2019-06-21mediatek: Add SPI tick_dly settingMengqi Zhang
Add spi tick_dly setting for high-speed spi xfer. BUG=b:80501386 BRANCH=none TEST=emerge-kukui coreboot; emerge-elm coreboot Change-Id: Ie49fc3efe2a4a6dcdf2a2fc4c91b47e35d4f086e Signed-off-by: Mengqi Zhang <Mengqi.Zhang@mediatek.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32461 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
2019-04-09google/kukui: Configure AP_IN_SLEEP_L correctlyYou-Cheng Syu
This pin should be set to its alternative function SRCLKENA0 instead of GPIO, so that SPM (a power management component of MT8183) can control it. BUG=b:113367227 BRANCH=none TEST=1. Boot. Run 'powerinfo' in EC console and see power state in S0. 2. Run 'powerd_dbus_suspend --wakeup_timeout=10', and then run 'powerinfo' in EC console and see power state in S3. 3. Wait until AP resume. 4. Run 'powerinfo' in EC console and see power state back to S0.

2019-01-29google/kukui: Move some initialization from bootblock to verstageYou-Cheng Syu
MT8183 only allows booting from eMMC, so we have to do eMMC emulation from an external source, for example EC, which makes the size of bootblock very important. This CL moves some initialization steps from bootblock to verstage. This will save us about 2700 bytes (before compression) / 1024 bytes (after LZ4 compression) in bootblock. In case of CONFIG_VBOOT is disabled, these initialization steps will be done in romstage.
