safe this patch reverts all changes made in r1448, a corrected patch will follow later. Thanks to idwer for pointing out the problem first! Corresponding to flashrom svn r1450.

* Add support for the Linux SPI subsystem (spidev)Sven Schnelle2011-09-031-0/+21
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | The file flashrom.c is part of libflashrom and should thus not contain a main() function, that would break compilation of all frontends using libflashrom. Also, cli_classic.c is the right place anyway, as it's the main() of the CLI tool. Rename the simple wrapper cli_classic() in cli_classic.c to main(), as it's not really needed.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-22/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Kill central list of SPI programmersMichael Karcher2011-05-111-8/+1
| | | | | | | | | | | | | | | | | | Remove the array spi_programmer, replace it by dynamic registration instead. Also initially start with no busses supported, and switch to the default non-SPI only for the internal programmer. Also this patch changes the initialization for the buses_supported variable from "everything-except-SPI" to "nothing". All programmers have to set the bus type on their own, and this enables register_spi_programmer to just add the SPI both for on-board SPI interfaces (where the internal programmer already detected the other bus types), as well as for external programmers (where we have the default "none").

| | | | | | | | | | | | | | | | | | | | | | | | | | | Flashrom currently only supports exactly one Super I/O or Embedded Controller, and this means quite a few notebooks and a small subset of desktop/server boards cannot be handled reliably and easily. Allow detection and initialization of up to 3 Super I/O and/or EC chips. WARNING! If a Super I/O or EC responds on multiple ports (0x2e and 0x4e), the code will do the wrong thing (namely, initialize the hardware twice). I have no idea if we should handle such situations, and whether we should ignore the second chip with identical ID or not. Initializing the hardware twice for the IT87* family is _not_ a problem, but I don't know how well IT85* can handle it (and whether IT85* would listen at more than one port anyway).

* Add support for the Open Graphics Project development card, OGD1, as a SPI ↵Mark Marshall2010-12-031-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flash programmer The project is in the the process of designing and making a complete, open source, graphics card. More info at http://wiki.opengraphics.org. The first development card is a PCI add in card containing a couple of FPGAs and a couple of serial flash chips (amongst other things). The FPGAs are called XP10 and S3 (their part numbers). The XP10 contains its own flash and does not need to be programmed by flashrom - it ensures that the device can enumerate on the PCI bus without needing further configuration. The larger FPGA is the S3. This is configured from a large SPI flash (2 MBytes). The second SPI flash is used to store the VGA BIOS. It is smaller (128 KBytes). This patch adds support for programming either of the two SPI flash chips. The programmer device takes one configuration option which selects which of the two flash chips is accessed. This must be set to either "cprom" or "bprom". (The project refers to the two chips as "cprom" / "bprom", "s3" and "bios" are more readable alternatives). Add support for SST SST25VF010 (REMS).

* Fix two memory leaks in doit() and refine get_next_write()Carl-Daniel Hailfinger2010-11-051-81/+63
| | | | | | | | | | | | | | | | | Avoid two memory leaks in doit() which were unproblematic for flashrom because flashrom terminates after finishing doit(). Rename oldcontents to curconents in erase_and_write_block_helper(). Unify the code for all granularities in get_next_write(). Return write length from get_next_write() instead of filling it as referenced parameter. Thanks to Michael Karcher for pointing out the first two issues. Thanks to David Hendricks for pointing out the third issue and suggesting a way to unify that code. Corresponding to flashrom svn r1225.

* This patch makes flashrom use real partial writesCarl-Daniel Hailfinger2010-11-041-40/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you write an image full of 0xff, flashrom will erase and detect that no write is needed. If you write an image which differs only in some parts from the current flash contents, flashrom will detect that and not touch unchanged areas. Fix a long-standing bug in need_erase() for 256 byte granularity as well. Nice side benefit: Detailed progress printing. S means skipped E means erased W means written Thanks to Andrew Morgan for testing countless iterations of this patch. Thanks to Richard A. Smith for testing on Dediprog SF100. Thanks to David Hendricks for the review and for creating a partial write torture test script and testing with it on Intel NM10 and AMD SB700 SPI. Thanks to Idwer Vollering for testing with Intel SPI NICs. Thanks to Rudolf Marek for testing on AMD SB710 and SiI SATA controllers. Thanks to Michael Karcher for the review.

* Always read the flash chip before writingCarl-Daniel Hailfinger2010-10-191-11/+66
| | | | | | | | | | | | | | | | | | | | | This will allow flashrom to skip erase of already-erased blocks and to skip write of blocks which already have the wanted contents. Avoid emergency messages by checking if the chip contents after a failed write operation (erase/write) are unchanged. Keep the emergency messages after a failed pure erase. That part is debatable because if someone wants erase, he pretty sure doesn't care about the flash contents anymore. Please note that this introduces additional overhead of a full chip read before write. This is frowned upon by people with slow programmers. A followup patch will make this configurable.

* Refactor doit()Carl-Daniel Hailfinger2010-10-151-81/+100
| | | | | | | | | | | | | | Doit() is the monster function we split off from main() when we created cli_classic() and tried to introduce some abstraction. doit() is a poster child of WTFs on an astronomic scale. Make doit() less bad by factoring out self-contained code. Corresponding to flashrom svn r1212.

* Move implicit erase out of chip driversCarl-Daniel Hailfinger2010-10-081-9/+17
| | | | | | | | | | | | | | | | | | Flashrom had an implicit erase-on-write for most flash chip and programmer drivers, but it was not entirely consistent. Some drivers had their own hand-rolled partial update functionality which made handling partial updates from generic code impossible. Move implicit erase out of chip drivers, and kill some dead erase functions at the same time. A full chip erase is now performed in the generic code for all flash chips on write, and after that the whole chip is written. Corresponding to flashrom svn r1206.
