* lspcon_i2c_spi: support a devpath optionPeter Marheine2021-05-023-52/+80
| | | | | | | | | | | | | | | | | | | | | | Some callers may find it easier to provide the path to an I2C device at which to communicate with the device, rather than specify the bus number- doing so might involve trying to parse a path to extract the number only for flashrom to do the reverse, which is error-prone and unnecessary. This change adds support for a `devpath` option, continuing to allow `bus` and requiring only one of them be specified. TEST=Verified --flash-size outputs correct values with both devpath=/dev/i2c-7 and bus=7, as well as noting that one is required if neither is specified and only one may be specified if both are given.

* mec1308.c: Separate shutdown from failed init cleanupAnastasia Klimchuk2021-04-271-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 TEST=builds and ninja test from 51487 BUG=b:185191942 Change-Id: I6d62d43dd8b6ebc595f9fd747e0f4cd80f3c10da Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/52597 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>

All later anita runs use an arch-dependent default (32M for i386, so this might explain why it was never stable). Assuming most machines have >1GiB RAM per processor core available, we can also increase the runtime size further (better to waste some RAM than to wait very long because it starts swapping things out). We choose 512MiB for 64-bit targets and 256MiB for 32-bit ones. However, we don't need that much for the initial installation step and it also decides the size of the swap partition. So we use a smaller size initially that's just enough to get us through the installation quickly enough (192MiB & 128MiB).

* ene_lpc.c: Move register_shutdown to the end of initialisationAnastasia Klimchuk2021-04-181-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | A bit more details: since register_shutdown has moved a few lines below, now ene_enter_flash_mode is called before the shutdown function is registered. ene_enter_flash_mode can fail (at least in theory, it has some return 1s), but its return value is not analyzed, so even if it returns non-0, execution goes further and register_shutdown will happen anyway. It is a separate question whether the return value of ene_enter_flash_mode needs to be analyzed or is it ok to ignore it, but in this patch I plan to keep the same behaviour, and probably I will get back to error handling later. This unlocks API change which plans to move register_shutdown inside register master API, see https://review.coreboot.org/c/flashrom/+/51761 TEST=builds BUG=b:185191942 Change-Id: If89a758c91c77486adbac2779449bcd71ab8fc78 Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/52406 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Nico Huber <nico.h@gmx.de>
