aa296a891d fbdev/xilinxfb: Fix improper casting and tighen up probe path
The xilinxfb driver is improperly casting a physical address to a
u32, and the probe routine isn't as straight forward as it could be.
(discovered by gcc spitting out warnings on most recent change to
xilinxfb driver).

This patch fixes the cast and simplifies the probe path.

dac4ccfb64 fbdev: Add PLB support and cleanup DCR in xilinxfb driver.
Added support for the new xps tft controller. The new core
has PLB interface support in addition to existing DCR interface.

Removed platform device support as both MicroBlaze and PowerPC
use device tree.

Previously, the dcr interface was assumed to be used in mmio mode,
and the register space of the dcr interface was precomputed and stuffed
into the device tree. This driver now makes use of the new dcr
infrastructure to represent the dcr interface. This enables the dcr
interface to be connected directly to a native dcr interface in a clean
way.

Added compatibility for ml507 dvi core.

a108096878 powerpc/virtex: fix various format/casting printk mismatches
Various printk format string in code used by the Xilinx Virtex platform
are not 32-bit/64-bit safe.  Add correct casting to fix the bugs.

0e349b0e2d [POWERPC] Xilinx: Update compatible to use values generated by BSP generator.
Mainly, this involves two changes:
1) xilinx->xlnx (recognized standard is to use the stock ticker)
2) In order to have the device tree focus on describing what the
hardware is as exactly as possible, the compatible strings contain the
full IP name and IP version.

01ba1e9d26 [POWERPC] XilinxFB: Use pdata to pass around framebuffer parameters
The call to xilinxfb_assign is getting unwieldy when adding features

a pointer to a xilinxfb_platform_data structure to prepare for adding
additition configuration options.

3fb99ce4e2 [POWERPC] XilinxFB: rename failout labels to reflect failure
Labels and gotos are used in xilinxfb_assign to unwind allocations
on device registration failures.  Rename the labels to reflect the
error which occured.  This change is being made to make it easier
to add new failout paths (which occurs in a subsuquent patch) and
to make reviewing the failout path easier.
