From e4cb23c68225d2973f771d61b5dc7725a1c92c2f Mon Sep 17 00:00:00 2001 From: Mario Scheithauer Date: Thu, 7 Mar 2019 09:48:33 +0100 Subject: src/soc/intel/apollolake/cpu.c: Set up local APIC Some Apollo Lake mainboards use SeaBIOS as payload. SeaBIOS requires the initialization of the programmable interrupt controller (PIC) for faultless operation. The PIC mode is need for USB support (e.g. keyboard, memory stick) and for some Option ROMs (e.g. PXE ROM). Therefore add setup_lapic() to configure the APIC.
