Support for the C2K cPCI Single Board Computer from GEFanuc
(PowerPC MPC7448 with a Marvell MV64460 chipset).
All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).
Part 2 of 5: support for the board in arch/powerpc/boot.

Added next-level-cache to the L1 and a reference to the new L2 label.
This is per the ePAPR 0.94 spec. Since we are't really dependent on this
today we aren't supporting the "legacy" l2-cache phandle that is specified
in the PPC v2.1 OF Binding spec.

At the moment we have a mixture of left-over version 0 and new-format
version 1 files in arch/powerpc/boot/dts. This is potentially
confusing to people new to the dts format attempting to figure it out.
So, this patch converts all the as-yet unconverted dts v0 files and
converts them to v1. They're mechanically-converted, and not hand
tweaked so in some cases they're not 100% in keeping with usual v1
style, but the convertor program does have some heuristics so the
discrepancies aren't too bad.
I have checked that this patch produces no changes to the resulting
dtb binaries.

The PowerPC 440EP, 440GR, 440EPx, and 440GRx chips have an issue that
causes the PLB3-to-PLB4 bridge to wait indefinitely for transaction
requests that cross the end-of-memory-range boundary. Since the DDR
controller only returns the valid portion of a read request, the bridge
will prevent other PLB masters from completing their transactions.
This implements the recommended workaround for this errata for chips that
use older versions of firmware that do not already handle it. The last
4KiB of memory are hidden from the kernel to prevent the problem
transactions from occurring.

The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs
All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0. Changing pixel clock has no effect
on other fbs.
Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry
before changing physical resolution on /dev/fb0
required command line parameters to preallocate memory for frame buffer diufb.
optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:
Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60
Bpp
bpp=32, bpp=24, or bpp=16
Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS
Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.
If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

The Xilinx 16550 uart core is not a standard 16550 because it uses
word-based addressing rather than byte-based adressing. With
additional properties it is compatible with the open firmware
'ns16550' compatible binding.
This code updates the ns16550 driver to use the reg-offset property
so that the Xilinx UART 16550 can be used with it. The reg-shift
was already being handled.

This patch modifies the Embedded Planet EP8248E device tree to reference the
SMC paramater RAM base register instead of the parameter RAM allocated by the

Now that we properly set the physical address in the program header of the
vmlinux ELF we can extract it to properly set the load and entry point for
u-boot uImages. Before we always hard coded the load & entry point to 0.
However there are situations that the kernel may be built with a non-zero
physical address.
We use objdump to extract the PHDR. We assume that there is only one
PHDR in the vmlinux of type LOAD.

The mv643xx_eth driver is being modified to support multiple instances
of the ethernet silicon block on the same platform. Each block contains
a single register bank containing the registers for up to three ports
interleaved within that bank. This patch updates the PowerPC OF to
platform_device glue code to support multiple silicon blocks, each
with up to three ethernet ports. The main difference is that we now
allow multiple mv64x60_shared platform_devices to be registered and
we provide each port platform_device with a pointer to its associated
shared platform_device. The pointer will not be used until the
mv643xx_eth driver changes are committed.
