ps3fb: Enhance horizontal panning on firmware 1.90 and up:
  - On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying
    rectangles from XDR to DDR memory with different source and destination
    line lengths. Hence larger horizontal virtual resolutions can be supported
    (up to 16368 pixels).
  - As the actual frame buffer memory layout no longer matches the entries in
    ps3fb_res[], create fake struct ps3fb_ioctl_res data for the
    PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it
    keep on working.

ps3fb: Add virtual screen and panning support:
  - The vertical virtual screen size is limited by the amount of memory
    reserved for ps3fb,
  - The horizontal virtual screen size is limited to the fullscreen width,
  - Advertise that we support panning, so fbcon will use it if the virtual
    screen is enabled.
    Enabling a virtual screen (using `fbset -vyres nnn') can speed up text
    console scrolling by a factor of 10-15, depending on the video mode.

ps3fb: In the case of non-fullscreen video modes, there was a partial overlap
of the GPU command buffer and the frame buffer. Fix and cleanup various issues
with overlap and alignment:
  - Move the GPU command buffer from the beginning to the end of video memory
  - Exclude the GPU command buffer from the actual frame buffer memory
  - Align the start of the virtual frame buffer to PAGE_SIZE instead of to 64
    KiB, and don't waste memory if it's already aligned (for fullscreen modes)
  - Take into account the alignment when checking memory requirements and
    maximum number of frames
  - Make sure fb_fix_screeninfo.smem_start always points to the virtual frame
    buffer start, so we don't have to compensate for that in ps3fb_mmap()

The i.MX frame-buffer read operation should be faster for all configurations
then drawing each individual character again in response to scroll events.

The nonstandard fields allows to configure frame-buffer special options flags
for different display configurations by board specific initialization code.

One of such specific options is reversed order of pixels in each individual
byte.  i.MX frame-buffer seems to be designed for big-endian use first.  The
byte order is correctly configured for little-endian ordering, but if 1, 2 or
4 bits per pixel are used, pixels ordering is incompatible to Linux generic
frame-buffer drawing functions.

The patch "Allow generic BitBLT functions to work with swapped pixel order in
bytes" introduces required functionality into FBDEV core.  The pixels ordering
selection has to be enabled at compile time CONFIG_FB_CFB_REV_PIXELS_IN_BYTE
and for each display configuration which requires it by flag
FB_NONSTD_REV_PIX_IN_B in "nonstd" field of info structure.

This patch provides way for board specific code to select this option.

Various console drivers are able to resize the screen via the con_resize()
hook.  This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's.  One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware.  However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.

To work around this problem, add an extra parameter to con_resize().  This
parameter is ignored by drivers except for vgacon.  If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success.  If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware.  The
latter is the more correct behavior.

With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.

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.
