The interrupt routing in the device trees for the ULI M1575 was
inproperly using the interrupt line field as pci function. Fixed
up the device tree's to actual conform for to specification and
changed the interrupt mapping code so it just uses a static mapping
setup as follows:
PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9
USB 1.1 OCHI (1c.2) - IRQ10
USB 1.1 ECHI (1c.3) - IRQ11
LAN (1b.0) - IRQ6
AC97 (1d.0) - IRQ6
Modem (1d.1) - IRQ6
HD Audio (1d.2) - IRQ6
SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15
Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.
Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.
Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.

This patch contains a handful of small fixes to allow the Ebony's
flash to be exposed as MTD devices via the physmap_of driver.
Specifically it:
- Makes a small addition to the device tree and zImage wrapper
to record the correct address for the flash in the device tree based
on the board switches as reported via an FPGA register.
- Prohibits building the old hard-coded "Ebony" flash map on
arch/powerpc kernels, in favour of using physmap_of's device tree
based approach.
- Enables MTD and physmap_of in the Ebony defconfig.

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.

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.

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.
