From b8ec2385038c094b07ec5b49336289a46b6e9cc6 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Mon, 7 Jan 2008 13:31:19 -0600 Subject: 85xx: 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. Add command-line command "qe fw" to take a firmware blob in memory and upload it. Update ft_cpu_setup() on 85xx to create the 'firmware' device tree node if U-Boot has uploaded a firmware. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers.
