From d72c39114c3f36785bb71aaf9dea642e59723abc Mon Sep 17 00:00:00 2001 From: "Hon Ching \\(Vicky\\) Lo" Date: Wed, 17 Jun 2015 18:17:09 -0400 Subject: TPM: remove unnecessary little endian conversion The base pointer for the event log is allocated in the local kernel (in prom_instantiate_sml()), therefore it is already in the host's endian byte order and requires no conversion. The content of the 'basep' pointer in read_log() stores the base address of the log. This patch ensures that it is correctly implemented.
