* minute-ia: hard reset if we panic while handling a panicJack Rosenthal2019-04-251-13/+9
| | | | | | | | | | | | | | | | | | | | | ish_pm_reset is a rather complex procedure, and encountering a panic while it is happening could lead to an infinte loop of handling panics. This will preform a reset of the Minute-IA core if a panic occurs and the system is already resetting from panic. BUG=b:130752748,b:130587334 BRANCH=none TEST=copied some invalid opcodes into switch_to_aontask procedure, observed the hard reset after forcing a panic Change-Id: I43459d78da9b67297f84e3a736d3f92da42a814c Signed-off-by: Jack Rosenthal <jrosenth@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/1576835 Reviewed-by: Jett Rink <jettrink@chromium.org> (cherry picked from commit 2ece52589486990cca666dc3ebc4164d5f2c0aed) Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/1584767 Commit-Queue: Jett Rink <jettrink@chromium.org> Tested-by: Jett Rink <jettrink@chromium.org>

* system: Allow hibernate to clear AP_OFF flagDaisuke Nojiri2017-12-051-0/+5
| | | | | | | | | | | | | | | | | | | After firmware update, cr50 toggles the EC's reset line, expecting the system will boot. This isn't the case for Chromebox because it sets AP_OFF flag on a clean shutdown (to restore the previous power state after power loss & restore). This patch adds EC_REBOOT_HIBERNATE_CLEAR_AP_OFF to EC reboot command. It makes EC first clear AP_OFF then hibernate. BUG=b:69721737 BRANCH=none TEST=Verify Fizz reboot after cr50 update.

* ish: Add support for ISH chipJaiber John2016-11-041-0/+120
This patch adds the initial support for ISH chip to enable the EC firmware to boot on Intel Integrated Sensor Hub (ISH). The following are enabled: 1. Inter-Processor Communication (IPC) driver that enables the ISH to communicate with the host Operating system via shared registers. 2. High Precision Event Timer (HPET) driver that provides configurable timers for the FW to use in task scheduling. 3. I2C bus driver for accessing sensors. 4. UART console driver with TX support only.
