Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/44293 ) Change subject: [UNTESTED]drivers/amd/agesa/s3_mtrr.c: Use a struct over pointer aritmetic ...................................................................... [UNTESTED]drivers/amd/agesa/s3_mtrr.c: Use a struct over pointer aritmetic The size of the data used is fixed in this function so there is no need for this aritmetic. The function signature will be changed in a followup commit.

Stefan Ott has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/40678 ) Change subject: mb/lenovo/t60: Add support for ThinkLight ...................................................................... mb/lenovo/t60: Add support for ThinkLight With this patch, the ThinkLight on the ThinkPad T60 can be controlled through the OS. This was initially done for the X201 in f63fbdb6: mb/lenovo/x201: Add support for ThinkLight. After applying this patch, the light can be controlled like this: echo on >/proc/acpi/ibm/light echo off >/proc/acpi/ibm/light Or through sysfs at /sys/class/leds/tpacpi::thinklight Unfortunately I do not own a T60 to test this.
