* linux_spi.c: Refactor singleton states into reentrant patternAnastasia Klimchuk2021-04-181-12/+33
| | | | | | | | | | | | | | | | | | Move global singleton states into a struct and store within the spi_master data field for the life-time of the driver. This is one of the steps on the way to move spi_master data memory management behind the initialisation API, for more context see other patches under the same topic "register_master_api".

* linux_spi.c: Separate shutdown from failed init cleanupAnastasia Klimchuk2021-04-181-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | Shutdown function was covering two different jobs here: 1) the actual shutdown which is run at the end of the driver's lifecycle and 2) cleanup in cases when initialisation failed. Now, shutdown is only doing its main job (#1), and the driver itself is doing cleanup when init fails (#2). The good thing is that now resources are released/closed immediately in cases when init fails (vs shutdown function which was run at some point later), and the driver leaves clean space after itself if init fails. And very importantly this unlocks API change which plans to move register_shutdown inside register master API, see this https://review.coreboot.org/c/flashrom/+/51761 TEST=builds BUG=b:140394053 Change-Id: I1c8da2878cd0e85a1e43ba9b4b8e6f3d9f38ae5c Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/52284 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org>

| | | | | | | | | | | | | | | | | To get max_kernel_buf_size is a piece of logic on its own, it opens resources and closes resources, also has some local variables only for this task. Extracting get_max_kernel_buf_size() as a separate function simplifies init flow and allows to remove global state from linux_spi (see next patches in this chain).

* linux_spi: Use fgets() to read buffer sizeJacob Garber2019-09-241-2/+1
| | | | | | | | | | | | | | | Since fread() returns the number of bytes read, this currently will only check for errors if it returns 0 (i.e. the file was empty). However, it is possible for fread() to encounter an error after reading a few bytes, which this doesn't catch. Fix this by using fgets() instead, which will return NULL if EOF or an error is encountered, and is simpler anyway.

It seems to be quite likely that all AT25F512 are fully functional relabeled AT25F1024 chips. There are even some hints in the datasheet: in table 6 they stress that address pin 16 needs to be low under all circum- stances; while continuous reads can wrap around on the AT25F1024 the DS notes "For the AT25F512, the read command must be terminated when the highest address (00FFFF) is reached."

Refine the comment explaining the scheme on top of the list. - Support -L output of chip sizes with up to 6 decimal places (up to 4 Gb). - Use z length modifier in (more) prints for size_t types. - Remove chips >16MB again because our current implementation of memory mapping the flash chip violates common rules by mapping a window as large as the chip. This leads to failing mmaps as can be seen here: http://paste.flashrom.org/view.php?id=1695 - Document spispeed parameter of linux_spi (and fix some leaks). - Rephrase the "multiple chips detected" message because it was confusing. - Skip verification step if the image is equal to the flash contents. - Tiny other stuff.

* Let the programmer driver decide how to do AAI transfersNico Huber2012-06-151-0/+1
| | | | | | | | | | | | | | | | Currently spi_aai_write() is implemented without an abstraction mechanism for the programmer driver. This adds another function pointer 'write_aai' to struct spi_programmer, which is set to default_spi_write_aai (renamed spi_aai_write) for all programmers for now. A patch which utilises this abstraction in the dediprog driver will follow. Corresponding to flashrom svn r1543.

* Prevent submission of empty read requests in linux_spiMichael Karcher2012-03-061-2/+14
| | | | | | | | | | | | | | The submission of zero-sized read requests in a write-only transaction fails at least for omap2_mcspi drivers and is pointless in general. This patch does not address the implementation of zero-sized writes (which would need to skip the write command), as there are no flash transactions not starting with a command.

| | | | | | | | | | | | | | | | 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.
