2019-12-25mainboard/google/hatch: Move gpio GPP_H3 config up from baseboardEdward O'Callaghan
The baseboard GPIO table definitions are too straineous to the extend that variants need to redefine assumptions back to NC. Invert this so that baseboard by default assumes the safer NC and move the specific board configurations to their respective places. This patch handles the GPP_H3 gpio config for easier review. This toggles the MAX amp which not all boards have. Move the pin configuration to boards with the respective devicetree configuration following on from the theme of commit b417786525.

2019-12-05hatch: Fix FPMCU pwr/rst gpio handlingCraig Hesling
1. No gpio control in bootblock 2. Disable power and assert reset in ramstage gpio 3. Power on and then deassert reset at the end of ramstage gpio 4. Disable power and assert reset when entering S5 On "reboot", the amount of time the power is disabled for is equivalent to the amount of time between triggering #4 and wrapping around to #3, which is about 400ms on Kohaku. Since #2 forces power off for FPMCU, S3 resume will still not work properly. Additionally, we must ensure that GPP_A12 is reconfigured as an output before going to any sleep state, since user space could have configured it to use its native3 function. See https://review.coreboot.org/c/coreboot/+/32111 for more detail. The control signals have been validated on a Kohaku in the following scenarios: 1. Cold startup 2. Issuing a "reboot" command 3. Issuing a "halt -p" and powering back on within 10 seconds 4. Issuing a "halt -p" and powering back on after 10 seconds 5. Entering and leaving S3 (does not work properly) 6. Entering and leaving S0iX BRANCH=hatch BUG=b/142751685 TEST=Verify all signals as mentioned above TEST=reboot flash_fp_mcu /opt/google/biod/fw/dartmonkey_v2.0.2417-af88cc91a.bin TEST=halt -p # power back on within 10 seconds flash_fp_mcu /opt/google/biod/fw/dartmonkey_v2.0.2417-af88cc91a.bin TEST=halt -p # power back on after 10 seconds flash_fp_mcu /opt/google/biod/fw/dartmonkey_v2.0.2417-af88cc91a.bin Change-Id: I2e3ff42715611d519677a4256bdd172ec98687f9 Signed-off-by: Craig Hesling <hesling@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/37459 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

2019-08-09mb/google/hatch: Refactor override_early_gpio_tableTim Wawrzynczak
There was the potential for misuse of the override early GPIO table, because if the override early GPIO table did not have a corresponding entry in the base table, it would not get overridden, and there was no way to know except manual inspection (this has already happened here), so now all hatch mainboards are required to explicitly list out all of their required early GPIOs.
