      [POWERPC] Fix problems with device tree representation of TSI-1xx bridges · e58ca3de
      由 David Gibson 提交于 
      This fixes some problems with the way the some things
represented in the device tree for the Holly and Taiga boards.  This
means changes both to the dts files, and to the code which
instantiates the tsi108 ethernet platform devices based on the device
tree.

	- First, and most importantly, the ethernet PHYs are given
with an identical 'reg' property.  This reg currently encodes the
accessible register used to initiate mdio interaction with the PHYs,
rather than a meaningful address on the parent bus (mdio in this
case), which is incorrect.  Instead we give the address of these
registers as 'reg' in the mdio node itself, and encode the ID of each
phy in their 'reg' propertyies.
	- Currently the platform device constructor enables a
workaround in the tsi108 ethernet driver based on the compatible
property of the PHY.  This is incorrect, because the workaround in
question is necessary due to the board's wiring of the PHY, not the
model of PHY itself.  This patch alters the constructor to instead
enable the workaround based on a new special property in the PHY node.
	- The compatible properties on a number of nodes in the device
tree are insufficiently precise.  In particular the PHYs give only
"bcm54xx", which is broken, since there are many bcm54xx PHY models,
and they have differences which matter.  The mdio had a compatible
property of "tsi-ethernet" identical to the ethernet MAC nodes, which
doesn't make sense.  The ethernet, i2c, bridge and PCI nodes were
given only as "tsi-*" which is somewhat inprecise, we replace with
"tsi108-*" in the case of Taiga (which has a TSI108 bridge), and
"tsi109-*", "tsi108-*" in the case of Holly (which has a TSI109
bridge).
	- We remove some "model" properties from the ethernets on
Taiga board which were neither useful nor adequately precise.
	- On Holly we change to using a dtc label instead of a full
path to reference the MPIC node, which makes the dts a little more
readable.

      [POWERPC] Don't store a command line in the Holly device tree · e60c526f
      由 David Gibson 提交于 
      Currently, the Holly device tree includes a bootargs property in
/chosen, which gives a commandline.  This is somewhat inconvenient,
because it means an alternative default command line can't be given in
the kernel config - the value obtained from the dts via the
bootwrapper will always override CONFIG_CMDLINE.

This removes the command line from the dts, and instead puts the
same command line as a default in holly_defconfig.

      [POWERPC] Consolidate cuboot initialization code · 85aecac8
      由 David Gibson 提交于 
      The various cuboot platforms (i.e. pre-device tree aware u-boot for
83xx, 85xx and Ebony) share a certain amount of code for parsing the
boot parameters.  To a certain extent that's inevitable, since they
platforms have different definitions of the bd_t structure.  However,
with some macro work and a helper function, this patch improves the
situation a bit.

In the process, this fixes a bug on Ebony, which was incorrectly
handling the parameters passed form u-boot for the command line (the
bug was copied from 83xx and 85xx which have subsequently been fixed).

      [POWERPC] Derive ebc ranges property from EBC registers · b2ba34f3
      由 David Gibson 提交于 
      In the device tree for Ebony, the 'ranges' property in the node for
the EBC bridge shows the mappings from the chip select / address lines
actually used for the EBC peripherals into the address space of the
OPB.  At present, these mappings are hardcoded in ebony.dts for the
mappings set up by the OpenBIOS firmware when it configures the EBC
bridge.

This replaces the hardcoded mappings with code in the zImage to
read the EBC configuration registers and create an appropriate ranges
property based on them.  This should make the zImage and kernel more
robust to changes in firmware configuration.  In particular, some of
the Ebony's DIP switches can change the effective address of the Flash
and other peripherals in OPB space.  With this patch, the kernel will
be able to cope with at least some of the possible variations.

      [POWERPC] Factor zImage's 44x reset code out of ebony.c · 11123346
      由 David Gibson 提交于 
      The ebony_exit() function which resets the Ebony board should in fact
be common to most if not all 44x boards.  This moves the function out
into 44x.c, renaming it, so it can be used by other 44x platforms.

      [POWERPC] Split low-level OF-related bootloader code into separate files · 2e601613
      由 David Gibson 提交于 
      Currently, all OF-related code in the bootloader is contained in of.c.
of.c also provides the platform specific things necessary to boot on
an OF platform.

However, there are platforms (such as PReP) which can include an OF
implementation, but are not bootable as pure OF systems.  For use by
such platforms, this patch splits out the low-level parts of the OF
code (call_prom() and various wrappers thereof) into a new oflib.c
file.  In addition, the code related to bootwrapper console output via
OF are moved to a new ofconsole.c file.  Both these files are included
in the wrapper.a library where they can be used by both full-OF and
partial OF platforms.

      [POWERPC] Fix building of COFF zImages · f40e524e
      由 Paul Mackerras 提交于 
      The COFF zImage (for booting oldworld powermacs) wasn't being built
correctly because the procedure descriptor in crt0.S for the zImage
entry point wasn't declared as .globl, and therefore wasn't getting
pulled in from wrapper.a by the linker.  This adds the necessary
.globl statement.
