* meson: revert to meson version 0.53.0Thomas Heijligen2023-03-033-6/+3
| | | | | | | | | | | | | | | | Debian Bullseye, current stable release, ships only with meson 0.56.2. To go back to an older meson version pass the project_version info as parameter to `sphinx-build` instead of using an environment variable. This is done by overriding the `release` variable in conf.py with `-Drelease=meson.project_version()` at the command line call.

* spi: Make default cmd helpers static internalEdward O'Callaghan2023-03-032-23/+19
| | | | | | | | | | | | | | | | | | | | Avoid these leaking into driver implementations as a NULL field now implies their implementation. This removes one source of a driver bug where both `mst->command` AND `mst->multicommand` are set to default implementations which is actually a cyclical control flow condition. The driver however must still have either `mst->command` OR `mst->multicommand` defined and so both cannot be NULL. This simplifies the code and driver development.

* writeprotect: Add function to get register values and WP bit masksNikolai Artemiev2023-03-035-0/+101
| | | | | | | | | | | | | | | | | | | | | | | Add a new wp_cfg_to_reg_values() function that takes a generic wp_cfg instance and returns the chip-specific values that need to be written to the chip's registers to enable the specified protection range/mode. The function returns three values for each chip register: - reg_values[reg] - Value writeprotect will write to reg - bit_masks[reg] - Bit mask for WP-related bits in reg - write_masks[reg] - Bit mask for writable WP-related bits in reg (i.e. the ones writeprotect will try to write) BUG=b:260019525,b:259013033,260020006 BRANCH=none TEST=ninja test Change-Id: Ib2a47153b230c9f82bb4eca357c335f2abbacc20 Signed-off-by: Nikolai Artemiev <nartemiev@google.com> Reviewed-on: https://review.coreboot.org/c/flashrom/+/69847 Reviewed-by: Edward O'Callaghan <quasisec@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Sergii Dmytruk <sergii.dmytruk@3mdeb.com>

* move manpage to sphinxThomas Heijligen2023-03-019-1870/+1468
| | | | | | | | | | | | | | | | | | | | | | | | | Use sphinx (sphinx-doc.org) to generate the UNIX man page from an reStructuredText file instead of dealing with plain groff. Use `meson setup -Dman-pages=enabled` to build the man page, and `meson setup -Ddocumentation=enabled` to build the web documentation explicitly. Both are enabled automatically if sphinx-build is found. The man page will be installed as `<meson_mandir>/man8/flashrom.8` and The html documentation in <meson_datadir>/doc/flashrom/html`. The Makefile builds only the man-page format. Increase the minimum version of meson from 0.53.0 to 0.57.0 to be able to pass environment variables to the custom_target() command. That is needed to pass the FLASHROM_VERSION to the documentation.

| | | | | | | | | | | | | | | | | | | | | | | Add support for the WCH CH347, a high-speed USB to bus converter supporting multiple protocols interfaces including SPI. Currently only mode 1 (vendor defined communication interface) is supported, mode 2 (USB HID communication interface) support will be added later. The code is currently hard coded to use CS1 and a SPI clock of 15 MHz, though there are 2 CS lines and 6 other GPIO lines available, as well as a configurable clock divisor for up to 60MHz operation. Support for these will be exposed through programmer parameters in later commits. This currently uses the synchronous libusb API. Performance seems to be alright so far, if it becomes an issue I may switch to the asynchronous API.

To avoid unexpected memory freeing by shutdown function, we need to keep track of how many buses are using the shared resource. Use the reference counting technique to achieve this.

| | | | | | | | | | | | | | | | | Note that while I can read the chip, on my Lenovo Legion T5 28IMB05, cannot write to the flash chip with any tools except upgrading with vendor tool, no downgrades are allowed, due to the fact of SMM, even if I did manage to flash the BIOS chip somehow, would still face bootguard since this machine has bootguard. But if I read the chip, and verify my read bin file, it works fine, until changing the SMBIOS, which is in the vendor BIOS update package.

| | | | | | | | | | | | | | | | | | | | | | | | | | 1) Add function to flatten out the addresses of the flash chip as per the different erase functions. This function will return a list of layouts which is dynamically allocated. So after use all the layouts as well as the list itself should be freed. The free_erase_layout function does that. 2) Add function to align start and end address of the region (in struct walk_info) to some erase sector boundaries and modify the region start and end addresses to match nearest erase sector boundaries. This function will be used in the new algorithm for erase function selection. 3) Add function that returns a list of sectors (as seen by the first erase function) that need erasing. 4) Add a function to call the erase algorithm.
