287e5d6fcc [POWERPC] XilinxFB: Allow fixed framebuffer base address
Allow a fixed framebuffer address to be assigned to the framebuffer device
instead of allocating the framebuffer from the consistent memory pool.

b4d6a7268f [POWERPC] XilinxFB: Add support for custom screen resolution
Some custom implementations of the xilinx fb can use resolutions other
than 640x480.  This patch allows the resolution to be specified in the
device tree or the xilinx_platform_data structure.

01ba1e9d26 [POWERPC] XilinxFB: Use pdata to pass around framebuffer parameters
The call to xilinxfb_assign is getting unwieldy when adding features
to the Xilinx framebuffer driver.  Change xilinxfb_assign() to accept
a pointer to a xilinxfb_platform_data structure to prepare for adding
additition configuration options.

e3cec00366 [POWERPC] XilinxFB: Make missing pdata structure non-fatal
Missing pdata structure is not a fatal error.  The device can still be
initialized without it.

31e8d4603e [POWERPC] XilinxFB: add of_platform bus binding
Adds the of_platform bus binding to the xilinxfb driver.  Needed to
use framebuffer devices described in the OF device tree (used by
arch/powerpc).

264776224d [POWERPC] XilinxFB: Split device setup from bus binding
Split the device setup code away from the platform bus binding.  This is
in preparation for adding the of_platform bus binding to this driver and
most of the setup code is common between the two busses.

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.

3cb3ec2c26 [POWERPC] XilinxFB: Replace calls to printk with dev_dbg, dev_err, etc.
The dev_dbg, dev_err, etc functions provide more context that plain
vanilla printk which is useful for debugging.  Where appropriate,
change printk calls to the appropriate dev_*() call.

Lack of pdata is not a fatal omission.  The driver can still be used even
if we do not know the screen dimensions.
