Hello Dinesh Gehlot, Dtrain Hsu, Eric Lai, Jayvik Desai, Kapil Porwal, Nick Vaccaro, Subrata Banik, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/86514?usp=email
to look at the new patch set (#8).
Change subject: mb/trulo/var/uldrenite: Fix boot time caused by WWAN initialization ......................................................................
mb/trulo/var/uldrenite: Fix boot time caused by WWAN initialization
The previous approach would increase the delay time by 50 ms. So move WWAN power sequence to GPIO control to reduce boot time caused by WWAN initialization. Additionally, add a 150ms delay to T0_OFF_MS before powering off the WWAN. This ensures that the WWAN Power OFF Sequence operates correctly during a reboot.
BUG=b:383212261 BRANCH=firmware-trulo-15217.771.B TEST=Confirm the measured WWAN power sequence
