* spi_master: Use new API to register shutdown functionAnastasia Klimchuk2021-08-251-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows spi masters to register shutdown function in spi_master struct, which means there is no need to call register_shutdown in init function, since this call is now a part of register_spi_master. As a consequence of using new API, two things are happening here: 1) No resource leakage anymore in case register_shutdown() would fail, 2) Fixed propagation of register_spi_master() return values. Basic testing: when I comment out free(data) in linux_spi_shutdown, test fails with error ../linux_spi.c:235: note: block 0x55a4db276510 allocated here ERROR: linux_spi_init_and_shutdown_test_success leaked 1 block(s) Means, shutdown function is invoked.

* buspirate_spi.c: Separate shutdown from failed init cleanupAnastasia Klimchuk2021-06-201-49/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 https://review.coreboot.org/c/flashrom/+/51761 BUG=b:185191942 TEST=builds Change-Id: I04d57e2552d23a1a4a906c68539f0ccefc13e8a0 Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/52877 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org> Reviewed-by: Nico Huber <nico.h@gmx.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

* buspirate_spi: Add support for variable serial speedsShawn Anastasio2018-01-261-11/+121
| | | | | | | | | | | | | | | | | | | | | | | | This patch sets the default baud rate for communication between the host device and the Bus Pirate for hardware versions 3.0 and greater to 2M baud. It also introduces the ability to manually set the baud rate via the added 'serialspeed' programmer parameter. This is done in two parts. Firstly, the requested serial speed is looked up in a table to determine the appropriate clock divisor and the divisor is sent to the bus pirate. Then, the system's baud rate for the selected serial port is set using serial.c's 'serialport_config'. This function's prototype had to be added to programmer.h. In testing, using the 2M baud rate was able to significantly decrease flash times (down from 20+ minutes to less than 2 minutes for an 8MB flash).

| | | | | | | | | | | | | | | | | | | | | | | | | The Bus Pirate firmware (at least v6.1 and earlier) can't handle UART input buffer overflow in BBIO mode, and sending a sequence of 0x00 too fast apparently triggers such an UART input buffer overflow. Wait 10 ms after sending each 0x00 byte during init to give the Bus Pirate enough time to handle the input. This fixes a Bus Pirate hang if the previous flashrom run was aborted by the user. The Bus Pirate firmware v6.1 and earlier use the wrong (too slow) SPI speed if more than 2 MHz are requested. Automatically downgrade SPI speed to 2 MHz for affected firmware versions. Detect Bus Pirate hardware and firmware versions to allow quirk handling. The Bus Pirate init sequence has lots of open-coded sequences which wait for a given string on the serial line.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-35/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Fix compilation for CONFIG_INTERNAL=noCarl-Daniel Hailfinger2011-06-091-0/+5
| | | | | | | | | | | | CONFIG_INTERNAL implies Super I/O support and NEED_PCI. NEED_PCI is only used to guard PCI stuff which may be needed for external PCI-based programmers. That way, using #if NEED_PCI can be avoided inside #if CONFIG_INTERNAL. Corresponding to flashrom svn r1326.

* Kill central list of SPI programmersMichael Karcher2011-05-111-3/+15
| | | | | | | | | | | | | | | | | | 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").

* Handle Bus Pirates already in bit banging mode correctlyCarl-Daniel Hailfinger2010-09-161-0/+21
| | | | | | | | | | | | | | | | | | | | Thanks to Johannes Sjölund for reporting that the Bus Pirate init could 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. Corresponding to flashrom svn r1178.

* Speed up Bus Pirate by exploiting the FTDI FIFOCarl-Daniel Hailfinger2010-07-291-20/+22
| | | | | | | | | | | | | | | | | If we violate the raw SPI communication protocol requirements of the Bus 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.

| | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | from programmer_param 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. Use extract_param everywhere, clean up related code and make it more foolproof. Add two instances of exit(1) where we have no option to return an error. Remove six instances of exit(1) where returning an error was possible. WARNING: This changes programmer parameter syntax for a few programmers! Corresponding to flashrom svn r1070.
