From 6577ec4de4290d3adbf5fbdc31b09b38c09100cf Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Sat, 3 Oct 2020 23:07:36 +0530 Subject: soc/intel/common/block/acpi: Factor out common platform.asl This patch moves platform.asl into common block acpi directory to avoid duplicating the same ASL code block across SoC directory. TEST=Able to build and boot TGL, CNL and CML platform. 1) Dump and disassemble DSDT, verify _PIC method present inside common platform.asl is still there. 2) Verify no ACPI error seen while running 'dmesg` from console.
