The mv64x60 host bridge has many windows between its various components (cpu, system memory, ethernet ctlr, MPSC, DMA ctlr, PCI MEM, PCI I/O). Unfortunately, the firmware on some of mv64x60-based platforms do not properly or completely configure those windows (e.g., MPSC->system memory windows not configured or CPU->PCI MEM space not configured). So, the missing configuration needs to be done in either the bootwrapper or in the kernel. To keep the kernel as clean as possible, it is done in the bootwrapper. Note that I/O controller configuration is NOT being done, its only the windows to allow the I/O controllers and other components to access memory, etc. that is being done--drivers assume that their controllers can already access system memory). Table of routines and the windows they configure: mv64x60_config_ctlr_windows() ENET->System Memory MPSC->System Memory IDMA->System Memory mv64x60_config_pci_windows() PCI MEM->System Memory PCI I/O->Bridge's Registers mv64x60_config_cpu2pci_window() CPU->PCI MEM CPU->PCI I/O Signed-off-by: Mark A.

# Makefile for making ELF bootable images for booting on CHRP
|
|
# using Open Firmware.
|
|
#
|
|
# Geert Uytterhoeven September 1997
|
|
#
|
|
# Based on coffboot by Paul Mackerras
|
|
# Simplified for ppc64 by Todd Inglett
|
|
#
|
|
# NOTE: this code is built for 32 bit in ELF32 format even though
|
|
# it packages a 64 bit kernel. We do this to simplify the
|
|
# bootloader and increase compatibility with OpenFirmware.
|
|
#
|
|
# To this end we need to define BOOTCC, etc, as the tools
|
|
# needed to build the 32 bit image. These are normally HOSTCC,
|
|
# but may be a third compiler if, for example, you are cross
|
|
# compiling from an intel box. Once the 64bit ppc gcc is
|
|
# stable it will probably simply be a compiler switch to
|
|
# compile for 32bit mode.
|
|
# To make it easier to setup a cross compiler,
|
|
# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
|
|
# in the toplevel makefile.
