Subject: [PATCH 1/2] qe_lib: qe_issue_cmd writes wrong value to CECDR
Date: Tue, 31 Oct 2006 17:53:42 +0800 [thread overview]
Message-ID: <45471D26.1050000@freescale.com> (raw)
From: Timur Tabi <timur@freescale•com>
Changed qe_issue_cmd() to write cmd_input to the CECDR unmodified. It
was treating cmd_input as a virtual address and tried to convert it to
a physical address.
