ps3fb: Add a `mode' parameter to ps3fb_get_res_table(), as in some cases it
should check the full-screen flag of the _new_ video mode instead of the
current video mode.
This bug caused spurious mode change failures when switching between
fullscreen and non-fullscreen modes using fbset, while ps3-video-mode worked
fine.

Fix the black and white stripes issue with WUXGA monitor via HDMI.
It seems that when we use a VESA resolution from boot up, the AV settings
driver could not be initialized correctly. In that case we need a dummy
packet before VESA setting.
[Geert] Refactored to reduce code duplication.

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.

There are a few nvidia hardware where the i2c port assignments are reversed,
i.e., the 1st i2c port is assigned to the secondary display and the 2nd i2c
port to the primary display. In most cases, if only 1 display is attached, or
if only 1 flatpanel and 1 analog display is attached, the port reversal is of
no consequence. However if 2 flatpanels are attached, it can cause display
problems.
There is no sane way of determining if the hardware reversed the i2c port
assignment, so the simplest fix is to add a boot/module option, "reverse_i2c
to explicitly reverse the i2c port.
This also restores i2c ordering back to the pre-2.6.22 state.

Currently, if the refresh rate is not specified, fb_find_mode() returns the
first known video mode with the requested resolution, which provides no
guarantees wrt the refresh rate. Change this so that the mode with the
highest refresh rate is returned when the driver provides a custom video mode
database and the monitor limits, and a mode with the safe 60 Hz refresh rate
otherwise.

Changed things:
1. vmalloc()/vfree() replaced with rvmalloc()/rvfree() (taken from
drivers/media/video/se401.c)
2. mmap method implemented (mostly taken from drivers/media/video/se401.c)
3. smem_start and smem_len fields of struct fb_fix_screeninfo initialized.
(smem_start initialized with virtual address, don't know if it is really
bad...)

This patch:
- disallows setting of virtual height above 2048 as it does
not work for accelerated copyarea and imageblit
- fixes blinking of pm2v cursor by pushing cursor outside
the display (x=2047)
- fixes hardware cursor position on Permedia 2 chips with
panning enabled
- enables hardware cursor by default

and always honor type of display set by default mode settings.

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 sets correct bits related to the byte ordering of the
framebuffer. This was tested on little endian kernel only. The big endian
kernel may require different settings.
The patch also adds 32 bpp mode which is called 24 bpp by Samsung. One
pixel takes 32 bits but only 24 bits are used in this mode.
