* programmer: Smoothen register_spi_master() APINico Huber2021-05-131-1/+1
| | | | | | | | | | | | | 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.

* jlink_spi.c: Drop jaylink_ prefix for spi data struct membersAnastasia Klimchuk2021-04-271-31/+31
| | | | | | | | | | | | | | | | | | Since jaylink context and jaylink device handle are not global variables anymore, but members of the struct jlink_spi_data, jaylink_ prefix can be dropped from members names and moved to struct variable name. Follow up on 52560.

* jlink_spi.c: Refactor singleton states into reentrant patternAnastasia Klimchuk2021-04-221-20/+47
| | | | | | | | | | | | | | | | | | | | 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".

* jlink_spi.c: Separate shutdown from failed init cleanupAnastasia Klimchuk2021-04-161-18/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | 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:185191942 Change-Id: I71f64ed38154af670d4d28b8c7914d87fbc75679 Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/52308 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>

* 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.
