Kevin Hao fff69fd03d powerpc/83xx: factor out the common codes of setup arch functions
Factor out the common codes of setup arch functions to a separate
function. It does make no sense to print a board specific info
in setup arch functions, so use a more general one.

For ASP8347E board, there is no pci device node. So it is safe to
invoke mpc83xx_setup_pci() in its setup arch function even there is
no such invocation in its original setup arch function.

Benjamin Herrenschmidt 5657138404 powerpc: Move 32-bit probe() machine to later in the boot process
This converts all the 32-bit platforms to use the expanded device-tree
which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel
didn't rely on platform initializations to setup the MMU since it
sets it up entirely before probe_machine() so the move has comparatively
less consequences though it's a bigger patch.

Dmitry Eremin-Solenikov bede480d45 powerpc/83xx: merge PCI bridge additions
Nearly all mpc83xx-based boards have a common piece of code - one that
loops over all pci/pcie bridges and registers them. Merge that code into
a special function common to all boards.

Dmitry Eremin-Solenikov 7669d58c66 powerpc/83xx: consolidate of_platform_bus_probe calls
83xx board files have a lot of duplication in
*_declare_of_platform_devices() functions. Merge that into a single
function common to most of the boards.

The only leftover is mpc834x_itx.c board file which explicitly asks for
fsl,pq2pro-localbus, as corresponding bindings don't provide
"simple-bus" compatibility in localbus node.

Dmitry Eremin-Solenikov d4fb5ebd83 powerpc/83xx: consolidate init_IRQ functions
On mpc83xx platform nearly all _init_IRQ functions look alike. They either
just setup ipic, or setup ipic and QE PIC. Separate this to special functions
to be either referenced from ppc_md, or called from board file.

Grant Likely a4f740cf33 of/flattree: Add of_flat_dt_match() helper function
This patch adds of_flat_dt_match() which tests a node for
compatibility with a list of values and converts the relevant powerpc
platform code to use it.  This approach simplifies the board support
code a bit.

Grant Likely 2dc1158137 of/device: Replace struct of_device with struct platform_device
of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

Anton Vorontsov 6971df4f5b powerpc/83xx: Add MCU LEDs support for MPC837xRDB and MPC8315RDB boards
There are two front-panel LEDs on MPC837xRDB and MPC8315RDB boards: PWR
and HDD. After adding appropriate nodes we can program these LEDs from
kernel and user space.

Anton Vorontsov 89f3729642 powerpc/83xx: Add eSDHC support for MPC837xE-RDB/WLAN boards
Actually, the support is already there, but it requires newer U-Boots
(to fill-in clock-frequency, and setup pin multiplexing).

Though, it appears that on RDB boards USBB pins aren't multiplexed
between USB and eSDHC (unlike MDS boards, where USB and eSDHC share
pctl and pwrfault pins).

So, for RDB boards we can safely setup pinmux and manually fill-in
clock-frequency, thus making eSDHC work even with older u-boots.

Anton Vorontsov fda4bd9bac powerpc/83xx: Add support for MPC8377E-WLAN boards
MPC8377E-WLAN are basically RDB boards except:

- RAM extended to 512 MB;
- NAND flash removed, NOR flash extended to 64 MB;
- Vitesse VSC7385 5-port switch removed, RTL8211B PHY added;
- Power management MCU removed;
- PCI slot removed, another mini-PCI slot added (IRQ routing changed);
- USB3300 PHY's ID pin grounded, thus USB port is host-only.

Anton Vorontsov 70b3adbba0 powerpc/83xx: Move gianfar mdio nodes under the ethernet nodes
Currently it doesn't matter where the mdio nodes are placed, but with
power management support (i.e. when sleep = <> properties will take
effect), mdio nodes placement will become important: mdio controller
is a part of the ethernet block, so the mdio nodes should be placed
correctly. Otherwise we may wrongly assume that MDIO controllers are
available during sleep.

This patch adds pcie nodes to the appropriate dts files, plus adds
some probing code for the boards.

Also, remove of_device_is_avaliable() check from the mpc837x_mds.c
board file, as mpc83xx_add_bridge() has the same check now.
