Allow generic frame-buffer code to correctly write texts and blit images for
1, 2 and 4 bit per pixel frame-buffer organizations when pixels in bytes are
organized to in opposite order than bytes in long type.
Overhead should be reasonable. If option is not selected, than compiler
should eliminate completely all overhead.
The feature is disabled at compile time if CONFIG_FB_CFB_REV_PIXELS_IN_BYTE is
not set.

Convert helper functions to macros if feature is not enabled.

This patch adds pixelclock field to the s3c2410fb_display structure and make
use of it in the driver.
The Bast machine defined 9 modes but pixclock and margin values are defined
only for the 640x480 modes so I removed other modes.
This patch also fixes wrong display type constant for the SMDK2440 board.

This patch adds support for the other three palette formats possible with
the PXA LCD controller. This is required on boards where an LCD is connected
with all its 18 bits. With this patch, it's possible to use an 8-bit mode
with 18-bit palette entries. This used to be possible in 2.4 kernels but
disappeared in 2.6. With current kernels, you can only get wrong colours
out of an LCD connected this way.
Users can choose the palette format by doing something like this
in their board definition:
static struct pxafb_mach_info my_fb_info = {
[...]
.lccr3 = LCCR3_OutEnH | LCCR3_PixFlEdg | LCCR3_PDFOR_3,
.lccr4 = LCCR4_PAL_FOR_2,
[...]

This contains the following changes:
* Overlay surface alpha is configured separately from the overlay. This
prevents display glitches (configure and fill the overlay first, set
alpha to a visible value next)
* Added an ioctl for configuring transparency of the Overlay and graphics
planes. Blend mode, colorkey mode and global alpha mode are supported.
* Added an ioctl for setting the plane order. The overlay plance can be placed
over or
under the graphics plane.
* Added an ioctl for setting and reading chip registers, with mask.
* Updated copyright for 2007

uvesafb is an enhanced version of vesafb. It uses a userspace helper (v86d)
to execute calls to the x86 Video BIOS functions. The driver is not limited
to any specific arch and whether it works on a given arch or not depends on
that arch being supported by the userspace daemon. It has been tested on
x86_32 and x86_64.
A single BIOS call is represented by an instance of the uvesafb_ktask
structure. This structure contains a buffer, a completion struct and a
uvesafb_task substructure, containing the values of the x86 registers, a flags
field and a field indicating the length of the buffer. Whenever a BIOS call
is made in the driver, uvesafb_exec() builds a message using the uvesafb_task
substructure and the contents of the buffer. This message is then assigned a
random ack number and sent to the userspace daemon using the connector
interface.
The message's sequence number is used as an index for the uvfb_tasks array,
which provides a mapping from the messages coming from userspace to the
in-kernel uvesafb_ktask structs.
The userspace daemon performs the requested operation and sends a reply in the
form of a uvesafb_task struct and, optionally, a buffer. The seq and ack
numbers in the reply should be exactly the same as those in the request.
Each message from userspace is processed by uvesafb_cn_callback() and after
passing a few sanity checks leads to the completion of a BIOS call request.
