From 25c0330aa6bba60e36ac460d12ef954332852426 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Fri, 8 Mar 2013 09:20:32 +0000 Subject: [PATCH] ACPICA: iASL/Disassembler: Add support for VRTC table VRTC is used in Intel MID platforms as a replacement of the traditional x86 RTC. VRTC table can be found in the recent ACPI BIOS enabled Intel MID platforms. The format of this table has been defined in the "Simple Firmware Interface Specification" except it uses GAS instead of 64-bit values for address fields. This patch introduces VRTC table support into ACPICA. Lv Zheng. Signed-off-by: Lv Zheng Signed-off-by: Bob Moore Signed-off-by: Rafael J.
