From 7f2ab000c6f2ae46070807a3bf645c45d8639460 Mon Sep 17 00:00:00 2001 From: Rajiv Andrade Date: Thu, 13 May 2010 17:37:54 -0300 Subject: TPM: ACPI/PNP dependency removal This patch pushes the ACPI dependency into the device driver code itself. Now, even without ACPI/PNP enabled, the device can be registered using the TIS specified memory space. This will however result in the lack of access to the BIOS event log, being the only implication of such ACPI removal.
