Grant Likely 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.

John Linn 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.

Stephen Neuendorffer 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.

Labels and gotos are used in xilinxfb_assign to unwind allocations
on device registration failures.  Rename the labels to reflect the

to add new failout paths (which occurs in a subsuquent patch) and
to make reviewing the failout path easier.
