From bc556ba940085e46e0ab1b5ed7c31428dc86dd03 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 8 Jan 2008 10:30:58 -0600 Subject: [POWERPC] QE: Add ability to upload QE firmware Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers. Added description of a new QE firmware node to booting-without-of.txt.
