* spi_master: Use new API to register shutdown functionAnastasia Klimchuk2021-08-251-11/+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. BUG=b:185191942 TEST= 1) builds and ninja test including CB:56911 2) On ARMv7 device flashrom -p linux_spi -V -> using linux_spi, chip found 3) On x86_64 AMD device flashrom -p internal -V -> this is actually using sb600spi, chip found Change-Id: Ib60300f9ddb295a255d5ef3f8da0e07064207140 Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/56103 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org>

* stlinkv3_spi.c: Refactor singleton states into reentrant patternAnastasia Klimchuk2021-05-221-29/+66
| | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | It was impossible to register a const struct spi_master that would point to dynamically allocated `data`. Fix that so that we won't have to create more mutable globals.

* const'ify flashctx to align signatures with cros flashromEdward O'Callaghan2020-04-301-1/+1
| | | | | | | | | | | | | | | | The ChromiumOS flashrom fork has since const'ify flashctx in a few places. This aligns the function signatures to match with downstream to ease forward porting patches out of downstream back into mainline flashrom. This patch is minimum viable alignment and so feedback is welcome.
